Light Switch Hot Wire Top Or Bottom

If the line carrying power comes into the light box first the circuit must still be wired so the switch interrupts the black line.

Light switch hot wire top or bottom.

I m trying to install a motion sensor light switch that is a replacement to a standard one. Simply strip the wire to the length specified and push the wire into the hole. It could be there is or once was a three way switch in play. The other two however on the old switch i understand one is supposed to be black and one is supposed to be white.

In the attic had all. Skip to the bottom if you want to see the essential question. Instead of running a separate pigtail from the hot wire to each switch just leave the hot wire extra long. Then i added the second set of wires and tried to run a pigtail from the hot wires in the box black and red pigtailed together to the bottom screw and the white wire on the top screw.

This gauge is when you want to use the quick connect method when wiring a light switch. In this picture you can see the strip gauge on the back of the switch. A single pole single throw switch such as a light. Wrap wire on terminals in a clockwise direction.

One screw terminal is for the hot wire that feeds the switch from the power source. Flipping the switch interrupts the flow of electricity to the light turning it off and on. To connect the switches simply score the wire with your wire stripper and push the insulation to expose about 3 4 in. The hot black wire from the power source travels through the switch and from there to the light.

They have two screw terminals plus a ground screw. But remember for the light switch we need one black wire coming from the power source to the light switch and one black wire going from the light switch to the light fixture. Connect the last switch in the usual manner looping the wire around the screw in a clockwise direction. There are three wires.

When you see a red wire in a light switch box it can mean two things. Ok this is a very simple question. The switch should be up when it is turned on also you will read on and off as opposed to no and ffo on the switch. I know which one is the ground.

The other terminal is for a second hot wire called a switch leg that runs only between the switch and the light fixture. Idealy connect white to top terminal black to bottom terminal bare ground to green screw on switch reinstall switch restore power and test by turning switch on. That leaves me with one black hot wire that goes from the junction box to the light fixture.
