a white and black electric wire twisted together in box The white wire twisted to the black is carrying the hot to the switch. The black wire by itself is the switched power. It is a switch loop. Typically used on aluminum parts over 0.40” thick, open corner joints can be welded using several methods: fillet/seam, fuse, tack, or stitch welding. Our expert welders can determine the right approach based on the characteristics of the material and how much weld is needed to fill the open corner.

Utilize filler metals (wires) that are slimmer as compared to reedy sheet metal. Numerous welders utilize 0.023-inch diameter wires and 0.024 inches for slimmer sheet metals. 18-gauge metals such as stainless steel have wire diameters of 0.030 and 0.034 inches. Align your torch angle to stop burnout in the SCT model.
The cable with the white wire that's connected to the two black wires is a switch loop: Normally wires with white insulation are used only for . A black and white wire come in to feed the box, a black and white wire leave the box to feed something else. They are connected together with .

The white wire twisted to the black is carrying the hot to the switch. The black wire by itself is the switched power. It is a switch loop. 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 .
Customer: Why are there three sets of black and white wires coming to a switch box that only has 2 switches in it. The two switches I have just removed were connected to one another (There . The black wire from the light is twisted to the white wires, then the white wire is twisted to the separate wire that runs to the switch on the wall (twisted to white), then the black .

The cable with the white wire that's connected to the two black wires is a switch loop: Normally wires with white insulation are used only for neutrals, but code makes an exception to allow for use of the white wire in a cable used as a switch loop as a hot rather than a neutral.
A black and white wire come in to feed the box, a black and white wire leave the box to feed something else. They are connected together with that short piece to feed the outlet. It's easier than messing with 4 wires in and out of the outlet and replacing outlets is easier. Long answer with explanation: When the power feed comes to the light fixture, the cable going from there to the switch is called a switch loop. You have six conductors, two from the power feed, two from the fixture, and two from the switch cable. 1. Neutrals must be white. The white wire twisted to the black is carrying the hot to the switch. The black wire by itself is the switched power. It is a switch loop.
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 .Customer: Why are there three sets of black and white wires coming to a switch box that only has 2 switches in it. The two switches I have just removed were connected to one another (There was a wire going from one screw on one switch to a screw on the other switch).
The black wire from the light is twisted to the white wires, then the white wire is twisted to the separate wire that runs to the switch on the wall (twisted to white), then the black from the light switch is twised to the white ones in the box, and everything is grounded.On the switch should be a white 120v power wire (black and white twisted together in the ceiling box), and a black return wire (the single black wire in the ceiling box). It looks like an inline switch to me, which is usually indicated by a mark on the wire. Are there any black markings (Eg sharpie or electrical tape) on the white wire?
