What is Changing?

NEC 2020 code changes look to set new standards in GFCI protection

During the recent 2020 code review, panel members of the National Electrical Code (NEC) approved changes to ground fault circuit interrupter (GFCI) protection. Those changes dramatically reduce the dangers associated with electrical hazard and shock. The most significant change is the increase of amp protection ratings across all receptacle outlets, both indoor and outdoor, wherever GFCI protection is required.
