Light Switch Hot Wire Top Or Bottom

Connect the last switch in the usual manner looping the wire around the screw in a clockwise direction.
Light switch hot wire top or bottom. The hot wire in a 120 volt residential ac circuit usually is coated with black insulation while the return or neutral wire is white. In the attic had all. In this picture you can see the strip gauge on the back of the switch. I m trying to install a motion sensor light switch that is a replacement to a standard one.
Connect the source wire to the bottom terminal of the switch and the other black wire to the top terminal. Instead of running a separate pigtail from the hot wire to each switch just leave the hot wire extra long. The other two however on the old switch i understand one is supposed to be black and one is supposed to be white. This gauge is when you want to use the quick connect method when wiring a light switch.
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. The other terminal is for a second hot wire called a switch leg that runs only between the switch and the light fixture. 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. One screw terminal is for the hot wire that feeds the switch from the power source.
The hot black wire from the power source travels through the switch and from there to the light. Simply strip the wire to the length specified and push the wire into the hole. There are three wires. A single pole single throw switch such as a light.
That leaves me with one black hot wire that goes from the junction box to the light fixture. Skip to the bottom if you want to see the essential question. Flipping the switch interrupts the flow of electricity to the light turning it off and on. Wrap wire on terminals in a clockwise direction.
I know which one is the ground. The switch leg brings power to the fixture when the switch is turned on. It could be there is or once was a three way switch in play. Ok this is a very simple question.
When you see a red wire in a light switch box it can mean two things. If the line carrying power comes into the light box first the circuit must still be wired so the switch interrupts the black line. To connect the switches simply score the wire with your wire stripper and push the insulation to expose about 3 4 in.
