Kind of long story.. I had a run of half hot outlets in a bedroom. I added a wall sconce and ran wire pigtailed off of one of the outlets half way through the run to have a switched reading light. We want that light to be dimmable, so I also replaced the old switch with a dimmer switch.
Then I learned dimmable outlets are a bad idea..
So, I replaced the outlets in the run with new outlets, leaving the tab in place. The run uses 3 conductor wire (w/r/b) and I've just twisted together the reds in each box and have black to black + the outlet, and white to white + the outlet.
My question is, what do I do with the switch (red) wire in the last box? Do I just cap it off? Is it ok to have a sometimes hot wire capped off in the box? That's what I've done, and everything seems to work, just makes me nervous having that one wire not connected to anything and sometimes hot, seems wrong.
Thanks in advance!
