Equipment Protection Ground-Fault Interrupters (30mA)

Ground fault interrupters are an effective means of preventing severe electrical shock. A GFI device which protects equipment (not people) is allowed to trip as high as 30 mA of current.

Ground faults occur when the electrical current strays outside its normal path.

To protect against electrical shock, Murray Equipment Ground Fault Interrupters continuously monitor the difference in current between the hot and neutral conductors. If the electricity going to an outlet equals the current coming back from the outlet, the Equipment Ground Fault Interrupter is dormant. If the electricity going to an outlet is greater than 30mA than the current coming back from the outlet, the Equipment Ground Fault Interrupter will open the circuit to stop of flow of electricity.

Technical Data

The Murray 1-pole GFI circuit breaker is to be installed only on a single phase 120/240V AC system.

The Murray 2-pole GFI circuit breaker can be installed on a 120/240V AC single phase, 3 wire system, the 120/240V AC portion of a 240/120 volt, 3 phase, 4 wire system, or on a 208Y/120 volt, 3 phase, 4 wire system. When installed on these systems, protection is provided for 2 wire, 240V AC or 208V AC circuits; 3 wire, 120/240V AC circuits.
