Am I misinterpreting the code?

[cwsolo]

Got a call from an inspector today he said that the air handler I wired does not have a disconnect. I stated that since it was put in a small interior closet in an old house and there was no room for one that would have working clearance that I special ordered a GE breaker padlock lockout device that is permanently installed in the panel on the breaker so that the breaker can be locked in the off or open position. He asked where I heard that it was legal to do this? I told him I read it in the NEC, and after finding the article cited 424.19 (A)2(2) He said that did not apply and that was intended for commercial locations where supplemental heat strips are installed downstream in duct work!?
Am I wrong I just want to know, Iv'e done 2 jobs this way now and only had trouble on this one but thought this was a legal install.?!

As long as you meet one of the requirements of (1) - (4) in that section, it should be approved. The inspector cannot assume intent nor enforce preference. We have this same issue with several builders in my jursidiction. Some opt for a unit switch (breaker), others install the lock-out device.

If you are talking about an air conditioning air handler or a heat pump, I believe 422.31 applies. It is not fixed electric spsce heating equipment - it would be central heating/ and or cooling which is covered by 422.

422.31(B) is very clear, and you are permitted to wire it as you did.

I believe that 422.32 applies here, in which you are not permitted...unless the fan motor on an air handler is less than 1/8 hp?.are they?, never looked.
