I have a 60x100 metal shop and I want to put in a mechanic's shop. it has and existing 120/208volt 3phase meter and disconnect only. I want to install a 200amp 42 space panel, it has 8 car lifts that I want to run 4-40amp circuits and tap 2 lifts off each circuit. 5 ton A/C 11- high bays a misc outlets. it has a 2 story office about 800 SQ-FT. just the minimum basic to get by. I can provide all the info. the city of Springfield needs and engineered plan with a stamp on it.
