In regards to 3 way switches, if I am wanting say 3-4 potlights to be on that 3 way, is there a wiring option I must use? I intend to have a 3 way switch at the top of the stairs with 14-3 going from it to a 3 gang where the feed is and the other 3 way switch, and from there to the potlights.
I did about 6 months apprenticing where I did this quite frequently but it seems to have left me.
Nowadays the best way is to have power to the first 3 way switch, then 3 wire cable from the first to the second switch, then 2 wire cable from the second switch to the lights.
This way also gives you the neutral in each switch box, a requirement of the 2011 National Electric Code. This also allows you to put dimmer switches, or other devices that need power, in the switch boxes at a later date..
The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.
Ok thanks, I was thinking of going that way since my wife wanted a plug by the "stair 3-way" and therefore needing a neutral. So basically there is no "limit" on how many lights can be controlled by a 3 way aside from feed limit (12 devices)
