Is the black line a live line or a zero line?

In our daily life, many things can be repaired by ourselves, such as broken light bulbs or other electrical appliances. When some parts need to be replaced in the middle, we can do it ourselves. But when we finish, we should be careful not to connect the wires wrong. If we connect the wires by mistake, we have to take them apart and reconnect them, which is a very troublesome thing. At present, many users can't tell the clear line from the live line. Is the black line a live line or a zero line? Today, Bian Xiao will tell you whether the black line is the live line or the zero line. I hope I can help you solve the problem. Interested friends come in to find out.

1. Is the black line the live line or the zero line?

1. First of all, the black line is the zero line. Besides the black line, the green and blue line is also the zero line.

2. Blue and green are zero lines except black, and the rest are live wires and ground wires;

3. If you want to know whether it is neutral or live, we can not only distinguish by color, but also pass the electric pen test.

Second, the wiring matters needing attention

1, although we know what is the zero line and what is the live line, we must not connect wires indiscriminately, so we must put safety first. If we don't know how to connect the wires safely, it will probably lead to electric shock and even fire.

2. When connecting electricity, we'd better bring insulating gloves, and touching wires can prevent electric shock;

3. When wiring, the live wire and the zero wire must not be connected at the same time, because these two wires are connected at the same time, which will produce a great voltage and easily make people get an electric shock.

The above is the relevant information and content provided by Bian Xiao about whether the black line is the zero line or the live line. I hope I can help you.
