680.12: Pool equip multiple disconnects .....?

[brantmacga]

680.12 says that "one or more means to simultaneously disconnect all ungrounded conductors for utilization equipment other than lighting ......"

I've always interpreted this to mean that you must have a way to disconnect every pool pump with a single disconnect. Is that correct?

Went to wire a commercial pool today, and the project electrician had provided one single phase feeder for a pool panel to operate a single phase 2HP pump and lighting, and they provided a separate 3-phase circuit in another conduit for a continuously running 7.5HP pool pump.

The pool panel sits next to the equipment pad and has breakers for the 2HP pump and lights; the 3-phase pump circuit comes from a sub-panel about 30' away. I brought this up with the pool contractor, and they indicated to me that the project drawings showed this setup. The sub-panel that has the 3-phase pump circuit also feeds the 3-phase pump, so would the MCB in that panel count? My concern was having those two panels separated that far but both feeding equipment on the pad.

I think it would be better if the disconnects were grouped, but the NEC only says it has to be within sight, which is defined as within 50'. So, I think your install is legal, maybe not the best design but legal.
If I read your description correct that is!

In my opinion no.

I think what's throwing me here is the exception for lighting. In my mind, I viewed the scenario to be all pumps must be able to be disconnected by a common disconnect, with the exception for lighting allowed because it could come from a different panel. I couldn't think of another reason as to why the exception for lighting is there. Thoughts ?
