Last week I helped my Mom unpack in her new house. I also had the brilliant idea that she needed dimmer switches. As my family knows, I have a hatred of overhead lights and I'm always trying to find a way to eliminate or minimize them:
ME: "Ow, Mom, it's so darn BRIGHT in here at night."
MOM: "Well I suppose there are a lot of light bulbs..." (glances, uncertain, at ceiling)
ME: "You need a dimmer switch. No, two. No, THREE! Kitchen, bar, and dining room."
MOM: "Sure, honey, that sounds great". (with a touching overconfidence in her eldest)
We went off to the hardware store. Purchased three dimmer switches. Came home. Took the switchplate off the wall.
And let the fun begin. The next morning, I finished the job... if by "finish" we say she had working lights and the dining room switch no longer turned off the guest bathroom and guest bedroom lights. And she had one operating dimmer, plus an upside-down switch for her bar lights. Call it my electrician signature.
The hardware store guy, who I saw three more times that day, started making jokes about putting me on the payroll, seeing as how I was at the store all the time. I suggested getting an employee discount but his hearing seemed to conveniently cut out on him at that point.
I'll sum it up with you for some actually valuable suggestions, should you decide to embark on the "easy" task of putting in a dimmer switch:
1. BEFORE you go to the hardware store, take the switch plate off and pull out the existing switch to look at. We were surprised to learn that she had three-way wiring in all her switches, even though she only has one switch per set of lights.
Too bad we figured that out after we hacked open the dimmer switch packages... all of them for ONE-WAY wiring.
2. Take a picture of the existing wiring before you take it off the switch. As much as you hate to admit it, you might end up having to re-wire into that existing switch.
3. If you have the switches with the wires stuck INTO the switch, instead of just screwed to the side of it, don't just yank them out. You may not think you are strong enough to break electrical wire... but you are. Oh, you are. Get a teeny flathead screwdriver and stick it in the little opening below where the wire goes into the switch. Wiggle the screwdriver. Swear loudly. And then POP, out comes the wire without breaking.
Good luck, fellow home electricians...
