what happens if you connect white wire to black wire？
If you see both sides connected together, it means it's a switch loop. The white wire that's connected to the black wire carries power to the switch. And the black wire that's in the same cable carries back that switched power to the outlet.2022年1月9日
Then,What happens if white and black wires are reversed?
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.
Furthermore,What happens if black and white wire 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.
Subsequently, question is,What happens if you reverse hot and neutral wires?
One common issue with electrical outlets is reverse polarity, also known as "hot-neutral reversed." In this condition, the outlet has been wired incorrectly, altering the flow of electricity. While the outlet will still be able to provide power to your electrical items, it is also present a greater shock hazard.
One may also ask,What happens if you get live and neutral the wrong way round?
Because when it's the wrong way around, the device is energized (the internal wiring is at a voltage potential higher than 0). So if there's a fault somewhere, you could potentially become a path to ground. Also in some older appliances, the grounded (neutral) conductor was bonded to the chassis of the device.
If you damage the wires during installation, you could break the switch, or the wires could come loose. Loose wires present a danger when changing the light switch. Thirdly, you could create a short circuit in the switch. A short circuit can cause the breaker or fuse to pop.
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.
The fixture still works if you reverse the wires, but the socket sleeve will be hot, and anyone who touches it while changing a bulb can get a shock. When wired correctly, the socket sleeve is neutral and only the small metal tab at the base of the socket is hot.
White (neutral) goes on the side allocated for the larger prong. Black (Hot) goes on the smaller prong side or white to silver screws, black to gold screws. Ground (bare wire) to green. 3) Strip wires, about an inch.
Basic Wire Color-Coding A white neutral wire usually connects to a silver-colored terminal or white wire lead. A green or bare ground wire almost always makes a ground connection—to a ground screw on a device, electrical box, or appliance case or to a green wire lead.
White Wires with Red/Black Tape – Hot Typically, white wires are neutral wires. However, in some cases, the white wire is modified by adding red or black tape to it. This modification signifies that the cables are being used as a live wire, and they should be handled with caution.
To check if you have a neutral wire, you can pop open a switch box in your home, if you know how to do so safely (you can also have an electrician come do it). If you see a white wire coming out of the gang box, you likely have a neutral wire.
Nothing. Two hots of same circuit - nothing should happen.
