Episode 3 – Wiring For And Installing A Switch

This episode covers the basics of installing an electrical switch.  I cover mounting boxes, drilling holes, running 12/2 romex from a power source to a new switch box.  From that switch box I install another piece of 12/2 romex to a light above.  After wiring and rough-in I install a decor single-pole 15a switch and a keyless fixture with a lightbulb.

I talk briefly about how to rip out wires and twist joints, as well as how to test with a multimeter using continuity to see whether or not a bulb is bad.  This is the very beginning of a series from basic to advanced that will show apprentice electricians several different ways to install electrical materials and devices.

    1. I’ve done that as well, but I’ve found if I let a helper drill out they often times just keep following chalk lines rather than following specific marks I make. Still a good idea, but it takes longer to set up each wall, or it requires 2 people to do so its just slower in my experience.
