National Electrical Installation Standards

Standards as High as Your Own

Wednesday, August 25, 2021



As part of a retrofit project, we will be installing LED round high bay fixtures. The fixtures are furnished from the factory with a loop and 6’ cord. We will install a hook to provide fixture support attached to the ceiling structure at the desired fixture height. A j box will be installed directly above or adjacent to the new LED. The entire factory supplied cord will be visible. Connection to the j box will be made using a cord grip with strain relief provisions. We will also use a disconnect type connector to splice the cord. I believe this method is in compliance with 2020 NEC ART 410.62 Cord-Connected Lamp holders and Luminaires. A fellow electrician does not agree and claims a twist lock cord cap and receptacle are required to meet code. Please enlighten.

Thank you,

Dan Collyard



Hello Dan,

Based on the information in the question, an attachment plug and receptacle should be installed for these high bay luminaires. The requirement comes from Section 410.62(C)(a). List item (b) would be applicable if the installation included a canopy and was in a suspended ceiling. Hope this is useful.
