40 ft 50 A RV Generator Cord

This 40 ft extension cord carries 50 A at 110 V for up to 12500 W. It uses 6/3+8/1 AWG pure copper conductors and a NEMA 14-50P plug terminated in bare wire ends. The STW jacket is rated for indoor and outdoor use across a -40 °F to 140 °F range. An IP44 rating adds splash protection.

Suits RV shore power and generator hook-ups

The cord fits users who need a 50 A connection between a generator and an RV or transfer switch with bare-wire termination. It is not for buyers who require a different plug style, a shorter run, or a lower amperage rating. The fixed 40 ft length may be excessive for compact setups.

Check plug and termination compatibility

Verify that the power source accepts a NEMA 14-50P plug and that the destination can be wired to bare conductors. Confirm the 40 ft reach matches the installation distance. Ensure the environment stays within the -40 °F to 140 °F operating window. The package includes a storage strap for tidy coiling.

Questions about this item

Does my generator need a NEMA 14-50 outlet to use this 50A cord?

Yes, the cord ends in a NEMA 14-50P plug rated for 50 amps at 110 volts, so the generator or inlet must provide that exact receptacle.

Will the STW 6/3+8/1 cable stay flexible in freezing weather?

The STW-rated jacket is specified for -40 °F to 140 °F, so it remains pliable and manageable in sub-zero temperatures.

How can I confirm the bare-wire end is phased correctly after wiring it in?

With the generator running, measure 110 volts between each hot and the neutral, and verify the ground shows continuity to the generator frame.
