Our take on the 50 Amp Generator Extension Cord with Power Inlet Box, Heavy Duty 3 Prong Extension Cord Twist Locking Adapter Plug for RV Camper & Generator to House, ETL Listed

This Hill's kit pairs a 25 ft 50 amp generator cord with a NEMA SS2-50 power inlet box, so a generator can feed a house panel or RV through one connection. The cord uses STW 6/3 + 8/1 AWG copper with three thick 6 AWG conductors for low resistance, and the PVC jacket resists sunlight, water and abrasion. The inlet box is PC plastic with an anti-rust coating, a flip-top cover with a green indicator light, and four pre-drilled holes. It suits homeowners wiring a generator inlet and RV owners needing a long 50 amp run; against generic 8/4 or 10/4 cords, the heavier conductors and included inlet box are the main edge.

About the 50 Amp Generator Extension Cord with Power Inlet Box, Heavy Duty 3 Prong Extension Cord Twist Locking Adapter Plug for RV Camper & Generator to House, ETL Listed

This is a 50 amp generator extension cord set with a power inlet box. It connects a generator to a home or to an RV or camper. The inlet box can also be used outdoors, for example with RVs, yachts, picnics and parties.

The cord uses STW 6/3 + 8/1 AWG wire with three 6 AWG conductors. The outer jacket is heavy-duty PVC that protects against sunlight, water, abrasion and aging. The male plug has a grip for easy plugging and unplugging. The female connector has pin holes that make the inlet box easy to locate. Its twist-lock design holds the connection and provides waterproofing.

The inlet box shell is made of PC material with an anti-rust coating and is drop-resistant. It has four pre-drilled holes and can be taken apart without tools. A green indicator light on the flip-top cover helps guide use in bad weather or during a power outage.

Questions and answers

Will this cord plug into my generator and house inlet?
The male end is NEMA 14-50P and the female end is NEMA SS2-50R twist-lock. Your generator outlet must be 14-50R, and your inlet must be SS2-50, not 14-50.
What wire gauge does the cord use?
It is STW 6/3 + 8/1 AWG: three 6 AWG conductors plus an 8 AWG ground. That is heavier than common 8/4 cords and keeps voltage drop lower over the run.
How much power can it carry?
It is rated 125/250V and up to 12,500W at 50 amps, matching a typical 50 amp generator or RV feed.
Does the inlet box need drilling?
It has four pre-drilled holes and the shell can be opened without tools. You still mount it to the wall with your own fasteners.
Can the inlet box stay outside in rain?
The flip-top cover and twist-lock connection are designed for outdoor use, and the PVC jacket resists water and sunlight. Keep the cover closed when not in use.
Is it ETL listed?
Yes, the product is ETL listed for the stated 50 amp, 125/250V service.
