Reply to comment by builder-f4n4tic in Can I install this single pole switch in place of the dimmer switch that was here? by Affectionate_Cronut

The dimmer switch had 2 black single wire leads coming from it, one was wired to the single black wire, and the other was wired to the pair of black wires twisted together. The house is a modular built and wired in Canada, if that makes a difference.

The single black was most likely the light and the twisted pair was likely the branch line. The switch sits in the middle to be a switch/interrupt of the power.

Sigh. In Europe, the colour coding would help - switched wires have a different colour.

It seems like the 2 blacks are basically the live wire passing thru that .. wall box?
