adding a feed to a bathroom exhaust fan off of existing light circuit that runs throughout the house , new wiring is all inside bathroom does this need to be arc-faulted

thanks rob
 
thanks one more question what if switch is on the outside of the bathroom wall and circuit feeds other devices
Thanks again
 
If that circuit is supplying outlets in an area/room which is on the afci list, and you extend it more than 6 feet, it has to be afci protected.

It doesn't matter what kind of area it gets extended into. If it's supplying a living room, bedroom, hallway, etc, and you extend it more than 6 feet.....it doesn't matter if you're feeding an area not requiring afci protection (garage, outside, etc). You still have to afci protect it

I agree. I must have misread the question the first time around.
 
Thanks I have quite a few bathroom exhaust fans to replace the new ones require a 14/3 one for the light and one constant feed for the fan to run all the time and a new 14/2 for high low speed there usually is either a 14/2 or 14/3 already there so i would use that then technically i would be adding switch legs so I'm thinking that will also be considered an extension of the circuit ? Thanks for your input

The less than 6' extension exception just says 'branch circuit conductors' so you're right, it doesn't matter if its switch legs or power.
