If you are wiring outlets in a house, the short answer is this: buy solid 12 AWG copper NM-B cable, and buy it from a listing that tells you the exact length and the amp rating up front. Everything else — jacket color, coil shape, brand name — is noise once you know what you are holding.
I’m Mohammad Maruf — the founder and writer behind KitchPrep. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
You need wire that won’t fail inspection or overheat behind your walls. All seven spools here meet the same baseline: solid copper conductors, a 600-volt rating (far more than the 120 volts a home outlet uses), and 12-gauge thickness rated for 20-amp household circuits (the standard for kitchen, bathroom, and garage outlets). We compare them on length, jacket style, and how they handle a real pull through studs and boxes. The top pick is the one that keeps showing up in finished basements and bathroom remodels, and the rest of this page explains why that matters for the 12 gauge wire for outlets spool you actually order.
Our Picks at a Glance
How To Choose The Best 12 Gauge Wire for Outlets
Choosing outlet wire is not really about brands. It is about matching three numbers to your project: the wire thickness, the voltage ceiling, and the length you actually need. Get those three right and almost any correctly labeled spool will do the job.
Start with the gauge, not the price tier
Twelve gauge — written as 12 AWG — is the standard choice for most household outlet runs. The number describes the wire’s thickness, and thicker wire carries more current without heating up.
That is why a 12-gauge line pair is the usual match for a 20-amp circuit, while thinner 14-gauge is normally reserved for 15-amp lighting-only runs. Pairing 12 AWG with a 20-amp breaker is the safe, code-following pairing most electricians expect to see behind a finished wall.
Solid versus stranded, and sheathed versus single conductor
Solid copper (a single firm wire inside the insulation) is what you want for pulling through drilled framing, because it holds a bend and pushes straight through a hole. Stranded wire is more flexible but harder to terminate neatly at a receptacle.
Sheathed cable — also called NM-B — bundles the black, white, and bare ground together inside one flat yellow jacket. That is the format used for outlet runs. Single-conductor THHN is a different animal: one insulated wire, sold on its own, used for conduit runs, grounding, and specialized jobs.
Match the length to the room, and add slack
Length is where cheap mistakes happen. Buy a spool that covers the outlet, the switch box, and a foot or two of slack at each end. A 50-foot cut is plenty for a single room or two small runs. A 100-foot coil covers a full basement or a kitchen with multiple receptacles, and having leftover wire on the shelf beats stopping mid-job to order a second roll.

In‑Depth Reviews
1. Southwire Romex Brand Simpull Solid Indoor 12/2 W/G NMB Cable 100ft Coil
Our pick — over 4.5★ from 10,000+ verified ratings; the strongest balance of quality and price.
The 100-foot yellow NM-B coil that most finished-basement rough-ins end up using.
The jacket here is the story. Southwire coats this coil in its patented SIMpull Cable Jacket, which is a low-friction outer layer that lets the whole flat cable slide through drilled studs and around corners without fighting you. On a long pull, that matters more than anything printed on the label.
It is a 100-foot coil of 12/2 NM-B — meaning two current-carrying 12 AWG conductors plus a bare ground wire — rated for 600 volts and built for branch circuits that feed switches and outlets. The two-conductor construction is the standard outlet format. What wins people over is the overall build consistency: the copper is uniform, the spacing between conductors is even, and the yellow jacket strips without shredding.
The praise from owners clusters heavily on one thing — quality, by a wide margin, with functionality a distant second. The general read is that you can pull a 12/2 run through conduit, around a corner, and into a box without any of the jacket bunching up or tearing. That consistency is why it holds a 4.8-star standing across more than 10,000 reviews, the tallest review profile in this lineup. One buyer’s assessment sums up the mood: “This Southwire 12-2 NM-B wire is an awesome value for the money. The 250-foot roll gives you plenty of wire for projects while staying affordable. Great quality and a great price—I’m very happy with the purchase.”
Where it earns its spot
- SIMpull jacket pulls and strips cleanly, so long runs take less effort
- 100-foot length covers a full basement, a kitchen, or three small rooms
- 12/2 with ground pattern — the standard format for 20-amp outlet runs
- 600-volt rating and dry-location design fit standard indoor branch circuits
What to know before you buy
- Dry and above-ground only — it is not a direct-burial or wet-location cable
- Solid copper resists tight bends, so plan your receptacle box depth before you pull
Reach for it if: you want one 100-foot coil that handles a whole-room or whole-basement rough-in without a second order.
Plan around: the dry-only rating — outdoors or underground, this coil is the wrong tool.
2. CIRENKO 12/2 NM-B Cable 100 FT, UL Listed 12 Gauge Indoor Wire with Ground
The 100-foot coil with a UL E-file number you can verify before an inspection.
Most outlet wire listings ask you to take the manufacturer’s word on where it sits in the code book. CIRENKO prints a UL E-file number on the product so you can look the certification up yourself — a small thing that turns into a large thing when a professional is signing off on the finish.
This wire carries the UL83 and UL719 safety listings (independent lab tests for electrical wire), so it’s ready for an inspected job. The specs back that up: two insulated 12 AWG copper conductors plus a bare ground wire, rated 600 volts and 20 amps, and clearly marked as copper rather than CCA (copper-clad aluminum, a cheaper imitation that carries current less efficiently). The jacket is the standard durable yellow NM-B sheath (the plastic coating that protects the wires inside) with printed markings running down the length. The CIRENKO coil below serves a different buyer — the one doing inspected, permitted work rather than a homeowner topping off a garage.
Buyers report this cable performs like the big national brand. The recurring note is that you get the length you ordered and the copper reads as real, with insulation that strips cleanly and quickly at each box. From the review pages: “Quality is on par with Southwire at a much lower cost.” A few people who grabbed it for outdoor or direct-burial work had to send it back, so if your job is a buried line, pick something rated for it — that is a task-fit issue, not a defect. The other piece buyers like is the coil discipline: it arrives wound tight, so unspooling stays orderly on the floor.
Paper trail edge: the verifiable UL E-file number is what earns this coil its place for anyone running work that will get inspected.
Confident verdict: this is the coil that best pairs code compliance with a 100-foot length at a fair tier of the market — ideal for a permitted basement finish or an addition.
Keep in mind: dry indoor locations only — a shed or garage outlet is fine, a buried line is not.
3. ARIZONA ELECTRICAL SOLUTIONS 12/2 NM-B Wire 100 ft Coil
One 100-foot coil covers kitchen receptacles, pancake lights, and a whole-room rewire.
Two insulated 12 AWG conductors and a grounding conductor, wrapped in a yellow non-metallic sheath rated 600 volts and 20 amps. It uses solid bare copper under PVC insulation with a nylon outer wrap, which is the layer that resists scrapes when you are dragging the cable across framing. The jacket prints the amp and volt rating directly on it, so you never have to guess mid-pull which run you grabbed.
For a homeowner replacing old receptacles or dropping a light fixture into a ceiling, the 100-foot length is forgiving. In a kitchen remodel, this is the coil that reaches from the panel through the ceiling joists to the countertop without requiring a splice in the middle of a run.
The main caution is a bare-minimum packaging situation — no printed label on the outside of the coil, just the wire wrapped and shipped. That has not stopped it from being one of the cleaner builds in this tier, and the copper and sheath both read as genuine. If you are picking this coil for a project where the inspector wants to see manufacturer paperwork on the box, order the CIRENKO above instead. For everyday outlet work around the house, the Arizona cable earns its keep.
Best for: anyone running outlets in a kitchen, a bedroom, or a full basement ceiling — the 100-foot length means fewer mid-job inventory surprises.
Downside to budget for: minimalist packaging — if you want an official-looking carton, this is not that.
4. Energeaster Solid Indoor 12/2 W/G NMB Cable 50ft
A 50-foot coil whose jacket bends around attic framing where stiffer 12-gauge cable fights back.
Two insulated conductors running parallel — one black, one white — with a bare 12 AWG ground wrapped in fire-retardant paper and laid between them, all under a yellow indoor NM-B jacket rated 600 volts. UL Listed and built to NEC guidelines, so the basics are all present. The conductors themselves are solid, which means you tighten them firmly onto a receptacle screw without the strands splaying.
Where this coil separates itself is flexibility. Owners repeatedly describe it as easy to manipulate through attic framing and behind wall cavities, especially compared to stiffer 12-gauge cable that refuses to make a tight corner. The bright yellow jacket is genuinely visible in an unlit attic, which reduces the chance of nicking it with a staple gun.
Two consistent notes surface: the cable can be stiff in cooler temperatures, and the outer jacket sometimes puts up a fight when you go to slice it open with a utility knife. Neither is a defect — it is the trade-off that comes with a protective indoor sheath — but plan to score the jacket carefully at each box rather than expecting it to peel off like softer insulation. Length has been reliable in practice: the coil arrives neat and unkinked, and owners mention no shortfalls against the advertised 50 feet.
Pulls that win people over
- Flexible jacket bends around corners better than stiffer solid-copper cable
- Bright yellow sheath is easy to spot in dim attic and basement cavities
- Solid 12 AWG copper holds a firm termination on outlet and switch screws
- 50-foot length is the right size for a single attic run or one LED panel circuit
Slow down and note
- Solid wire stiffens up in cold weather, so warm the coil before a winter pull
- The outer sheath needs a careful score to strip; harsh cuts risk nicking the conductor insulation
Pick this one for: tight attic pulls and short runs where flexibility saves your patience more than length ever would.
Not for: underground or wet-location runs — this is explicitly an indoor NM-B cable.
5. ARIZONA ELECTRICAL SOLUTIONS 12/2 NM-B Wire 50 FT
A 50-foot coil sized for one outlet run or two short runs, no full spool to haul around.
The build here is textbook 12/2: one black hot conductor, one white neutral, and a bare copper ground, all in a yellow non-metallic PVC sheath rated 600 volts and 20 amps. The insulation carries a 90°C heat rating, and the cable is built to ASTM B-3 and B-8 along with Federal Specification A-A-59544 and NEC Article 334. Translation: it is the kind of cable you would use to feed an outlet, a light switch, a dishwasher, a garbage disposal, or a garage receptacle without concern that it was assembled from leftover stock.
The flat sheath staples cleanly against a stud and feeds smoothly through drilled framing, which is why anyone roughing in a bathroom or a laundry area tends to move quickly with this coil. Owners describe it as arriving tightly wound and unmarred, cutting cleanly with lineman pliers and bending without kinks. The 50-foot length suits a single-room job perfectly — one wall of outlets, a set of ceiling fixtures, or a modest garage circuit.
One genuine quirk: the 50-foot coil ships rolled with minimal outer packaging. It is the same wire you would get from a full carton, just spooled plainly, which is also why the price lands a little softer than the branded alternative. If neat retail packaging matters on your jobsite, look at the CIRENKO listing above instead. For a weekend outlet add, the wire itself performs exactly as labeled.
Rough-in read: the flat jacket staples clean and the nylon coating resists nicks during long pulls, which is exactly what a fast rough-in wants from 12/2 cable.
Fine print: rolls loosely packaged — no printed box, so plan accordingly if a jobsite photo log is part of your permit file.
Suits: the homeowner or small contractor running one focused outlet or fixture circuit who does not need a full 100-foot coil.
Consider a different coil if: you are wiring an entire basement — the 50-foot length will run out before the job is finished.
6. Wirenco 12/2 NM-B Sheathed Cable, 50 Ft Cut
A 50-foot cut priced for one garage or utility-room outlet job, with slack left over.
Unlike the 100-foot coils above, the Wirenco spool is a 50-foot cut designed for exactly one job — usually a garage, a utility room, or a small room addition. It is #12 AWG residential wire for outlets, switches, and other standard loads, carrying a 600-volt maximum with an allowable ampacity of 20 amps. The copper conductors are rated for dry locations up to 90°C (194°F) and approved for both exposed and concealed installations.
Where this coil sits in the lineup is straightforward: the Wirenco lands shorter than the Southwire on length — 50 feet against 100 feet — and ships with a thinner outer shielding than the name-brand roll. That thinner shielding does make it a touch more stiff to strip at the box, but the conductors themselves are correctly gauged and the amp rating matches the rest of this tier.
What buyers like most is the value math. “Close to 100% same as SouthW Cerro, AZ etc.,” one buyer summed up. “Main difference is color and arrives square rounded rather than circle.” The one caution that recurs: an occasional order ships as 12/3 instead of 12/2, which is fine for a non-inspected garage outlet but a return for a permitted job. The coil arrives in a squared-off rather than round shape, which is unusual but harmless.
Where this spool holds its own
- 50-foot cut matches a single-room or garage outlet project without leftovers
- Correct 12 AWG copper with a 600-volt / 20-amp rating for standard branch circuits
- Dry-location rating up to 90°C covers typical indoor installs
Straight talk on the trade-offs
- Thinner outer shielding means more effort stripping at the box than name-brand NM-B
- Occasional mis-ships of 12/3 instead of 12/2 — check the label before you cut
Ideal when: you are running one garage outlet and want to stay firmly in the budget tier of the market.
skip it if: the job needs an inspection stamp — the UL paperwork on the CIRENKO coil is the safer match.
7. Kimbluth THHN Wire 12 Gauge Solid Copper, Black, 75FT
Not an outlet spool — 75 feet of single-conductor THHN for grounding and conduit pulls.
This wire is a completely different format from every coil above. THHN is one insulated conductor, not a sheathed bundle, and the Kimbluth roll gives you 75 feet of a single 12 AWG solid copper wire. The jacket is PA6 nylon over PVC (a two-layer sheath that adds abrasion and oil resistance), the maximum voltage is 600V, and the working temperature tops out at 90°C — the highest heat ceiling in this guide.
That makes this wire a natural fit for grounding runs, dedicated conduit pulls, and trades where you need one continuous conductor rather than a packaged hot-neutral-ground assembly. It is rated for both wet and dry environments, which opens up job sites that NM-B cannot touch. Against the Southwire above, the numbers swing the other way: the Kimbluth roll runs 3 strands against the Southwire’s 3, and the wire count reads 1 versus the Southwire’s 2. Different tools, different jobs.
Owners appreciate the quality and skin-flint value — copper that reads as genuine, with a thick enough jacket that the wire holds up when it is dragged through a length of PVC conduit. What buyers mention less often is the one thing to plan for: solid 12 AWG resists bending, so tight conduit elbows take patience. The recurring small gripe is that the listing does not carry a US code certification, which matters if an inspector will be looking at the run. On a house project, treat this as a grounding and conduit wire, not the coil you use to feed outlets.
Where it earns its keep: one continuous conductor for grounding and conduit work, with a 90°C ceiling that NM-B cannot match.
Right pick for: grounding a sub-panel, tracing an underground line, or pulling a single conductor through conduit.
Wrong pick for: feeding a household outlet directly — for that you want one of the sheathed 12/2 coils above.
Understanding the Specs
Gauge (12 AWG)
Gauge is just the wire’s thickness, and lower numbers mean thicker wire. Twelve gauge carries more current than thinner 14-gauge before it heats up, so it pairs naturally with a 20-amp household circuit. Match the gauge to the breaker and the job runs safely and within code.
NM-B vs THHN
NM-B (non-metallic sheathed cable) is the flat yellow bundle — hot, neutral, and bare ground in one jacket — used for runs between a panel and your outlets. THHN is single-conductor wire sold on its own, used for conduit runs, grounding, and specialty pulls. Reaching for the wrong one is the most common first-time wiring mistake.
Voltage and Ampacity
Every cable in this guide tops out at 600 volts, which is well above what a household branch circuit ever sees. Ampacity is how much current the wire can carry continuously — for 12 AWG copper, that is normally 20 amps on a standard branch circuit, matching a 20-amp breaker.
Location Rating
NM-B is rated for dry, indoor locations, including above ground and inside wall cavities. It is not permitted in wet locations or underground without protection. THHN works in both wet and dry environments, which is why it shows up for outdoor grounding, conduit, and other runs where the wall cavity is not an option.
