2×12 vs. 3×14 vs. 2×14 AWG
2 × 12 AWG
The heavier two-wire build: 12 AWG for longer cords and bigger loads than 14 AWG will take.
3 × 14 AWG
Three conductors at 14 AWG, in black, white, and red, for cords that need a third conductor.
2 × 14 AWG
The lighter two-wire build, for everyday cords and light equipment.
Buying SJT Cord Wholesale — FAQ
What is SJT cord?
SJT stands for Service Junior Thermoplastic: a 300 V flexible cord with a thermoplastic (PVC) jacket. It is the standard build for extension cords, appliance and equipment power cords, and portable tools. These run Class K soft copper at 60 °C, with PVC insulation and jacket to UL 62.
SJT, SJOOW, or SO — which one do I need?
SJT is the value choice for indoor and light-duty cords at 300 V. Where oil, outdoor exposure, or cold flexibility is in the spec, you want SJOOW; where the circuit is 600 V, you want SO-type cord. We list SJT here; if your job calls for the others, ask and we will tell you straight whether we can supply them.
Which sizes and conductor counts are available?
Three builds: 2×12 AWG and 2×14 AWG with black and white conductors, and 3×14 AWG with black, white, and red. Jacket outside diameter runs 10.16 mm on the 2×12, 9.11 mm on the 3×14, and 8.49 mm on the 2×14.
Is it UL listed?
The insulation and jacket are built to UL 62, the standard for flexible cords, and the copper to ASTM B3 and B174. A standard and a listing are not the same document. If your job needs a UL listing mark on the cord, ask for the certificate with the quote so it is in writing.
Can SJT run inside a wall or conduit?
No. Flexible cord is not a substitute for fixed building wiring. For branch circuits inside walls or conduit, run THHN/THWN-2 in EMT or PVC conduit, and keep the SJT for cords and equipment connections.
How is it packed?
On closed reels with a lamiflex wrap. The 2×12 comes in 1,000 m reels at 181 kg gross, the 2×14 in 1,000 m reels at 131 kg gross, and the 3×14 in 500 m reels at 89 kg gross. Reel diameters run 0.61 to 0.80 m.
What does the jacket marking say?
Size, conductor count, type, voltage, jacket material, temperature, and area, printed along the length — for example "12/2 AWG SJT 300 V PVC 60°C 2C (3.31 mm²)". That marking is the rating an inspector reads, so it is worth checking against the spec before the reels ship.
What is the minimum order?
No fixed minimum. The question is whether the math works by the reel or by the container, mixed with THHN, conduit, or other electrical material. Send the builds, the reel count, and the destination and we put the quote together.
