Electrical Wiring in the Home/Question on wiring a bathroom exhaust fan.
I am replacing my bathroom exhaust fan w/light.
The new fan is the Panasonic whisper green model.
It can run continuously on a low speed and then increase
when the switch is turned on.It also has the nice feature or running for a predetermined time after the switch is turned off. Of course this now requires an additional switch wire. Trying to fish a new wire may not be possible.I maybe able to power the new fan form a different circuit in the attic. My question, is it possible to use the common wire (white) from another separate circuit?
This would then free up a hot wire (black) and the common wire (white) that I could then use as my switch leg. Is this possible ? is it code ? Let me know as well as any other suggestions.
The only legal way two circuits on a single phase circuit can share a nuetral is for all of the circuit wires be ran together, either as a single cable or in conduit with all circuit conductors in the same conduit, so even circuits that may work in theory they are not legal. Thanks J
