Safety & Use Notes

Verify your outlet and equipment are NEMA 14-50 and do not exceed 50 A. Fully uncoil cord for high loads to reduce heat. Use GFCI-protected circuits outdoors and keep all connections off the ground and away from standing water. Follow local electrical codes and device manufacturer guidance.

Frequently Asked Questions (FAQs)

1) What’s the conductor makeup “6/3 + 8/1”?

Three 6 AWG copper conductors carry Hot/Hot/Neutral, and one 8 AWG copper conductor is Ground — the standard build for many 14-50 cords.

2) Will this work for my welder?

If your welder uses a NEMA 14-50 plug and the branch circuit supports 50 A, yes. Always check your machine’s nameplate rating.

3) Is it suitable for RV shore power?

Yes. It extends 50 A RV service (14-50). Confirm campground pedestal type and keep connections weather-protected.

4) Can I use this for EV charging?

Yes, with a 14-50 EVSE. Set charging current per EVSE/vehicle recommendations and never exceed circuit rating.

5) What does STW mean?

STW is a service-grade, thermoplastic, weather-resistant jacket formulated for outdoor durability, UV resistance, and flexibility.

6) How heavy is the cord?

Approx. 35.4 lb (16.1 kg) per the package spec — store with the included strap for easier handling.

7) Does it have locking connectors?

No twist-lock; standard 14-50 straight-blade with molded, easy-grip handles for a secure manual fit.

8) Can I daisy-chain two cords?

Not recommended. Longer runs increase resistance and voltage drop. Use a single properly-sized cord.

9) What ambient conditions can it handle?

Rated for −40 °F to 140 °F (−40 °C to 60 °C). Keep connectors dry and sheltered during use.

10) What comes in the box?

One 50 ft NEMA 14-50P to 14-50R extension cord with easy-grip ends and a cord organizer strap.
