GFCIs protect against electrical shock that result from ground faults. Ground faults occur when electrical current in devices stray outside of its normal path. A human body can become part of this circuit, which results in an electrical shock. GFCIs analyze the amount of current entering and existing from the circuit and will trip when the difference is greater than a certain value.
Siemens GFCI circuit breakers are UL Listed and CSA Certified as Class A devices. Current imbalances of 4-6 milliamps or more between load conductors will cause the ground fault sensor to trip the circuit Breaker. Note: A load neutral is not required on the circuit. However, the white line neutral (pigtail) must be connected to the panel neutral for the device to function. The Siemens 2-pole GFCI circuit breaker can be installed on a 120/240-volt AC single phase, 3-wire system, the 120/240-volt 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, 240-volt AC or 208-volt AC circuits; 3-wire, 120/240-volt AC circuits. The Siemens 1-pole GFCI circuit breaker is to be installed only on a single phase 120/240-volt AC system.
Siemens GFCI plug in circuit breakers are intended for use in Siemens EQ, Siemens Ultimate, ITE, and Gould load centers or meter combinations. The double pole Siemens breakers may be used in 1 or 3-phase load centers and are 240V rated. To ensure the warranty on a Siemens panel is not voided, the use of Siemens breakers is required. The GFCI is intended for areas required by code to have ground fault protection, such as bathrooms, kitchens, and outdoor circuits. Check with your local electrical inspector to confirm. The use of a double pole AFCI allows for shared neutral applications in which two circuits will share a common neutral.
