electrical wiring for furnace
I have a gas furnace that uses 120 v, 6-7amp of current. Currently, the wiring is the following: a (dedicated circuit ) power line is connected to a receptacle mounted on the side of furnace. the furnace is hard wired to the back of the receptacle, the condensation pump is plugged into the receptacle.
I am thinking of getting an 14 gauge electrical cable, put a three prone male plug on each side. And when we have power outage again during the coming snow storm, I can plug one end to the generator, and the other end to the the receptacle to provide electricity to the furnace. (I believe condensation pump is not used with furnace.)
I will be sure to turn off the whole house circuit breaker switch and the circuit breaker for the furnace so no electricity from the generator will back feed into the house.
I have a 7000w generator, but I didn't get around to have an electrician to put a transfer switch or interlock in. So I couldn't run furnace. During last week's ice storm, we were out of power for 4 days. the house got to as low as 38 F. Now we have another huge snow storm coming. I am hoping this set up can run furnace temporarily .
Can someone give me some feedback whether this is doable? Any danger I didn't think of?
I will only do this as the last resort, of course. And as soon as this is over I will get an electrician to install the transfer switch or interlock properly.
I will appreciate any feedback. Thank you!
