What it concludes

In most jurisdictions, it is permissible to do your own electrical work in your own home.
Score the interface between the wall and faceplate with a razor blade to prevent tearing drywall paper and paint.
Always test on a known hot source first to confirm the voltage tester is working.
Do not use speed wiring when installing new light switches; use side wiring for better reliability.
Tighten down screw terminals on 3-way switches to prevent loose wires and potential shorts.
Match your replacement switch and faceplate brand and color to the room's existing hardware.
