to share a neutral or not


I am installing a ceiling fan and lite in a stairwell, lite and fan on seperate swithches using 14 gauge wire should I run 1 14/3 and share a neutral or should I run 2 14/2 wires, the light will be on a 3 way switch at top and bottom of stairs and fan will only be controlled and top of stairs, and they will get power from seperate lighting circuit with only lites on the circuit any help would be great

thanx

Sure, share it. This is not the same kind of neutral sharing that occurs between two different circuits, so you are fine.

I think you need to reread the post.
He said seperate lighting circuits.
If two circuits, then you can not share the neutral!

I think it is clear that he is bringing power to the switch box from a single lighting circuit. His concern is the 14/3 to the fan having only one neutral for the fan and dome light. I don't think he is talking separate light not that it would make any difference. It's no problem as I see things. This is always done with a 14/3 to the ceiling fan from the switch box. I think this is reasonably close to what he is asking.

To minimize confusion there should be just one hot feed for the fan/light unit coming to the switch box or fixture box whichever is applicable. Even though they may be on the same circuit now, two hot feeds arriving in the same outlet box should not have their neutrals tied together as some day the feeds may be moved to different circuits.

When the fan/light unit has only one neutral coming out of it, the fan and the light may never be powered by different circuits. Using the 14/3 cable down to the switch boxes and power feed, the correct connections are assured since there is just one white wire in the cable to connect the fan/light unit to.
