Wiring around the Main Circuit
Wire Size, Terminal Screw, Screw Tightening Torque, and Molded-case
Circuit Breaker Capacities
For the main circuit and ground, always use 600-V polyvinyl chloride (PVC)
cables.
If any cable is long and may cause voltage drops, increase the wire size
according to the cable length.
