Perfect for a permeant connection
By James H 
Texas
Purchased 02/24/2023 | 
Review Posted 03/20/2023 
I wired up a manual transfer switch with this outlet so my wife and son can easily get power when we lose it at the house, which is a few times a month. Great product, easy to install. Exactly as described. I would recommend this product.

Your Description includes Twistlock and More info

Review Posted 01/27/2023 
Better job of describing than Generac or other ads I found. Your info includes Twistlock, Durable, Glass-Filled Nylon NEMA 3R Enclosure, 50A 125/250V male inlet in NEMA configuration CS6365 on bottom. I bought a Twistlock cable on Amazon and electrician used this box with a bottom plug in. Kind I wanted! bit worried about sunlight damage to the plastic eventually.

Works Well, But Pricey For What You Get.
By Fred W. 
POWELL, Ohio
Purchased 02/24/2021 | 
Review Posted 03/31/2021 
I like that it has a receptacle in the bottom. The challenge is this is just a plastic box with a $20 panel mount inlet connector. Very over priced and within Generac name I thought it would be better quaility. So you are paying double the price just for the name. However, while I’m not crazy about the part the company shipped very quick and has a good system. I’ll buy from them in the future.

Have only used it once to test it so far, seemed to be fine. The electrician who installed it thought that it was well built

No Rubber Flap
By Merrimac Cattle Co 
Geyser, Montana
Purchased 10/19/2018 | 
Review Posted 11/10/2018 
Received an email for this box being a replacement with the only difference from what it replaced was a rubber flap for the plug instead of metal. There is no flap.

Tough to get plug in, see detailed review
By Edward T. 
Malvern, Arkansas
Purchased 12/10/2016 | 
Review Posted 01/02/2017 
In order to use the Generac cable, you have to tilt the plug at about 10 degrees, push in and straighten as you push.
It's a little hard, but once you push it in and twist it several times, it's easy after that.

My take
By Mike 
New Jersey
Purchased 12/29/2012 | 
Review Posted 02/25/2013 
Am using this product to bring emergency power into my house. Looking back I wish I would have gone with the metal box hoping it would be a little sturdier. The 50 amp cord is very substantial so when you attach it engaging the twist lock it feels like you are gonna rip the plug from the plastic box body. Do yourself A favor and ditch the included 3 screws and put in small bolts with locking washers and thread lock. This helped sure up the installation. Also mount the plug high so you can visually guide the large 50 amp twistlock plug into the receptacle. I like the plastic box but I think they should make it of a heavier schedule material. Good luck.

5o Amp Inlet Box
By Tony 
New Jersey
Review Posted 01/02/2013 
The price was right, delivery was quick, and the box had plenty of room to hook up 6 gauge wires. Tough to work with, but all went well and works properly. All set for the next power issues.
