Reliance Controls Generators Up to 7,500 Running Watts PB30 30-Amp NEMA 3R Power Inlet Box, Gray

Good quality construction, worked as it should and got me thru two hurricanes so far

Purchased in 2016, so it may be a bit different today. If you use #10 wires, easy—they worked when I tested them. The instructions indicate that 20 ft-lbs of torque are needed on the screws—this could be hard for some people to do with a screwdriver. I used #6 so that I could upgrade the connection to higher amps later if needed. You have to trim the #6 to make it work—the installation instructions indicate max of 8 gauge wire. The box is smaller than some of the other boxes and thus can be a tight fit, but it has standard size knockouts which allows a conduit to be fully attached for weatherproofing. The only thing I have noticed is that the foam seal on the hinged front cover has degraded in the last 9 years. (This is likely due to being next to a heat pump—electric motors emit O3 aka ozone and it attacks foam, etc.). Mine has the standoffs (Bumps or dimples) which offset it from the wall making the cover easier to install. It is a tight fit, especially if you are using larger gauge wiring than the 10 gauge minimum, but it is ‘doable’. Note: If you are DIY with this device, make sure to check local electrical codes. And, most importantly, use a transfer switch or a lockout on the breaker panel. You can kill a lineman working on the power lines if you do not do this. And, there are lots of firefighter made videos of idiots with generators improperly wired causing fires when the power turns back on, fries/melts/boils the generator windings that are sitting below a tank of gasoline. What could go wrong?

We bought a generator to run to our breaker box for when the power went out. I wanted to have the generator setup in the backyard so I could lock our gate and keep the generator safe frombeing stolen or vandalized while running. I bought this so that I could run wire to our backyard to allow our generator to plug in where it eas located which was much cheaper than buying 75 foot power cord to run from the generator to the breaker box. It also allows me to disconnect and put up the generator when not in use.I attached a picture of the current setup. I recently bought a shed though that I am going to setup my generator to run inside it, so I will be moving this to my shed. This will also allow me to plug into this to have power in my shed via an L14-30 extension cord with 4 Power connections. Then if the power does go out, can just plug in the generator and turn off our main breaker to power our house.Perfect for many uses and look forward to our future setup.

I bought this to go with my 7Kw generator and Reliance Controls 30-Amp Transfer Switch Q310C. With a 50 foot run between them I chose to run an 8/3 cable with ground. If you mount this plug against a wall or post as I did, the 3/4" hole is blocked, leaving just the 1/2" one which made getting the four #8 wires inside a challenge. I WAS happy that the connections to the plug accepted this size wire as well and not just 10AWG.Now when the power goes off (a frequent occurrence in my area thanks to AEP), I crank up the generator, run a cord from it to the plug outside my house, flip the transfer switches and the important circuits are running - water pump, refrigerator, freezer, furnace blower, TVs, computers, most lights and of course the wife's coffee maker and toaster oven while the generator runs at barely 50% load. To power the air conditioner would require a MUCH bigger generator so we just turn on fans or run the furnace blower to move the air.One unsolicited comment... For the sake of your local utility worker, PLEASE use a transfer switch be it a smaller one such as the one I purchased or a whole house version. I get really bothered when people write on here how they connect to a receptacle and back-feed their home. That's fine until the day you forget to turn off the main and electrocute the guy trying to get your power back on. I know.... YOU would never forget. Don't be cheap - do it right and you never have to worry.
