I have a 15 AMP circuit powering a 3-way switch [A] - 14/3 - 3-way switch [B] to 14/2 to 6 recessed lights in kitchen. The power comes into the Switch[A]. I want to add a single pole switch in location switch[B] to run a hanging light pendant. Can I get power from the 3-way Switch [B] and hookup the new pendant light or do I need to run new power for the pendant light? If I need to run new power can I run 14/2 wire to switch box [B] from a 12/2 box in basement that is on a 15AMP circuit?
The 12/2 wire I ran in the basement for lights and 2 outlets when I first moved into the house but they are on a 15 amp circuit. If I run power from one on the basement outlets 12/2 to the switch[B] 12/2 and then run from single pole switch 14/2 to pendant light .. would be OK?
