I have a 150 amp switch by the meter at my house. My meter is too far from my service panel that's why I have a switch outside. There is a 50 amp service panel in my detached garage fed by a 50 amp breaker in my house service panel.
I was thinking about putting a 50 amp generator inlet socket in my garage and putting a lock on the outside 150 amp switch with the key to the generator in the switch box. Then if I need to use the generator I would unlock the 150 amp switch box and turn off the breaker get the key to the generator re-lock the box then go into the house turn off all my service panel breakers. Then go out side and plug in the generator start it go into the house and turn on the 50 amp breaker to the garage and then select which breakers I need in the house.
I have had one electrician to my house to quote a inlet to my house and a interlock on my service panel. He didn't seem too interested but said he would email my a quote. I have contacted another contractor but he hasn't call back yet. I want to eventually have it done right but want a temporary solution, if needed.
