Multipole Breaker Protecting 120V Circuit

[vw55]

I've had a request to add a receptacle at a 208V single phase HVAC unit that is protected by a 20 amp 2 pole circuit breaker. The contractor wants to pull in a neutral conductor from the serving panel and extend one of the HVAC circuit phase conductors along with the neutral to the 120V receptacle mounted on the unit. He says the 20 amp circuit breaker is protecting both of the circuits. Anything in the code that will not allow this?

210.4(c)...

Take a look at 210.63, especially the last sentence

210.63 appears to apply to the receptacle required for servicing the unit. The contractor is wanting to install this particular, single receptacle at the unit to power a cord and cap connected condensate pump that will serve the unit. Wouldn't that be a different situation?

It appears 210.4(c) exception no. 2 would allow this. Am I right?

Just install a 208/230 v condo pump. No new circut needed.

We do it all the time here. I've never had a problem.

This is a small pump, specified by the mechanical engineer. It's evidently not available in 208/230V.

210.63 Heating, Air-Conditioning, and Refrigeration Equipment Outlet.
A 125-volt, single-phase, 15- or 20-ampere-rated receptacle outlet shall be installed at an accessible location for the servicing of heating, air-conditioning, and refrigeration equipment. The receptacle shall be located on the same level and within 7.5 m (25 ft) of the heating, air-conditioning, and refrigeration equipment. The receptacle outlet shall not be connected to the load side of the equipment disconnecting means.

Is this what you are looking for?

I don't think this would be any different then the receptacles installed for a humidifier or electronic air cleaner at a furnace, we do it all the time, and I would go one more since it is being protected by a 20 amp breaker, install a 20 amp rated single receptacle to the load side of the contactor if the pump is only required to run when the unit is running, this way you only need to run a neutral conductor, if this is outside putting it inside the unit will avoid having to GFCI it, also. we have installed case heaters like this for outside compressors like this, but we put them on the line side of the contactor.
