If I have a 480/208V transformer installed above a lay-in ceiling, I'm I required per code to provide a non-fuse disconnect switch on the primary side even though the primary conductors are protected by a circuit breaker in a panel that is not within site? If so, does the disconnect switch need to be located within 6'-7" AFF or can I mount in adjcent to the transformer above the layin ceiling?
It's a grocery store and the 480 Volt panel that is feeding the transformer is on the other side of the building. The primary conductors are protected by a circuit breaker in the 480 Volt panel. The 208 Volt panel has a main cirucit breaker.
