We are preparing to start building and are doing a lot of the work ourselves. I am planning to trench, lay schedule 80, & pull the service entrance myself. This will be about 300ft. If I read the NEC correctly it looks like I need USE 2/0 cable for a 200a service. Is this correct? I will hire an electrician to make all connections, but I can pull cable as well as the next guy. Termination of the conduit will be at the disconnect box on one end and the generator ATS on the other. Are there any other items I need to pay attention to on the schedule 80 conduit?
