Sorry this isn’t directly smart home related, but there seem to be a lot of electrically inclined folks here.
Without removing an overhead light fixture, is there a way to confirm the fixture is properly grounded? I know generally the wiring is 14-3 or 14-2 in the house with bare grounds, but would like to make sure the ground hasn’t become disconnected. I have regular bulb fixtures and integrated LED board fixtures.
For the bulb fixtures, can I turn off the breaker and check continuity between the metal part of the fixture and the neutral part of the bulb socket?
