Product Description

Product Description

The Reliance Controls PB50 50-Amp NEMA 3R Power Inlet Box is a watertight electrical inlet box designed to be located outdoors where the generator is running in order to prevent dangerous carbon monoxide fumes from entering your house or other cherished space. This inlet box should be safely hardwired through an outside wall directly to the transfer switch or panel, eliminating the need for cords running through windows or doors. It was also designed to be wired directly to the transfer switch or panel by using one of the four included combination 1/2-inch and 3/4-inch knockouts (one on each side, bottom and back). The exclusive, patented make provides generous wiring space and facilitates rough-in. The face of the box is removable for easy placement and wiring and, finally, it was constructed of steel with rugged, anti-corrosive, powder-coated paint and has a spring-loaded inlet cap to prevent moisture front entering the front-mounted connector inlet when not in use. Since 1909, Reliance Controls Corporation has contributed more innovations than any other single manufacturer and has been awarded over 85 patents on manual transfer switches, time switches and accessories. Reliance Controls Corporation specializes in the manufacturing of a wide variety of electrical products. The primary product line consists of heavy duty time clocks and controls, generator accessories, transfer switches and transfer panels for portable generators. And after over a century of innovation, Reliance Controls Corporation has built an enviable reputation for high quality, superior engineering and exceptional customer service.

4.0 out of 5 stars No big deal, easy install
By rafael fernandez on September 9, 2019
Gets a 4 because the first box came with a broken screw. But other than that i really dont understand why people are having a hard time with maneuvering the wiring.. just dont make it longer than the ground and everything fits perfectly. I used 6 gauge insulated wire and no big deal. If you are trying to put slack cable in there then this isnt your box.

4.0 out of 5 stars Nice box.
By Brant on October 3, 2017
I like that this box comes with the flip lid, with weatherproofing foam. The Generac model I was looking at doesn’t come with one, must purchase separately for $23, really?? However, there are a couple minor issues I see. First is how the plug would fit into the box may create stress from the weight of the cord. My 50 amp cord is heavy. Therefore I will put a hook in the wall below to tie off the cord to reduce the stress on the outlet. Second, as others have stated, it is a bit tight to get the 6 gauge wires in there and get cover secured. All and all I am happy with it and hope it holds up over the years.

1.0 out of 5 stars Great Quality Box, BUT a real Knucklebuster
By Salvatore A Casale on June 11, 2018
So I read a lot of the reviews and still purchased this box due to to low profile and quality of which I really like. The downside however is trying to wire a matching 50amp, #6 wire into this guy...as the reviews warned. For anyone reading this, here's some advice. Make sure you have LOTS of time on your hands, a good pair of electrical pliers to battle the box and patience of a saint. Whatever you do, DON'T RUSH and analyze how the wires go in as there really is about 1/8th of an inch room in the back of the box. This causes you to form a 90 degree bend, which for me is not appropriate and scary but there's really no other way to do it. It would be better if Reliance made a 1/2 inch deeper box or redesigned the plug so wires are inserted from the side instead of the rear. Reliance has a real engineering design flaw on their hands but they probably sell thousands of these and really don't care. Reliance also sells a larger 50amp box, but it's plastic (i think ABS) and I can't see myself installing a plastic box outdoors.
