Do I need 400 amp service? Home Inspection
Oct 29, 2015· Re: Do I need 400 amp service? You can put a 200 amp remote panel in the garage, even a 400 amp remote panel in the garage ... the only issue would be that the service supplying the house and garage is only 200 amp so the most you could get through the service equipment to feed both the house and the garage is 200 amp combined.
