George Baker is a used car salesman who live in Chino Hills, California and he live in a studio cottage overlooking a golf course overrun by carts and flying golf balls. George is a tinkerer and he touches everything he believe that he can repair. He did mention that the dimmer switch had never worked and the ceiling light had never worked since he purchase his home.

This post shows the twelve steps on how to replace a standard dimmer switch in a dining room.

Step 1: Fig.1 shows the removed the dimmer switch plate and wires.
Step 2: Fig.2 shows that the electrical circuit for the dining room outlets is turned off.  The most important step in this job is safety, and this job requires that the power is turned off.

Step 8: Fig.8 shows the switch remove each wire nut from the old switch and replace with the new switch. After hooking the hot black wires from the box to the switch, twist and attach a wire nut to the ground wires. Black electrical tape is attached to each wire nut making sure they do not come apart.
