In standard 120-volt wiring, the hot wire is black, but it can also be red. In most cases, you see a red wire in an outlet box only in special circumstances. One is that the outlet is a 240-volt one, which requires an extra hot wire. Another is that the box is on a circuit three-way switch loop.


Distinguishing between line and load isn't always necessary. For example, a conventional wall switch -- which is a single-pole, single-throw switch -- works equally well whether you attach the live circuit wire -- line-- to the top brass terminal or the bottom because the switch has only two positions -- open or closed.The terminal connections are directional on a double-throw switch, on the ....


What Color Is the Load Wire? In a circuit, the main load wire — the live power wire between the switch and power source — is typically black, and the secondary load wire is usually red. Wire colors can vary between circuits, so it is best to remove or turn off power sources before touching them.


The exact purpose of a red wire for a light fixture can vary. Except in rare cases, it is a hot wire or a switched hot wire. Check the wire with a non-contact voltage tester with the power and ...


red and black may be used interchangeably to represent the "hot" wire. white is always neutral.(return wire) and green/bare copper is always ground. you got it exactly right! if there is a ground wire for the fan, connect that ground wire to the chassis/electrical box supply's ground wire.


When you see a red wire in a light switch box, it can mean two things. It could be there is (or once was) a three-way switch in play. Or it could be the red wire is the wire going to the fixture, and the black wires are the live wires. We’ll cover the easier scenario first.


The Load wire is always hot (black or red wire) and the Line wire is the one that returns to your fusebox (usually white). Answer above is absolutely wrong written by someone who does not know ...


If you don’t have a load then the dumb switches wouldn’t control anything. The load is the device being controlled, like a light. If there was no load wire going to a device then the switch wouldn’t do anything. EggYolk (Matthew) January 18, 2018, 8:36pm #11. The switch in my bathrooms and hallway do not have a load wire (2nd black wire ...


If you're wiring an outlet for a 240-volt appliance, such as a stove or air conditioner, you'll also need three-conductor cable with a wire gauge of at least 10 AWG. In this case, both the red and black wires are hot and connect directly to the circuit breaker in the main panel. Connect the black wire to either of the brass screws on the outlet ...


5. Look on the back of your indoor timer light switch to identify the wires. Each timer manufacturer uses different colored wires to indicate the load, such as red or blue.
