Thanks that sounds good to. I have another question I tried to do my homework before spending money but I jumped and bought cable to hook up my generator and now I am second guessing myself I got 10/3 direct bury wire for my me 802 figuring 30 amps is this OK or should I have jumped up to 8/3 any thoughts? And does anyone know the correct way to hook the wire into the lugs?
The best answer is.. It depends..
It depends on the length and how unbalanced the load is in your house. My main fear with home backup generators is how many 120v loads are there which increases neutral current. Most cables have neutrals the same size as the load conductors and some have undersized neutrals. I try to avoid those cables for generators if I can and I pull THHN-2 wire in conduit. That will reduce voltage drop when you have a lot of 120v load on the generator. In my case I'm using a #6 SOOW cable and I manage my loads to minimize the neutral current.
#10 is fine for balanced loads if you keep it under 50-75'. For runs over 75' I go up one wire size to minimize voltage drop when you are running higher loads.
Then there is the issue of grounding.. I do hope that is a 10/3 with ground. If not I would recommend returning that cable and buying one with a ground. You will need a ground wire to correctly connect a generator to a home.
More than anything be sure to talk to someone local regarding any special codes for connecting a generator.
