I have 2 simple X10 wall switches I want to install in my apartment. My problem is that both wires going to the existing wall switch are black. 1 goes to the top and one to the bottom of the switch.
My X10 switch is a WS467 and has a black and a blue wire. The instructions state: Black (to live or lamp) Blue (to lamp or live)
Does it matter which of the 2 black wires the blue wire is attached to??? Don't know if it matters but there is also a coupler (plug) with white wires terminating inside it, but none go to wall switch.
Thanks for answering what is probably an ignorant question
JC, the "coupler" is a wirenut, which in your case, is joining the neutrals. The black and blue don't matter with a single-pole switch; either one to either black house wire.
