  1. I am trying to install a CAP MLC-4X and Im having difficulty figuring out what to do with the white/neutral wire coming from my wall... The instructions say that the 4 wire can be used with this model but nothing about what to do with the white wire. Do I just cap it off using only the red, black, and copper only or do I tie it to the ground/copper? I tried finding wiring answers online but am getting conflicting answers. Some say yes to tie it to the copper and others say that is an old way of doing it and no longer accepted. Can someone PLEASE credibly answer my problem and explain why???
