Ground Fault Circuit Interrupters (GFCI)
Identifying applications:
Used in Siemens and Murray load centers
Definition of product:
Ground fault circuit interrupter (GFCI) is designed to protect against severe electrical shock or electrocution from ground faults. Ground faults occur when the electrical current in an appliance strays outside its normal path, and the human body becomes part of the path through which the electrical current may flow.
Overview of the product:
- GFCIs are installed to protect areas of the home, such as the kitchen, bathroom or laundry, where electrical appliances or products may come into contact with water.
- Current imbalances of 4-6 milliamps or more between load conductors will cause the ground fault sensor to trip the circuit breaker.
Product rating: UL listed, CSA Certified
General features and benefits:
- Available in 1-pole (15-30A) and 2-pole (15-60A)
- Common uses: spas, hot tubs, kitchens, bathrooms, garages, etc.
- Resists false tripping (shielded to prevent RF interference)
- Standard 1 inch per pole format with plug-in design
- Provides Class A GFCI protection
