Question:
Can sheet metal screws be used to connect grounds to the metal of a fluorescent light fixture? We've been doing this for years, but an inspector has called us on it. Is there a rule?

A

Hi Chris, thanks for the question!
We hear that a lot and unfortunately, "We've been doing this for years," doesn't make it right, or Code compliant.
The NEC does not permit bonding or grounding connections to be accomplished using sheet metal screws. See Section 250.8(A) for a list of methods permitted to make such connections.
