Why would a light switch have two black wires?

Why does my light switch have two black wires and one white wire?

The new outlet must have the tab broken off ALSO to prevent problems. Most likely the second black wire simply carries the power from that outlet to the next outlet in the circuit.

How do you wire a light with two black wires?

Join one of the fixture wires to the hot (black) electric wire from the switch and the other wire to the neutral (white) wire. With a voltage meter, attach one probe on the fixture pocket sleeve and the other on the ground wire. Request a helper to turn on the power (take caution to avoid a shock).

What do I do if I have two black wires?

Connect the top screw to the wire that feeds to the light. Connect the bottom screw to the hot wire. When you turn the power back on, and if you want to swap the direction of the switch (as in press down to turn off, or turn on), turn off the power and switch the two black wires.

How do you wire light with two switches?

Connect the black wire coming from the lightbox with the black wire leading to the second switch by twisting their ends together and fastening with a third wire nut. Connect the 2 ground wires with a fourth wire nut. Take the white wire leading to the second box and mark its end black too.

How do I wire two lights to the same switch?

How to wire four lights on one switch?

You can do this light switch wiring in one of two ways. The most common is to daisy-chain the light fixtures by connecting them to each other and hooking the first one up to the switch. The other way to wire multiple lights to one switch is to connect all of them directly to the switch in a “home run” configuration.
