I'm setting a 200 amp panel on a work shop and wiring in a few plugs and lights. The work shop is on a residential property and it is proposed to have it's own meter. According to the utility company it is automatically considered commercial. Which translates to the owner runs conduit and wires from the panel to the utility box at the street. Left for utility to connect. The utility will not size this and says the county inspector will approve/disapprove the installation.

The issue is it is a 375' run. Calculating the voltage drop to be below 3% I'm coming up with 3" PVC sch. 40 and 3 - 750 kcmil wires. Does Table 310.16 and a 3% minimum drop apply to primary wires.

Any suggestions would be appreciated.

Thanks
