All internal AC power wiring is factory installed. The AC Load Center receives 120-volt,
60-amp service from the local utility, hard wired into the AC Load Center via a 30-amp supply
side main circuit breaker. The AC distribution to cabinet AC loads is via four load side circuit
breakers The AC Load Center has capacity for eight circuit breakers.
The AC circuit breakers installed in the AC Load Center are sized according to the current
requirements of the equipment in the circuit. In the event that any breaker becomes defective
