Read the reviews and the problems of getting the 10 gauge wire into the box. We had no problems. Good quality plug and cord is heavy duty. Very happy with this purchase.

This kit is fantastic. The price is phenomenal and the quality is great. The cable is very heavy duty and they offer it in every size you could need. The inlet box is also constructed very well. Both ends are twist lock, with an additional screwing collar on the inlet box side, the screwing collar is the weakest point of the kit but it's just an extra precaution, it still functions as it should. If I ever have another need I will 100% purchase this kit again.

Purchased it for my generator temporary power. Looked at reviews and decided to order it. I have installed it and haven’t used it under power yet but am satisfied with delivery, ease of installation. It appears to be heavy duty and well built. And the price of the package is good. . I gave it 4 stars because I haven’t tried it yet but if it performs as well as it looks I give it a 5 star. I intend on ordering another after I operate this one under a load.

The box was an easy install. Plenty of room in the box for wire routing. Comes with mounting screws to mount on wall. The plug in the back has places to slit the rubber/plastic to slide the wiring though. Would recommend this to anyone installing a 240V 30A generator for the house.
