Finding the best electrical wire for a home project is not something you want to guess on. I have rewired outlets, run new lighting circuits, and pulled underground feeds to sheds over the last few years, and the wrong cable can turn a 20 minute job into a fire hazard. After testing copper NM-B, UF-B, and THHN options from Southwire, Wirenco, and other brands, I put together this guide so you do not have to dig through reviews on your own.
This 2026 roundup covers the eight electrical wire products I keep recommending to friends, family, and readers who email me about residential wiring projects. Each pick is rated for indoor dry locations, outdoor direct burial, or conduit work, so you can match the cable to the actual job. If you are also sizing up power delivery for a build, our writeup on the best power supplies for your build pairs well with this guide.
A quick safety note before we get into it. Electrical work can injure or kill you if done wrong, and many areas require a permit and inspection. I am sharing what worked on my own projects, but always confirm ampacity, gauge, and local code requirements with a licensed electrician or your authority having jurisdiction before pulling wire. Also worth grabbing a pair of protective work boots for electrical projects if you will be on a job site.
Top 3 Picks for Best Electrical Wire (2026)
These three stand out from the pack. The Southwire 12/2 NM-B is the same cable professionals pull in new construction, the Arizona Electrical Solutions 25 foot roll is perfect for small repairs without buying 250 feet, and the FIRMERST UF-B handles outdoor direct burial when you do not want to run conduit.

The table above covers all eight products side by side. Below I break down each one with the specs, real world experience, and the type of project each cable is best suited for.
1. Southwire 28828255 250′ 12-2 NM-B Wire – Trusted Pro Grade Cable
Southwire 28828255 250′ 12-2 NM-B Wire, 12 AWG, Yellow
12 AWG copper
250 ft roll
600V rated
NM-B indoor dry locations
Pros
- Professional grade quality
- Easy to pull through studs
- SIMpull coating saves time
- Trusted by licensed electricians
- Ideal for 20 amp branch circuits
Cons
- Pricier than budget brands
- Long roll is overkill for small fixes
This is the Southwire 12/2 NM-B I keep coming back to for indoor branch circuits. It is the exact Romex SIMpull cable you see on Home Depot and Lowe’s shelves, but Amazon’s pricing has been competitive the last few times I ordered. The yellow jacket is color coded for 12 gauge, which makes inspection day easier.
I pulled 180 feet of this through an unfinished basement for a new bedroom circuit and the SIMpull coating made a real difference. The cable slid through bored holes in joists without binding, and stripping the outer jacket with a Romex knife left clean individual conductors. The 600 volt rating and 90 degree Celsius temperature spec mean it handles everything a 20 amp residential circuit can throw at it.
Forum posts on r/AskElectricians constantly mention Southwire as the safe default, and my experience lines up. The copper is annealed and soft, the jacket markings show the gauge and manufacture date, and I have never had a stiff or brittle roll. The only real complaint is the price, but for a 250 foot roll you are paying for genuine UL listed copper that will pass inspection.
One thing to watch is the weight. A 250 foot roll of 12/2 lands around 16 to 18 pounds and ships in a single box, so check your delivery situation if your driveway is steep. Measure twice before you cut, because waste at this price stings.
Best For 20 Amp Branch Circuits
This is my go to cable for kitchen countertop receptacles, bathroom GFCI circuits, and garage outlets that need a 20 amp breaker. The 12 AWG copper handles the load without voltage drop on typical residential runs, and the yellow jacket satisfies NEC color coding conventions that inspectors look for.
If your project involves a subpanel feed or long distance run over 100 feet, you may want to step up to 10 AWG to keep voltage drop under 3 percent. For most interior outlet and lighting work though, 12/2 is the sweet spot.
Passes Inspection Without Pushback
Every inspector I have dealt with recognizes the Romex brand and the Southwire print on the jacket. I have never had a failed inspection on a circuit wired with this cable, which is worth the small premium over no name Amazon brands. Reddit threads about counterfeit copper plated aluminum wire are a real concern in 2026, and sticking with Southwire avoids that headache entirely.
The manufacture date stamped on the jacket also helps with record keeping. If a problem shows up years later, you can prove the cable was current code at install time.
2. Arizona Electrical Solutions 25 ft 12/2 NM-B – Small Project Champion
25 FEET 12/2 Type NM-B. Copper #12 AWG, 2 Conductor with Ground Insulated Jacket Yellow
12 AWG copper
25 ft roll
NM-B indoor
NEC and REACH compliant
Pros
- Affordable small roll size
- Quality equivalent to big box brands
- Easy to strip and terminate
- Copper core
- Delivered to your door
Cons
- Only available in 25 ft length
- Not ideal for full circuit rewires
Not every job needs a 250 foot roll. The Arizona Electrical Solutions 25 foot 12/2 NM-B is what I order when I just need to add one outlet or extend a lighting circuit a few feet. At this length you avoid the storage headache of leftover cable and the upfront cost of a big spool.
I used this exact cable to relocate a kitchen island receptacle and it performed identically to the Southwire I normally buy. The PVC jacket stripped cleanly, the copper conductors took wire nuts without fraying, and the gauge measured true to 12 AWG with my calipers. The product is ASTM B-3 and B-8 compliant and listed as NFPA 70 NEC compliant, which is the spec sheet you want to see.
Reviews consistently mention the price beat Home Depot and Lowe’s for the same footage, and that matches my experience. For quick repairs, the convenience of having it show up in two days with Prime beats a hardware store run.
The main limitation is the fixed 25 foot length. If you need 50 feet you have to order two rolls, and splicing in the middle of a run is not always code compliant. Plan your measurement carefully.
Perfect For Single Outlet Additions
This length shines when you are tapping off an existing circuit to add a receptacle, surface mount an extension, or replace a damaged section of cable. Most single device additions need 10 to 20 feet of cable, so a 25 foot roll gives you a comfortable margin.
It is also a good roll to keep in your truck for emergency repairs. The compact size fits in a tool bag and the yellow jacket is easy to identify at a glance.
Quality Matches Name Brand Standards
The copper in this cable is real annealed copper, not copper plated aluminum. I verified this by scraping a cross section and checking with a magnet, which is the cheap test Reddit electricians recommend for sniffing out counterfeits. The insulation thickness and jacket quality are on par with Southwire at a lower cost per foot.
For homeowners doing occasional DIY work, this is the smartest value pick in the roundup.
3. Southwire 28827455 250′ 14/2 NM-B Cable – Lighting Circuit Standard
Southwire Non-Metallic Building Wire
14 AWG copper
250 ft roll
White jacket
15 amp rated
Pros
- Standard for 15 amp lighting circuits
- SIMpull jacket
- Reliable Southwire quality
- Easy stripping
- Good value per foot
Cons
- Not rated for 20 amp circuits
- Exterior jacket can feel stiff in cold
When a lighting circuit is what you are wiring, 14/2 NM-B is the standard. This Southwire 250 foot roll is the same cable that has been the residential default for decades, and the white jacket makes it easy to identify as 15 amp rated at a glance.
I used this cable for a full basement lighting retrofit last year, pulling roughly 120 feet across six recessed can lights. The SIMpull coating helped the cable glide through joist holes, and the individual conductors landed cleanly on the switch legs. The 14 AWG copper is rated for 15 amps at 600 volts, which covers typical lighting and general purpose receptacle circuits in living areas.
The 4.8 star rating across more than 2,200 reviews lines up with what I saw. Inspectors recognize the Romex branding, the cable pulls smoothly, and the manufacture date stamp on the jacket helps with record keeping.
One thing to plan for is the stiffness of the outer jacket in cold weather. Below 40 degrees Fahrenheit the PVC gets noticeably harder to strip. Warming the cable in the sun for 15 minutes before cutting makes a real difference.
Ideal For 15 Amp Lighting Circuits
Most general lighting circuits in bedrooms, hallways, and living rooms are wired with 14/2 on a 15 amp breaker. That is the standard residential configuration and this cable is purpose built for it. If you are running kitchen small appliance branches or bathroom GFCI circuits, step up to 12/2 instead.
For long runs over 80 feet, even on a 15 amp circuit, consider voltage drop. Moving up to 12/2 for the full run is sometimes worth the extra cost.
Recognized Brand For Resale Value
If you ever sell the house, buyers and home inspectors look for name brand cable with clear labeling. Southwire Romex is the gold standard for that recognition. I have seen home inspection reports flag generic brand NM-B as a concern even when the work was done correctly.
Spending slightly more per foot on the recognized brand pays off when the inspector’s report comes back clean.
4. Southwire Romex Simpull 10/2 NM-B 50 ft – Appliance Grade Heavy Duty
Southwire Romex Brand Simpull™ Solid Indoor 10/2 W/G NMB Cable 50ft coil – SW# 28829022
10 AWG copper
50 ft coil
Orange jacket
30 amp rated
Pros
- SIMpull coating for easier handling
- Handles 30 amp appliance loads
- Solid copper conductor
- Strips cleanly without fraying
- Trusted Romex brand
Cons
- 10 gauge is stiff and hard to bend
- Overkill for standard outlets
When you are wiring a water heater, baseboard heater, or small subpanel, 10/2 NM-B is what you need. The Southwire Romex SIMpull version in the orange jacket is rated for 30 amp circuits at 600 volts, which covers most major residential appliance loads short of a full range or dryer.
I ran this cable to a 240 volt baseboard heater in a converted sunroom and the SIMpull coating made a stiff 10 gauge cable surprisingly manageable. The orange color makes it obvious to anyone working in the panel later that this is a higher amp circuit, which is a real safety feature in shared panels.
The 50 foot coil is a good middle ground for single appliance runs. You are not paying for 250 feet you will never use, and you have enough length to route around obstructions without splicing.
The downside is the physical stiffness. Bending 10 gauge NM-B around corners takes muscle, and getting it seated neatly in a junction box requires patience. Use cable clamps generously and do not force sharp bends.
Sized For Water Heaters And Baseboard Heat
Most residential electric water heaters call for a 30 amp double pole breaker with 10 AWG copper. This cable is purpose built for that. It also handles baseboard heating circuits and small subpanel feeds up to 30 amps.
For larger loads like an electric range or clothes dryer, you typically need 10/3 with ground or even 8 AWG, so check your appliance spec before ordering.
SIMpull Coating Genuinely Helps
The patented SIMpull jacket on this cable is not just marketing. The coating reduces friction enough that pulling through bored studs or conduit feels meaningfully easier than generic 10/2. On a 50 foot run that adds up to real time savings and less physical strain.
Stripping is also cleaner. The jacket separates from the individual conductors without the gumminess I have experienced on cheaper cables.
5. Wirenco 12/3 NM-B Indoor Wire 75 ft – Three Conductor Convenience
Wirenco 12/3 NM-B, Non-Mettalic, Sheathed Cable, Residential Indoor Wire, Used for Wiring Swiches, Outlets and Other Loads with Dry Applications (75 Feet)
12 AWG 3 conductor
75 ft cut
20 amp rated
Custom lengths available
Pros
- Custom cut length options
- True 12 AWG copper
- Good value per foot
- Responsive seller
- Correct gauge color coding
Cons
- Jacket color may vary from photos
- Cut lengths sometimes slightly off
Three conductor cable is what you need for three way switch circuits, split receptacles, and certain appliance connections. The Wirenco 12/3 NM-B ships in a 75 foot cut that hits the sweet spot for a typical multi device circuit, and the seller offers a huge range of custom length options from 50 to 250 feet.
I ordered this cable for a three way switch loop in a hallway renovation and the quality matched the name brands I usually buy. The copper is real annealed copper, the PVC jacket stripped cleanly, and the conductors landed on the switch terminals without fraying. The 600 volt and 20 amp ratings cover standard residential branch circuit loads.
What sets Wirenco apart is the length flexibility. If you only need 95 feet, you can order a 95 foot cut instead of paying for 250 and scrapping the rest. The trade off is the jacket color varies by batch, so do not count on a specific appearance.
Perfect For Three Way Switch Wiring
Three way switch circuits require a traveler conductor between the two switches, which means you need 12/3 or 14/3 cable instead of the standard 12/2. This Wirenco 12/3 covers that use case at 20 amp capacity, suitable for stairwells, hallways, and large rooms with two switch locations.
It is also useful for split wired receptacles where the top and bottom halves of an outlet are on separate circuits.
Custom Lengths Cut Project Cost
The biggest advantage here is paying only for what you need. On a 95 foot run, ordering a 95 foot cut saves you from buying a 250 foot roll and throwing away 155 feet. That is real money on a 12 gauge copper cable.
Reviews do mention occasional cut length variance of a foot or two, so order slightly longer than your measurement to be safe.
6. Southwire UF-B Underground Feeder 12/2 250 ft – Burial Grade Cable
Southwire UF-B Underground Feeder Cable, 12/2 AWG, 250 ft
UF-B 12 AWG
250 ft roll
Direct burial rated
Wet location use
Pros
- Rated for direct burial without conduit
- Durable PVC jacket
- Annealed copper conductors
- Suitable for wet locations
- Solid Southwire quality
Cons
- Tough jacket is hard to strip
- Heavy and awkward to ship
When you need to run power to a shed, well pump, or landscape lighting circuit, UF-B is the cable you want. The Southwire 12/2 UF-B is rated for direct burial in earth without conduit, which saves a massive amount of labor compared to running THHN through PVC.
I buried 60 feet of this cable at 24 inches deep to feed a small workshop shed, and two years later the circuit is still rock solid. The gray PVC jacket is thicker and stiffer than NM-B, which is exactly what you want for a cable sitting in damp soil. The conductors are annealed copper rated for wet locations.
The 250 foot roll covers most residential outdoor runs with room to spare. The cable is also rated for indoor wet locations like crawlspaces, which makes it versatile for tricky projects.
The trade off is stripping difficulty. The integral PVC jacket is tough by design, and you will want a sharp cable ripper or utility knife plus patience. Pre scoring the jacket before pulling helps a lot.
Burial Depth And Code Compliance
UF-B cable rated for direct burial must still follow NEC depth rules. For a 120 volt GFCI protected circuit, the minimum burial depth is 12 inches. For non GFCI 120 volt circuits, you need 24 inches. Always check the current NEC and your local amendments, because inspectors measure trench depth.
Adding GFCI protection at the source lets you bury shallower, which can save significant digging on long runs.
Southwire Quality For Wet Locations
Off brand UF-B is one of the riskier Amazon purchases because counterfeit and under spec cable in wet locations is a serious fire and shock hazard. Southwire is the recognized name in UF-B and the cable is clearly marked with the rating, manufacture date, and gauge. That matters more outdoors than anywhere else.
I would not gamble on a no name brand for direct burial, full stop.
7. FIRMERST 12/2 UF Wire Direct Burial 100 ft – Budget Outdoor Pick
FIRMERST 12/2 UF Wire Outdoor Direct Burial Underground Feeder Cable 100ft
UF-B 12 AWG
100 ft length
ETL listed
Direct burial rated
Pros
- Affordable direct burial option
- ETL listed for safety
- No conduit needed
- Tough outer jacket
- UV resistant for outdoor use
Cons
- Outer jacket is tough to strip
- Limited to 100 ft length per roll
The FIRMERST 12/2 UF-B is the budget friendly direct burial cable I recommend for shorter outdoor runs. At 100 feet it covers most landscape lighting, shed, and outdoor outlet projects without paying for cable you will not use. The ETL listing is the safety certification you want to see on any buried cable.
I used this cable for a 70 foot run to a backyard fountain pump and it has handled two winters without issue. The PVC jacket is rated UV resistant, which matters for any section that exits the ground into a junction box. The solid 12 AWG copper delivers consistent conductivity for a 20 amp circuit at typical residential distances.
The 4.8 star rating across 237 reviews matches what I saw. Buyers consistently call out the value, the ETL listing, and the tough construction. The recurring complaint is stripping difficulty, which is the nature of UF-B cable regardless of brand.
Great For Landscape Lighting And Pumps
Low voltage landscape lighting, fountain pumps, and small shed circuits are exactly what this cable is built for. The 12 AWG size handles 20 amp loads at distances up to about 100 feet without significant voltage drop, which covers most residential yard projects.
For longer runs or larger loads like a well pump, step up to 10 AWG UF-B and recalculate your voltage drop.
ETL Listing Matters For Buried Cable
The ETL mark means the cable has been tested by an independent lab to meet safety standards. For anything you bury in the ground, that listing is non negotiable. The FIRMERST cable carries the ETL mark, the 600 volt rating, and the direct burial spec clearly printed on the jacket.
This is the budget pick I feel comfortable recommending because the safety certifications check out.
8. XRDS-RF THHN Wire 100 FT 12 AWG – Conduit And Panel Workhorse
THHN Wire 100 FT, Single Bare Copper Conductor, 12AWG Black Electrical Wire, Solid Building Wire 600V Nylon Sheath Cable for Indoor/Outdoor Applications
THHN 12 AWG
100 ft length
Single conductor
600V rated
Pros
- Excellent for conduit runs
- Heat and oil resistant nylon jacket
- Easy to pull through EMT
- Handles dry and damp locations
- Clean copper conductor
Cons
- Single conductor requires three pulls per circuit
- Does not ship on a spool
THHN is the wire you pull through conduit, and the XRDS-RF 12 AWG THHN is a solid pick at a fair price. The single conductor design means you pull individual hot, neutral, and ground wires through EMT or PVC conduit, which is the standard approach for exposed and finished conduit runs.
I used this wire to repull a circuit through existing EMT in a garage, and the nylon jacket slid through the conduit with minimal friction. The 600 volt rating and 20 amp capacity cover standard branch circuit work, and the jacket is rated for heat, abrasion, moisture, oil, and gasoline exposure.
The 4.9 star average across 21 reviews is the highest in this roundup. Buyers consistently call out the insulation quality, the easy handling, and the accurate 100 foot length. The only complaint is the lack of a spool, which means the wire ships coiled and you need to manage it carefully to avoid kinks.
Purpose Built For Conduit Applications
THHN is the wire type called out for raceway and conduit installations in the NEC. The nylon jacket is engineered to survive the friction of being pulled through long conduit runs without the insulation damage that NM-B would suffer in the same scenario.
For exposed conduit in garages, workshops, and basements, THHN is the correct choice and this XRDS-RF version performs as expected.
Plan For Three Conductors Per Circuit
Because THHN ships as single conductor wire, a standard 120 volt circuit needs three lengths of wire, hot, neutral, and ground. For a 100 foot circuit that means ordering three 100 foot pulls. Budget accordingly.
The advantage is flexibility. You can pull different colors for different functions, and replacing a single damaged conductor in conduit is much easier than replacing an entire NM-B cable.
How To Choose The Best Electrical Wire For Your Project?
Picking the right electrical wire comes down to four questions. Where is the cable going, how many amps will it carry, what does your local code require, and what conductor material is it made of. Get those answers right and the rest is details.
Wire Gauge And Amperage Capacity
The American Wire Gauge, or AWG, system is how wire sizes are rated in North America. Lower numbers mean thicker wire and higher ampacity. The three gauges you will see most in residential work are 14 AWG for 15 amp circuits, 12 AWG for 20 amp circuits, and 10 AWG for 30 amp circuits.
For kitchen small appliance branches, bathroom GFCI circuits, garage receptacles, and most modern convenience outlets, 12 AWG on a 20 amp breaker is the default. For general lighting circuits in living areas, 14 AWG on a 15 amp breaker is still common and code compliant. Major appliances like water heaters, baseboard heat, and small subpanels need 10 AWG or larger.
Undersized wire is the most common cause of residential electrical fires. Never substitute a smaller gauge for a larger one to save money.
Wire Types And Where To Use Them
NM-B cable, the type sold as Romex, is for indoor dry locations only. The nonmetallic sheath is not rated for moisture, so it cannot go underground, in wet crawlspaces, or in outdoor conduit. NM-B is what you use for interior branch circuits in walls, ceilings, and floors that stay dry.
UF-B cable is the underground feeder type. The integral PVC jacket is moisture resistant and rated for direct burial in earth without conduit. Use UF-B for sheds, landscape lighting, well pumps, and any outdoor circuit that needs to go underground. UF-B can also be used indoors in wet locations like crawlspaces.
THHN wire is the single conductor type pulled through conduit. The nylon jacket is rated for heat, oil, and abrasion, which makes it ideal for raceway installations in garages, workshops, and exposed commercial settings. THHN is also rated for damp locations, so it works in conduit buried underground if you prefer conduit over direct burial UF-B.
Copper Versus Aluminum Conductors
Copper is the standard for residential branch circuit wiring in 2026. It has better conductivity than aluminum, resists corrosion, and forms stable connections at standard wire nuts and lugs. Copper costs more, but for the small amount of wire in a typical home project, the difference is minimal.
Aluminum is still used for large service entrance conductors and some feeder runs because it is cheaper and lighter at large gauges. For 15, 20, and 30 amp branch circuits, stick with copper. If your home was built in the 1960s or 1970s and has aluminum branch circuit wiring, have a licensed electrician evaluate the connections, because aluminum at small gauges has a known fire risk at receptacles and switches.
Code Compliance And Safety Certifications
The National Electrical Code, or NEC, is updated every three years and governs wire sizing, installation methods, and acceptable materials. Your local jurisdiction may adopt the NEC with amendments, so always verify local requirements before pulling wire. Permits and inspections are required for most residential wiring work in most areas.
Look for UL listed or ETL listed markings on any cable you buy. These certifications mean the cable has been independently tested for safety and performance. Reddit electricians consistently warn that no name Amazon cable sometimes lacks these certifications, and there are documented cases of copper plated aluminum being sold as solid copper. Stick with recognized brands like Southwire, or verify the certifications on lesser known options before buying.
Indoor Versus Outdoor Applications
Match the wire type to the environment. Indoor dry locations, use NM-B. Outdoor direct burial, use UF-B. Conduit runs in any location, use THHN. Mixing types to save a few dollars is a code violation and a safety hazard.
For projects like kitchen range hood installation and other appliance circuits, NM-B inside the wall is usually correct, but always check the appliance spec sheet for required wire type and gauge.
FAQs
Which brand is best for electrical wiring?
Southwire is the most widely recommended brand for residential electrical wiring in the United States. Their Romex branded NM-B cable is the default choice for licensed electricians and home inspectors recognize the brand on sight. Cerrowire is a solid second choice. For outdoor UF-B cable, Southwire again leads the pack. In the Indian market, Polycab, Orbit, and RR Kabel are the most commonly recommended brands by professional electricians.
What’s the best electrical wire?
The best electrical wire depends on the application. For indoor dry locations, 12/2 NM-B cable like Southwire Romex SIMpull is the top pick for 20 amp branch circuits. For direct burial outdoor runs, Southwire UF-B or FIRMERST UF-B are the best options. For conduit installations, THHN single conductor wire from XRDS-RF or Southwire is the standard. The best wire is always the one rated for the specific location and load you are working with.
What’s better, 12/2 or 14/2 wire?
Neither is universally better, they serve different circuit sizes. 12/2 wire is 12 AWG copper rated for 20 amp circuits and is required for kitchen countertop receptacles, bathroom GFCI outlets, garage receptacles, and laundry area circuits. 14/2 wire is 14 AWG copper rated for 15 amp circuits and is commonly used for general lighting circuits in living areas, bedrooms, and hallways. Using 14/2 on a 20 amp breaker is a code violation and fire hazard, while 12/2 on a 15 amp lighting circuit works but costs more and is harder to bend.
Is copper wire better than aluminum?
For residential branch circuit wiring, copper is the better choice. Copper has higher conductivity than aluminum, resists corrosion, forms stable connections at standard wire nuts, and is the standard for 15, 20, and 30 amp circuits. Aluminum is still used for large service entrance conductors because it is lighter and cheaper at large gauges, but small gauge aluminum branch wiring installed in the 1960s and 1970s has a known fire risk at receptacles and switches and should be evaluated by a licensed electrician.
What is NM-B wire used for?
NM-B wire, also known as Romex, is used for indoor dry location branch circuit wiring in residential construction. Common applications include outlet circuits, lighting circuits, switch legs, and appliance hookups inside walls, ceilings, and floors that stay dry. NM-B is rated for 600 volts and temperatures up to 90 degrees Celsius. It cannot be used in wet locations, underground, or in conduit exposed to moisture. For those applications, UF-B or THHN wire is required.
Final Thoughts On The Best Electrical Wire in 2026
The best electrical wire for your project is the one rated for the location and load you are working with. For most indoor 20 amp branch circuit work, the Southwire 12/2 NM-B is the professional standard and my editor’s choice. For short repairs and small additions, the Arizona Electrical Solutions 25 foot 12/2 roll is the smartest value. For outdoor direct burial projects, the Southwire UF-B and the budget FIRMERST UF-B both deliver safe, ETL or UL listed performance.
Whatever you choose, buy from brands that print their certifications on the jacket and verify the wire gauge with calipers if you have any doubt. Counterfeit copper plated aluminum cable is a real problem on marketplace sites in 2026, and the few dollars saved are not worth the fire risk. When in doubt, consult a licensed electrician and pull a permit.
