Ground-fault protection of equipment is not permitted for fire pumps supplied by a feeder over a certain size, which includes a 1,200-ampere breaker. The National Electrical Code (NEC) specifies that ground-fault protection cannot be used on fire pump circuits. Fire pumps must ensure operational reliability in emergency situations, and the introduction of ground-fault protection could interrupt service when it's critically needed. Therefore, for a 480-volt fire pump supplied by a 1,200-amp breaker, ground-fault protection is not allowed according to standard practices and codes governing fire protection equipment.
