Can a 3-way switch set serve as a disconnect for a small exhaust fan?
Since the code allows (225.38 exception) 3-ways for a residential garage disconnect, it would seem ok to do the same for the exhaust fan. Yet, it seems a bit dangerous to rely of turning off the circuit with a 3-way, and hoping that someone doesn't come along and flip the out-of-sight switch while you are working on the wiring.
