I just bought a new home in NE Pa. It's about 4 years old. Just inside the kitchen coming in from the door of the attached garage is an on/off switch with a bright red cover plate. I'm assuming it's the safety switch for the furnace to turn it off in an emergency. The furnace is gas/hotwater.
When the furnace is running and I flip the switch, nothing happens. The furnace keeps running. I checked in the basement and just below where the switchplate is located, exiting from the corner of the base stud plate is about 10 feet of coiled 14/2 wire just hanging there. On it in ink is written "furn safety". But it's not connected to anything.
Was this an oversight on the part of the builder/electrician? Or did it suddenly become a non-code item? I find it hard to believe than an inspector would miss it.
If this must be hooked up, how do I go about doing it? Just finish the run to the power near the furnace and splice it in so that power runs to the furnace only when the switch is turned on and the circuit is complete?
Or just forget the whole thing?
Thanks.
