Re: 400 amp single phase service wire size residential
Your electrician or architect / engineer
should must do a load calculation. Due to single phase transformer sizes, most utilities really offer 320A service, not 400A.
This isn't something you take a chance on or get advice from an internet site. Hire someone who knows what they are doing.
