A few of us were discussing the proper use of generators over in Electrical and a question came up that you all in HVAC might be able to answer.
Is there a NEC code that addresses if a gas furnace electrical supply consist of a properly size cord plugged into a dedicated outlet?
Currently my own furnace is hard wired into a receptical that has a hot outlet as well as a switch to cut the power to the furnace while being serviced.
The reason for asking is when using a generator supplying power to different appliances by extension cord ... the furnace can then be unplugged and plugged into the extension cord with power from the generator.
Thus the question regarding the NEC code (where a copy is hard to come by for the average homeowner).
We all would welcome your thoughtful suggestions and advise...
Thanks redline. I have a copy of the NEC 2005 code book but it really does not say for sure one way or the other...it leaves it up in the air. I will leave it hardwire and research more into properly using a transfer switch at a subpanel.
