Feb. 5, 2020

Test your NEC knowledge.

Q. In general, when does the Code allow flexible cords to be used for the connection of appliances?

See the answer below.

A. As outlined in Sec. 422.16(A), flexible cords are permitted to:

(1) Facilitate frequent interchange, or to prevent the transmission of noise and vibration [Sec. 400.10(A)(6) and (7)].

(2) Facilitate the removal of appliances fastened in place, where the fastening means and mechanical connections are specifically designed to permit ready removal [Sec. 400.12(A)(8)].

Flexible cords aren’t permitted to be used for the connection of water heaters, furnaces, and other appliances fastened in place, unless the appliances are specifically identified to be used with a flexible cord.
