Any input would be greatly appreciated. Regarding 422.12 - we are wiring furnaces and we are using the existing dedicated circuit from the old furnace in residential apartments. there is a condensate pump being installed that plugs in. according to 422.12 exception #1 we can install a receptacle tapped off the same circuit as the furnace for the condensate pump that plugs in. (we installed a duplex receptacle next to the service switch - in a utility closet not requiring gfci protection)
The question is - does this have to be a single receptacle or is a duplex receptacle a legal installation? I have an inspector telling me that I have to install a single receptacle because there will be a receptacle not in use which makes the circuit not dedicated. Further more - in a basement I would have to use a duplex gfci receptacle because I don't think a single gfci receptacle exists.
I think he is over reading into the actual intent of this code. He claims that leaving an open receptacle - someone could come along and plug something else into it. well, you could simply unplug the condensate pump and plug anything into that as well.
It is my opinion that the code does not address this issue therefore it is a legal installation.
He then told me to cut off the plug on the condensate pump and hard wire it or put silicon over the unused receptacle so no one could use it. I think both of those suggestions void the ul listing of those products.
If I installed a sticky label that read "receptacles for heating equipment only" would that then satisfy anything?
