So, I'm looking at 2014 NEC 620.51(A) for a wheelchair/platform lift and it says the disconnecting means shall be "an enclosed externally operable fused motor circuit switch or circuit breaker that is lockable open in accordance with 110.25." Then there's an exception for platform lifts that the disconnecting means shall be permitted to comply with 430.109(C) which allows (for motors 2HP and less/300V and less):
1. General Use Switch
2. AC Circuit general use snap switch
3. Listed manual motor controller
My question is, why wouldn't a non-fused safety switch be acceptable?
Thanks in advance for any input!
