Ground Fault Circuit Requirements

Aug 6, 2021

Each code change cycle more and more movement towards whole house GFCI protection occurs. The 2020 NEC is no different. In the past, GFCI protection in dwellings was required for 125-volt, single-phase, 15- and 20- ampere receptacles in specific locations. This cycle removes “15- and 20- ampere” from the text and expands GFCI protection in dwellings to include receptacles up to 250 volts such as the typical range or dryer receptacle, but only if these receptacles are placed in specific locations. Most dwelling unit kitchens have a cord and plug connected, 240-volt oven/range but the receptacle for it is not installed to serve the countertop, therefore it would not require GFCI protection unless the receptacle is installed within 6 feet from the top inside edge of the kitchen sink bowl.

All 120-volt through 240-volt receptacles installed in the locations specified in 210.8(A)(1) through (11) & supplied by single-phase branch circuits rated 150 volts or less to ground shall have ground fault circuit interrupter protection for personnel.

Below is the new code language for the 2020 NEC that increases costs with the residential electrical contractors;
