Gen-Tran 50-Amp Non-Metallic Power Inlet Box w/ Flip Lid

I had this inlet box professionally installed. I did, however, open the box and inspect the insides upon arrival. It's a tight fit inside the box and the heavy gauge wire requires muscular fingers to install the conductors.

Take your time and you'll get it wired. After the electrician had the inlet installed, I tested the fit of the 25 foot, 50 amp generator cable (Generac part #6389). The first try the fitting was very tight and took quite a bit of work to get the plug to go in the socket.

I had to get on my knees and carefully study the fit. I took my time and didn't force anything. I finally got the plug in place and turned (locked into place). I then repeated the process about 5 more times and soon the plug was sliding right into place with little difficulty.

If you need a 50 amp power inlet box, this is the one to get.

Works as planed.

Just installed the gen tran 50amp inlet outlet. There is plenty of room in this enclosure to wire the outlet. Nice unit. Highly recommend this to anyone. As long as you take your time and keep wires neat there is no reason why you would run into problems with the install. I give this 5stars and two thumbs up.

As another review said, it is very tight in there for the wires. The inlet model I have ending in a 4, (model 64654) requires you to take the connector and the flip cover off, wire it, and reassemble with 3 screws in the bottom. Getting the 3 screws back in the threaded holes was tough. I had to take the unit off the wall, and brace the top of it against the house to get the 3 screws to go back in. If you have no other choice than this inlet box, be sure to trim the wires back as much as possible so you don't have to fight their spring tension.

The real problem came when I went to go plug the female end of the 50 amp generator cord into the inlet box. Try as I might it would not go in more than about 1/2 inch, and was not making a connection. I called Gen Tran and they said you really have to push it in hard to get it in. I made sure that the wires were not affecting the connector - they were pushed in and dressed adding no tension. Ultimately what I had to do was take the inlet box off the house again and brace the top of the box against the side of the house, and hit the end of the female connector 6 times with a hammer. I was happy to see it finally go in, but then it was so tight that it wouldn't even twist. So I am concerned how good a connection this is making. I fed current out from my panel, and I get proper voltage readings at the other end of my generator cord, but under load I wonder if that connection will heat up because it didn't twist like it's supposed to. But I figure it will get me through this winter until I can replace the 50 amp inlet box with another model.

The connector is in so tight that I just left it in there, and coiled the generator cord and put it in a contractor bag on the side of the house. But this is not doing what an inlet box is intended for. That's the connection that you want to make and break easily, and if anything leave the other end of the cord (in my case the straight blade 50 Amp connector) plugged into the outlet of the generator. On the Generac GP17500E the connector is on the bottom of the panel, so I'll be probably laying down in the snow to connect it. My original intention was to leave that connected and store the cord on top of the genny under its storage tarp. Ideally it's best to keep the cord indoors, though, because when it's very cold it's going to be hard to unbend that 6/4 SOOW cable.

In conclusion, if you are desperate for an inlet box, and this is the only one available you can make it work, but the design is just not the best. Gen Tran, to its credit, took down my comments so maybe it will affect other designs.

The Generac GP17500E Generator, by the way, assembled and started up like a charm. And it wasn't even very loud considering how powerful it is. Be sure to put in the foam pre-filter over the paper air filter, and provide a good ground for the genny. I found a nice 8' long copper coated grounding rod (a.k.a. electrode) at Home Depot for $11 and a brass clamp that fits on it with a screw connection for the ground wire.

This product was easy to use. The plugs connections are color coded. All you need to do is strip the wire, insert in the appropriate color and screw down. For a 50 amp connection you are using 6 gauge wire so don't keep the wires too long and you'll have plenty of room in the box without issues.

There is not enough room in the box for the wiring. The box needs to be several inches taller.

We were very disappointed that we could not get the old Midwest version that we used to get from you, there was a lot more room for the wiring.
