An electrical schematic shows a 400A main circuit breaker panel H1A and a 225A main circuit breaker panel H1B connected to lighting control panel LCP1. Power is stepped down through a 75 kVA three-phase four-wire dry type transformer designated X1B with a 480V primary and 208Y/120V secondary. The transformer features a minimum impedance of 2.5 percent and feeds connected loads with circuit protection.
