2020 NEC Change:
422.5(A) General. Appliances identified in 422.5(A)(1) through (A)(7) rated 150 volts or less to ground and 60 amperes or less, single- or 3-phase, shall be provided with Class A GFCI protection for personnel. Multiple Class A GFCI protective devices shall be permitted but shall not be required.
(1) Automotive vacuum machines
(2) Drinking water coolers and bottle fill stations
(3) Cord-and-plug-connected high pressure spray washing machines
(4) Tire inflation machines
(5) Vending machines
(6) Sump pumps
(7) Dishwashers
Informational Note: Section 210.8 specifies requirements for GFCI protection for the branch-circuit outlet where the covered location warrants such protection.
422.5(B) Type and Location. The GFCI shall be readily accessible, listed, and located in one or more of the following locations:
(1) Within the branch-circuit overcurrent device
(2) A device or outlet within the supply circuit
(3) An integral part of the attachment plug
(4) Within the supply cord not more than 300 mm (12 in.) from the attachment plug
(5) Factory installed within the appliance.
Rationale:
The requirements in 210.8(D) and 422.5(A) brings much needed correlation for GFCI protection while bringing consistency with future additions of the code as it relates to modifications of the list of specific appliances that require GFCI protection. It also provides the type and location of GFCI protection for appliances. The GFCI protection of dishwashers is still required but has changed from just dwelling units to all dishwasher appliances now. It is important to note that the requirements in 422.5(A) are for 60 amperes or less, single- or 3-phase and 150 volts or less to ground. Sump pumps were also added to the list as in the previous code, they may or may not have been required and was dependent upon the location of the sump pump. The requirement of “provided for public use” was removed for automotive vacuum machines and tire inflation machines so that now they are required to have GFCI regardless of their location.
