Black 50-foot SJTW extension cord 14/3 AWG with grounded three-prong plugs

Milspec Industries, Inc.

Milspec Industries, Inc. 50' Pro Power SJTW Extension Cord 14/3 AWG Black

SKU CH-3Y39-XGYGA

Supplies grounded power up to 15 A and 300 VAC over 50 ft with a 14/3 SJTW jacket that stays flexible in freezing temperatures

  • Extra reach for distant power sources with 50 ft length
  • Handles heavy-draw equipment up to 15 A continuous current
  • Stays flexible in freezing temperatures thanks to cold-weather jacket
  • Secure grounded connection via 3-prong male-to-female plugs
  • Built for job-site toughness with molded strain-relief ends

Power Reach

The Milspec 50' Pro Power SJTW Extension Cord delivers 15 A at 300 VAC through a 14/3 AWG, 100% copper conductor. Heavy-duty molded plugs with large strain reliefs prevent pull-out. Cold-weather compounds keep the 15.24 m length flexible well below freezing. It weighs 5.2 lbs and suits camera rigs needing grounded AC power at distance.

Upgrade Path

Replaces lighter-gauge or stiff-jacket cords that crack in cold weather or fail at the plug junction. The jump is worth it when runs exceed shorter leads, when outdoor temperatures drop below freezing, or when frequent coil-and-uncoil cycles demand extra strain relief and copper flexibility.

Setup Check

Confirm the equipment draws no more than 15 A at 300 VAC and uses a standard three-prong grounded inlet. Verify the 50 ft route avoids pinch points and that the 2.36 kg weight is supported where the cord hangs. Ensure local codes permit SJTW-rated cable for the intended temporary power application.

Questions about this item

What clearance does the 14/3 AWG cord need for the moulded 3-prong plugs and strain-relief ends?

The moulded plugs with large strain reliefs add bulk at each end; allow at least 50 mm beyond the 15.24 m cable length so the reliefs do not bend sharply.

How do I install the cord without damaging the cold-weather jacket?

Uncoil the full 50 ft length before first use, lay it flat to remove twists, then connect the grounded male to the supply and the female to the load — never pull the cord by the jacket to seat the plugs.

When should I replace the cord given the 15 A / 300 VAC rating?

Replace it if the jacket shows cracks, the strain reliefs split, the blades bend, or the cord feels warm during a 15 A load — any of those mean the 100 % copper conductors can no longer carry rated current safely.
