Hi I have a 5K generator that I want to connect to my house through the main circuit box in my house.. A friend of mine says there is somekind of on/off box that you connect to open the power coming in then another circuit of some kind the plugs into the generator.. has anybody heard of this? I want this hooked up in case of a power outage and instead of running extension cords through the house I can connect the gen. at the main power box and use the outlets in the house.. makes sense right.. so how do I do it? Thanks Jess
