The Ground Fault Circuit Interrupter Switch (Shoremaster Part Number: 1014467) is also known as GFI or GFCI. This essential electrical outlet is designed to protect against electrical shock. GFI is required in most states, and upgrading to GFI outlets is highly recommended for homeowners. The Ground Fault Circuit Interrupter Switch is a reliable and advanced solution that safeguards you and your family from potential electrical hazards. It monitors the electrical current flowing through the circuit.
