Extension cords which is hot wire

This means the plug is not being overloaded. There is a defect in the hot side. The original cause might have been as simple as the connection was loose or too many strands of wire were cut when the wire was stripped. You may be able to rehabilitate the plug by loosening all the connections and pulling off the wire, then cleaning off the hot connection with a small file or emery cloth. Then cut off the end of the wire, strip the wires carefully, then remake the connection.

How long are these cords? What are they plugged into? What rating is the extension cord? The inrush can damage things overtime.

Also, any, and I do mean any, possible kinks in the cord. I had one that kept blowing a fuse simply because the foot of some equipment had gotten on it for a short time and it was just enough to break the insulation on just the wire inside, not the rubber jacket outside. Left alone it might have been ok, but it had led to tripped breakers and a short in the plug like yours. Possibly dangerous situation. Sign up to join this community.

It's always being replaced. Is this normal? Read these 4 easy steps to help you rewire and replace your extension cord. The prongs on extension-cord plugs are easily bent—and easily straightened with pliers.

But after a few such re-straightenings, the metal can fatigue and snap off. For about five bucks, you can attach a replacement plug. Looking for help with home repairs?

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.

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. Place the prong of the multimeter's black wire on the bare metal on the end of a white wire , then read the meter. If you get a reading, the black wire is hot ; if you don't, the black wire isn't hot.

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. 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.

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. You can clearly see that red is connected to the new brown live , black is connected to the new blue neutral and the green and yellow earth stays the same.

The black hot wire goes to the brass screw or into the hole in the back of the device on the same side as the brass screw. This wire is sometimes red. The green or bare copper ground wire, if the device has one, attaches to the green screw terminal on the switch or to the electrical box.

The simple explanation is that every color used for electrical wiring has a specific meaning , with different colors indicating different circuit types and purposes. NEC imposes the following electrical wiring color standards: Ground wires : green, green with a yellow stripe, or bare copper.
