I am going to install 4 LED downlights on a 3-way switch. My plan is to do panel-switch-switch-lights... similar to this image



enter image description here



I will be using THHN inside conduit from panel to first switch, and from first switch to second switch. My question is do I need to splice the neutral in the first switch box, or can I just make it a continuous run from panel - through first switch box - spliced to NM-B in second switch box?



Alternatively, is it good practice to splice here (provides future capability) or bad practice (unnecessary point of failure)?

  • Do be sure to leave enough wire in each box that if someone changed to a switch that needed a neutral (i.e. a smartswitch, typically) in the future, they could cut the neutral and splice in a pigtail for that.

To me the choices are equally acceptable. I don't see either as a good or bad practice. As long as a good splice is made it will last indefinitely. And sometimes I like less clutter in the box.
