Code Change Summary: Revised code language on GFCI protection for appliances.

In the 2020 NEC^®, the GFCI requirements for dishwasher outlets previously located in 210.8(D) have been relocated to Article 422 (Appliances) and new language was added to point the code reader to Article 422 to find additional GFCI requirements and which appliances require it.

2020 Section 422.5(A) requires the following appliances to have Class A GFCI protection if they are rated 150 volts or less to ground and 60 amperes or less, single- or 3-phase:

(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

2020 Section 422.5(B) details the type and location of the device that provides the GFCI protection as follows:

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

In a nutshell, the first paragraph in new Section 210.8(D) can be summed up as follows:

If any of the seven types of appliances from 422.5(A) do not have GFCI protection as an integral part of the attachment plug, or within the supply cord not more than 12 inches from the attachment plug, or factory installed within the appliance, then either the overcurrent device supplying the appliance must be of the GFCI type or a GFCI device such as a receptacle needs to be installed in the supply circuit.
