Abstract
A ground fault and fire detector system for an A.C. electrical power distribution apparatus including a multi-pole circuit interrupter to disconnect a poly-phase electrical power supply from a load. A single-pole circuit device is operatively connected to the circuit interrupter for controlling its operation. Ground fault sensing circuitry is operatively positioned with respect to at least one wire for initiating a fault current. The single-pole circuit device is responsive to the fault current for activating the circuit interrupter to disconnect the power supply from the load.
