Hello all - I’m in the process of rewiring an old cabin and updating the entry service. I’m going more than 6 feet in the house and therefore am required to have a shut off switch outside. The wiring between the meter base and shut off seem straight forward but I’m required to use a cable with 4 wires between the shut off and the breaker box in the back room. I’ll attach photos but if anyone has insight on where the wire that’s not the two hots or neutral should be terminated on the breaker box and the shut off switch that would be a huge help. Thanks in advance.
