It doesn't matter which of your two hot wires are where, the switch will only has 1 on and 1 off position. Turning it upside down will make it work the way you want it to.

Just so, how do you flip a light switch?

the way you presently described your switches, both up (on) and your light off is common. if you flip one switch up to turn the light off and then go to the other switch and flip up to turn the light back on, then both switches will look the way you want. the next time you use one it will be backwards again.

Also Know, what happens if you reverse wires on light switch? This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it's usually an easy repair. One of these wires is connected to the earth, or 'grounded', so this wire is called the grounded conductor.

One may also ask, will a light switch work if I wire it incorrectly?

If either wire at the light fixture is still hot then the switch is wired incorrectly. If one of the wires is still hot at the light fixture with the switch in the off position, then you most likely have the light switch on the neutral wire. Separate the bare ends of the wires so you can safely turn the power back on.

Why is my light switch upside down?

If it's a single pole light switch, you should just be able to take it out, turn it 180 degrees, and rewire it. It doesn't matter which of your two hot wires are where, the switch will only has 1 on and 1 off position. Turning it upside down will make it work the way you want it to. It's more about the dimmer switch.

Which way is off on a light switch?

Flip a light switch somewhere near you. Very often these light switches are set up so that down on one light means "on" while it means "off" on another light in the same house; this is especially common when two switches affect the same light, so you can't depend on the physical direction.

Does it matter which wire goes where on a light switch?

If your switch has a “LINE” marking, the always hot wire goes to this. The other connection will be “LOAD” where the load (ie light fixture) is wired. The load wire may have red electrical tape on it to differentiate.

Do you need an electrician to change a light switch?

Replacing light fixtures
If the amperage isn't high enough to cover the wattage of your new light, you will need an additional wire run from your circuit breaker. It's best to hire a licensed and qualified electrician for such a task.

Does it matter which wire goes where on a light fixture?

Light fixtures manufactured in the United States must follow the color-coding rules established by the NEC. However, the NEC has only one requirement, and that is that the neutral wire must be white or gray. Most North American manufacturers make the hot wire black and the ground wire green, but they don't have to.

What happens if you switch hot and neutral wires?

The neutral wire is connected to ground at the breaker box, which is connected to physical ground nearby. If you switch the hot line and leave the neutral, then the whole device will be at neutral potential. However, stuff happens, and by switching neutral instead of hot you have removed one layer of safety.

What happens if you reverse hot and neutral?

This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it's usually an easy repair. This wire is commonly referred to as the neutral wire, and it should always be white.

Why is there 2 black wires on light switch?

The bare or green-wrapped ground wires serve as a backup to divert the power safely away in case of an electrical fault. In most cases, two black wires will be attached to the switch's two terminal screws.

How do you wire a light switch without neutral?

Option 1 - Run a Neutral Wire
If you want to use smart switches and don't have a neutral wire in your switch box, you can hire an electrician to run a neutral wire between the light fixture and the switch. You can also have an electrician rewire the switch and light fixture, which is potentially more expensive.

What happens if you switch hot and load wires?

Here's what happens when somebody wires a GFCI receptacle with the load and line wires reversed: The GFCI will work, in the sense that you can plug in a hair dryer and the hair dryer will blow hot air. If the load and line wiring gets messed up, a ground fault (radio in the tub) won't trip the GFCI.

How can you tell which wire is positive and negative when 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.

Will reverse polarity trip a breaker?

Reverse polarity will not trip a breaker. Only a dead short will. Pull the receptacle out and give us clear pictures of all the wires and connections. It sounds as if you have connected the grounded neutral conductor on that circuit to the hot wire, probably at the receptacle terminals.

Can Reverse polarity cause a fire?

Watch out: Reversed polarity on an electrical outlet is dangerous. If you accidentally reverse these wires the device you plug in to the receptacle may "work" but it is unsafe and risks a short circuit, shock, or fire.

Can a start capacitor be wired backwards?

In an AC circuit it does not matter if a capacitor (intended for that circuit) is wired backwards. In a DC circuit, some capacitors can be wired backwards, others cannot.

Can I wire lights and outlets on the same circuit?

An option for you if you don't want two switches is just to use a blank face plate (check this question). Basic answer to your question of can a mixture of lights and receptacles be installed on a single circuit is yes. The neutral will be white but some switches are wired up with a white wire that is not a neutral.

What color wire goes to the black screw on a 3 way switch?

The black wire from the circuit breaker panel gets attached to the black screw on the 3-way switch. The black and red wires from the white cable running between the switches get connected to either of the two brass screws on the switch. On the other end, the two white wires are wire nutted together.

How do electrical fires start?

Most electrical fires are caused by faulty electrical outlets and old, outdated appliances. Never use an appliance with a worn or frayed cord which can send heat onto combustible surfaces like floors, curtains, and rugs that can start a fire. Running cords under rugs is another cause of electrical fires.

What happens if you wire a light switch wrong?

If either wire at the light fixture is still hot then the switch is wired incorrectly. If one of the wires is still hot at the light fixture with the switch in the off position, then you most likely have the light switch on the neutral wire. Separate the bare ends of the wires so you can safely turn the power back on.
