What is a GFCI
Residual-current device
A residual-current device (RCD), or residual-current circuit breaker (RCCB), is a device to quickly disconnect current to prevent serious harm from an ongoing electric shock. Injury may still occur in some cases, for example if a human falls after receiving a shock.
How to provide GFCI protection to an outlet?
You can, provided that:
- The GFCI device is “upstream” (toward the circuit breaker) from your regular outlet, and
- The GFCI device is designed to protect “downstream” (away from the circuit breaker) devices, and
- You wire both the GFCI device and your outlet correctly.
What is GFCI outlet is and what does it do?
GFCI outlets are the electrical outlets with a test button and a reset button, often with a green indicator light.
