Is this the correct setup to hookup generator?
I am planning on hooking my 5500 watt generator up to my house. I have a 200 amp main breaker ge panel in our utility room. Hd sells an interlock kit for it. I'm going to install a 30 amp two pole breaker for the backfeed from the generator. I am going to run about 50 ft of 10/3 romex w/ground from an inlet box with watt meters in our garage between the inlet box and main panel and then use a pre-made 10/3 twist lock male to female extension cord made to go between the gen and inlet box. Is this the correct way to do this? Is the breaker on the generator acceptable for over current protection on the 10/3 from generator and the 10/3 romex in wall between inlet box and panel or should I purchase inlet box with a built in 30 amp breaker. The 30 amp plug on the gen is not gfci protected. I plan on turning off all non essential breakers in main panel and monitoring load with watt meters. Thanks in advance for any help.
