First time ever seeing this. Ran into a switch labeled as the emergency cut off switch for a gas fired furnace. The switch was in a double gang box with a GFCI outlet. Anyone know the rules on this. Thanks
Never heard it called emergency switch.
I know the air handler requires a ‘service switch’ to be located in sight of handler.
If the Furnace and GFCI are in good working order, there should be no problem with that setup. Mine is on a GFCI.
Larry, does the switch need to be labeled though with a red gas burner emergency off cover plate? Like this one?
Mine isn’t and it is only 8 years old.
Got it. I for some reason thought they were required to be
There is an emergency switch and then there is a service switch, the two are not the same. Oil burners require an emergency switch, gas units do not (unless it’s a local thing).
Yep, Simon, it was a gas furnace. But, good info. Thanks.
Thanks, Simon. Here in NE Oklahoma, I have never seen an oil burner.
You guys mostly Propane or Natural Gas out there?
Natural gas and electric in towns. Rural areas use propane and electric.
A furnace requires an individual branch circuit that can only feed equipment related to the furnace. A Decora style switch cannot be used as a disconnecting means because it is not marked to the indicate On/Off. Why is the furnace cord and plug connected?
Good info, Robert.
Why is the furnace cord and plug connected?
I have never seen them in a double gang box before, usually the furnace shut off is directly on the furnace or nearby like this one but in a single gang and clearly labeled . But if lets say the humidifier was plugged into the outlet it would be ok because its part of the furnace equipment? Just the decora style switch would be wrong. Am I understanding this correctly
Keep in mind that many (older) systems have been converted from Fuel oil to NG/LP, thus this may be a carryover from that conversion.
