Ahhh yes...dread power going out. Welll thats what the generator is for, have all the heating controls,pumps, etc wired into one junction box, main power line from servie panel has a 25A male plug end into female outlet on box, power goes out, undue power line plug at junction box, put generator lead on it, and alls good. I always keep fimgers crossed power won't go out. Generators under deck coal boiler room is on, lead is hanging in boiler room by junction box. Now if generator don't work, i will be in deep stuff.
