FAQs

Can I use a 50A cord for my 30A RV?

Not directly – you’ll need a 50A-to-30A adapter. We recommend using properly rated cords to avoid safety risks.

How long can I safely run the 30A cord at full load?

Our 10/3 gauge cords handle 3750W continuously. Avoid exceeding 8 hours at max load for optimal safety.

Will the LED indicator work if the cord isn’t fully plugged in?

The light only activates when the connection is secure. No light? Check for loose plugs or tripped breakers.

Is the 50A cord safe for Tesla charging?

Absolutely. Our NEMA 14-50P/R cords are Level 2 EV-compatible, including Tesla (with manufacturer’s mobile connector).

Why does my industrial cord have a different plug (SS2-50R)

SS2-50R is a locking industrial plug. Use it with generators/welders – adapters available for RV hookups.

Can I daisy-chain two 30A cords for more length?

Never. Chaining cords risks overheating. Use a single cord of correct length (25ft/50ft options available).
