Explain the operation and need of a ground-fault circuit interrupter (GFCI) and also mention the area that requires GFCI.
Explanation of Solution
Discussion:
A device that senses an unbalance current flow is ground-fault circuit interrupter (GFCI). When a ground fault exists in a circuit, an unbalanced current occurs. This type of current flow may cause death or injury to a human being. The flow of unbalance current is stopped by GFCI. When the value of current exceeds
According to an article NEC 210.8, a 125 volt single-phase 15 and 20 amperes branch circuits require a GFCI protection at specific location such as kitchens, bathrooms, outdoors, garages, and within
Conclusion:
Thus, the operation, need and the area that require GFCI are explained.
