Recently, I have installed a double switch box where a single light switch was previously installed.

One switch is for a dedicated line from my panel for deck lights recently installed, and the other switch has two power sources coming in, but I am having problems wiring them. On the single previously installed switch, was the side deck light fixture, my kitchen lights, and also the basement lights in the workshop.

I did not do the disconnection originally, and now I am having problems wiring them up, as whatever I do, it seems to trip the breakers.

I am totally frustrated and cannot seem to get it right, please help!

How are the two power sources you mention involved? Only one source is needed, while the other is capped off.

There are two power sources coming in to the single switch. Do I connect one to the light switch and cap the other one ?

Each feed should be a pair of wires, black hot and white neutral. Use one pair, cap the other pair, cap each wire indivdually with wirenuts.

Do you mean cap each pair? Or each wire?

Here you go:


cap each wire indivdually with wirenuts.

What is the proper mounting height for a switch box and a plug box in a new construction?

Any height you like is fine, outlets are typically 16-18" center , and switches are 45-48", all above finished floor to center.
