Four 3-way switches, two lights, two ganged device boxes.
What's the best practice method to wire a lighting circuit where 3-way switching is required for both feeds on a two circuit track light installation?
The track has a shared neutral and two hot wires that are intended to be switched independently.
The track will be switched from two locations. Each location will be fitted with two 3-way switches in a ganged box, using the power-at-one-end 3-way switch method.
Running two separate 14/3 cables, one for each 3-way switch loop would mean having a parallel neutral wire.
Running one 14/3 for one switch set and a 14/2 for the other (with the sole neutral in the 14/3) would mean violating conductor grouping rules.
Is there any way to what I want without using 14/5 cable or conduit?
