30A Generator Cord Kit with 40FT Cable

This VEVOR kit supplies a 40-foot STW 10 AWG extension cord with NEMA L14-30P male and NEMA L14-30R female twist-lock connectors. A pre-drilled power inlet box with a NEMA L14-30P male end is included for mounting. ETL certification covers the cord and box assembly. The package adds a PVC carrying strap, a non-woven bag and three mounting screws.

Suits 30A Generator Backup Installations

Homeowners connecting a 30-amp portable generator to a fixed inlet will find the matching plugs and 40-foot reach convenient. The twist-lock design resists accidental disconnection during outdoor use. Buyers needing a different amperage, a longer run, or a hard-wired transfer switch should look at other equipment.

NEMA L14-30P to L14-30R Connector Pair

The cord terminates in a NEMA L14-30P plug for the generator and a NEMA L14-30R receptacle for the inlet box. The box itself presents a NEMA L14-30P male fitting for panel wiring. Confirm your generator outlet and panel inlet match these exact configurations before purchase.

Questions about this item

What can the 30 A rating actually power when the cord is connected to my generator?

The 10 AWG copper conductors carry up to 30 amps continuously, so the cord can run a 30 A inlet box feeding a transfer switch or RV panel without overheating.

How does the NEMA L14-30 twist-lock interface affect what I can plug in?

Both ends use the L14-30 configuration, so the male plug locks into a 30 A generator outlet and the female receptacle accepts only a matching L14-30P inlet box or adapter.

What clearance do I need to mount the pre-drilled inlet box on an exterior wall?

The box measures 6.1 by 3.8 by 3.5 inches with a 0.9 inch knockout, and it includes three screws for surface mounting on a flat stud or sheathing.
