Seems to be a great interest in electric here and always lots of feedback so figured this would be a great place to ask. I have an existing 200a panel at home and am putting together a plan to build a shop behind the house here in norco ca. Shop will be about 100' away from house. I'm assuming I'll need a 200a panel for said shop. Will have a mill, lathe, large compressor possibly a phase converter ect. 40x 25 building with lighting ect as well. 2 questions with first being is 200a to much for what I'm doing? Second is will I need new wires pulled in from meter to panel to create a 400a deal? Sce is being a bit difficult to get ahold of about this . Waited about 35min to get somebody and had to leave a message.
