## How do you wire a light with two white and two black wires?

Take your always hot black and put it on your light switch, than take the other black in that box and put it on the light switch. Take your white that is in the same cable as your always hot black and wire nut it with your other white. Now go up to your light box.

## Why does my light fixture have two white and two black wires?

So, why are there two black and two white wires in your outlet box? There are two black and two white wires in an outlet box because the outlet is in the middle of a series circuit, accepting power from another source and sending it on. Two cables are hot wires, bringing the power in and carrying it onward to the next.

## How do you wire a light fixture with two white wires?

Quote from the video:
Quote from Youtube video: The two ground wires from the two cables are connected together but the ground wire from the light was not connected together with those two ground wires.

## How do you wire a light with two sets of wires?

Connect the lead wires from the fixture to the black hot wire in the electrical box by twisting a wire connector to the ends of the lead and hot wires. Repeat these connections with the two white neutral wires from the light fixture and the white neutral wire in the light fixture box.

## What if I have two black wires?

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.

## 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.

## Why are both black and white wires hot?

Here’s a rundown of electrical wires: 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.

## Why are there 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.

## What happens if you wire a ceiling light wrong?

But here’s the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work, but the polarity will be backward. When this happens, a lamp, for example, will have its bulb socket sleeve energized rather than the little tab inside the socket.

## Why would a white wire be connected to a black wire?

Because the neutral is re-tasked to be a hot, it must be marked with a few wraps of tape. White is used for always-hot because another rule requires this. That’s so when you’re at the other end, it’s easier to detect that the white Is hot, because it’s always hot.

## Which color wires go together?

See Table below. The protective ground is green or green with yellow stripe. The neutral is white, the hot (live or active) single phase wires are black , and red in the case of a second active.

US AC power circuit wiring color codes.

Function Line, 3-phase L3 blue yellow

## Can you have 2 black wires together?

This is the typical way to connect a switch. The 2 blacks connected are “power in, power out” to the next switch in the circuit. The pig-tail to the dimmer connected to the two blacks is also typical.

## How do you pigtail two black wires?

Quote from the video:
Quote from Youtube video: About 3/4 of an inch on both sides of both pieces of wire and this is going to be our pigtail.

## Which wire is positive when both are black?

If the multi-colored wire is black and red, the black wire is the negative wire, while the red one is positive. If both wires are black but one has a white stripe, the striped wire is negative, while the plain black wire is positive. Look in the owner manual to determine which wires are negative in a car.

## How do you tell which wire is hot and which is load?

Quote from the video:
Quote from Youtube video: And then remember gold goes to the hot. Side so the gold terminal. And that's on my line. Set and then silver goes to neutral or the white wire.

## What wires do I connect for a light fixture?

There should be at least two wires coming out of the fixture: a white (neutral) wire and a black (hot) wire. In this case, the two were conjoined and covered with protective plastic.

## Is the black wire with white lines positive?

The solid/dashed lines on wires like the ones pictured in your question are used to indicate polarity e.g. for the “wall wart” power supplies. Usually* the wire with the white stripe or the dashed lines carries the “positive” (+) end, while the other, unmarked wire carries the “negative” (-) end.

## How do you know which wire is positive and negative on a light fixture?

Touch one probe of a voltmeter to the top of the bulb socket sleeve (not the small metal tab inside the socket) and the other probe to the circuit ground wire and have a helper turn on the power at the service panel. If the meter indicates positive voltage, the wires are reversed.

## How do you tell a positive wire from a negative wire?

Quote from the video:
Quote from Youtube video: The rig the side with ribs on it is usually designating the neutral side of the wire. And. So when you hook up one end and you get to the other end you've hooked up your smooth side to the positive.
