Why would there be two hot wires?
The reason for multiple hot/neutral wires for one outlet is that the outlets are daisy-chained together. This means hot/neutral is only coming from one of the wires and it is being sent to the other wire.

Which wire is hot on switch?
black wire
The black wire is the “hot” wire, it carries the electricity from the breaker panel into the switch or light source. The white wire is the “neutral” wire, it takes any unused electricity and current and sends it back to the breaker panel.
Can you connect two hot wires together?
Nothing. Two hots of same circuit – nothing should happen.

How do you identify a switch leg?
Quote from the video:
Quote from Youtube video: As long as you identify it with some black tape or a felt pen just to color that in and let people know that that's meant to be tied into the hot wires. So on that white conductor.
Why do I have 2 live wires on my light switch?
If there are two wires in the box then it can only be the Line (Live) voltage ‘IN’ which is then switched by the switch to the Switched Live (S/L) which passes the supply to the bulb with the bulb getting its ‘Neutral’ from the Junction Box and or the light rose.

What happens when two hot wires touch?
A short circuit happens when a “hot” wire (black) touches another hot wire or touches a “neutral” wire (white) in one of your outlets. When these two wires touch, a large amount of current flows, creating more heat than the circuit can handle, so it shuts off.

How can you tell which wire is hot without a tester?
Quote from the video:
Quote from Youtube video: We're gonna put our black probe on that middle wire and then we're gonna touch the red probe. To one of the wires. Now the wire if it gives voltage that's the hot wire.
Does it matter which wire goes on a switch?
In the case of a single-pole switch, these wires are interchangeable—it doesn’t make any difference which wire is attached to which screw terminal. Inside the switch is a metal pathway that closes when the switch is in the ON position and opens to interrupt the flow of power when the switch is turned OFF.

Why are there 2 black wires on light switch?
Black means hot, white signifies neutral, and green indicates ground. However, if you need to rewire a light switch or a plug socket, you may occasionally come across two black wires. It’s essential that you determine which black wire is hot before proceeding.
What is a 2 wire switch leg?
The switch-leg is still made up of two wires, but the hot wire connects directly to the switch and the two wires connect directly to the outlet. The second wire completes the circuit by connecting to the house neutral wire in the switch wiring box, instead of in the outlet wiring box.
Can the white wire be used as a switch leg?
No more, no less, it simply breaks or completes the circuit, no matter the color of wires connected. The reason why a white wire was allowed to be used for hot in a switch loop is that this allowed common non metallic cable with two insulated wires to be used.

Which wire is hot when both are same color?
In most modern fixtures the neutral wire will be white and the hot wire is red or black. In some types of fixtures, both wires will be the same color. In this case, the neutral wire is always identified by some means. In some cases, there will be small writing on the wiring case.
What is a secondary hot wire?
Red wires are usually used as secondary hot wires. Red wires are also hot and should be clearly marked to avoid the dangers of electrocution. Red wires are commonly used when installing ceiling fans, where the light switch maybe.

Can 2 hot wires share a neutral?
What is a multiwire branch circuit? A multiwire branch circuit is a branch circuit with a shared neutral. This means there are two or more ungrounded (hot) phase or system conductors with a voltage between them and a shared neutral.
How do I wire a 2 wire switch?
Quote from the video:
Quote from Youtube video: And so you've got two wires that are underneath two sides of the clamp. And then there's a third wire. That's going into a push in terminal on the back of this single pole switch.
How do you wire up an old light switch?
Quote from the video:
Quote from Youtube video: You can just put the wire. Straight in to the terminal. And then screw this screw down. Or. You can go around the terminal. And then tighten the screw down.
Is the black wire the hot wire?
Hot wire is identified by its black casing. This is the main color of hot wire for most homes. However, other hot wires can red, blue, or yellow, although these colors can indicate a different function besides powering an outlet.
What happens if you don’t ground a light switch?
So there you have it, your home may opt for screws, cables, or grounded boxes, but your switches should all have a ground outlet to ensure your safety is secured. Without it, you put your body at risk of completing a circuit holding lethal electrical charges.

Can you wire a switch without a ground wire?
For a normal light switch, the ground is a safety feature, not necessary for operation. You can leave that screw unconnected if you don’t have a ground wire, or if you have the wire but no screw on the switch, you can ground the switch another way.

Can you use neutral wire as ground?
The “neutral” is more appropriately called the grounded conductor. It is a live circuit conductor. Yes, it is grounded, but you must not bond the neutral and the grounding conductors anywhere other than the main panel.
