This is a good quality inlet box. I like how it is made out of steel rather than plastic. Installation was moderately difficult mostly due to the monster romex that is required. I used a step drill bit to drill a hole in the back to route the 6 gauge romex through with 3/4” cable clamp. Working with 6-3 romex plus ground is challenging since it is so stiff and heavy. There’s plenty of room inside the box to make the wire connections with blue wire nuts. The only issue I had is the lower mounting holes are blocked by the inlet connector body. The workaround was to drill two new bottom mounting holes closer to the edge of the box. I attached the inlet box to the brick wall with Tapcon screws. I like how the inlet cable connector attaches to the bottom of the box, which provides rain protection. Works great with my Firman tri-fuel generator and Champion 30 ft, 50 amp power cable. For safety, I installed a generator breaker interlock model BR-200-2 from Generator Safety. The interlock is a crucial safety mechanism that prevents the main breaker and 50 amp generator breaker from being on at the same time. I can power my whole house off natural gas except the central HVAC. That’s okay because when the power is out I can use my window ac or space heater instead.
