I have mechanical equipment 277V single phase and disconnect for the mechanical equipment is two pole. Would this be correct?
277 1ph is the line-to-neutral voltage of 480v line-to-line. Thus, with a line-to-neutral circuit, only a 1p disconnect is required.I have mechanical equipment 277V single phase and disconnect for the mechanical equipment is two pole. Would this be correct?

I have 2 pole disconnect 277V 1 ph.
Anywhere in code says 1p disconnect required for 277V 1 ph?
