That's how I like to do it too. ----- Original Message ----- From: RJ To: blindhandyman@yahoogroups.com Sent: Friday, February 05, 2010 5:04 PM Subject: Re: [BlindHandyMan] Wiring a switch.
The easiest way to explain wire a switch. Think of a solid black wire running from the power or line through a switch box to the light. and the same of the white. Now cut the black wire in half and put one half of the black wirer on the screw of a switch and the other half on the other screw. Leaving the white wire along. ----- Original Message ----- From: Ron Yearns To: blindhandyman@yahoogroups.com Sent: Friday, February 05, 2010 16:38 Subject: Re: [BlindHandyMan] Wiring a switch. Choice 1 and 2 are both ok. Mostly choice. Many electricians like to run the power in the ceiling and drop off for the switch. Others prefer to run power horizontally through the studs catching outlets and switches, then running a line up to the light. Yes the white wire in number one is spliced, wire nutted and put into thee switch box. I am not sure what you mean in number three choice. You can break into the power line anywhere. Providing a junction box is installed and left accessible, with a proper cover. All three are then code for safety. Of you are using a extra junction box and possible cable clamps and cover. Extra money. In rewiring old work it is what works. In new work a little planning can make for less hole drilling and wire saving. When using the white wire for a switch leg as when the power is ran to the light first the code way is to turn the white wire into a colored wire. This can be done by painting both ends of the wire or more commonly using black, blue or red tape around it for the length of the exposed white insulation.

Not that I have any immediate plans of rewiring, but this question popped in my head. I think I've seen a comment about this here before. If you are wiring a switch to a light fixture, do you: #1: Run a set of wires from the power source to the switch, and a set of wires from the switch to the light fixture. In this case, connecting both blacks to the switch terminals, and tieing the two whites together? Do you just stuff the white splice in the box with the switch? #2: Run a set of wires from the power source to the light fixture, and a set of wires from the switch to the light fixture. In this case, The white from the power would connect to the white on the light, and the two switch wires would be connected between the black power, and black light wires. It technically wouldn't matter which orientation you connected the switch wires, but is there a standard? I mean, black power, to black switch, then white switch to black fixture. #3: I assume this one is definitely wrong, but similar to #2. Run power directly to the light fixture, then just interrupt the black wire at some point with the switch wires. I believe choice #1 is the correct option, but is choice #2 against code? Choice #3 seems to be the most efficient use of wire, no parallel runs of wire, but would make it a pain in the ass to ever trace an issue since you wouldn't necessarily know where the switch spliced into the power line. Just a thought for the day. -- Blue skies. Dan Rossi Carnegie Mellon University.
