At present, the first thing to do in home decoration is to install the plugs and wires of the wires. Because there are too many electrical appliances in the home. If we don't arrange the wires and choose the wires well, there will be some hidden dangers to the safety of life. When we decorate, how much do we know about the connection and wiring of the wires? We live in our own homes, so it's good for us to know something about them, The manufacturer of fireproof cable company said the following precautions.

1. In the process of connection, the wiring shall be carried out according to the above marks. Generally, there are power supply and load marks on circuit devices. Do not connect them upside down.

2. The control switch or protection line shall not pass through the current transformer. When the three-phase five wire system or single-phase three wire system is adopted, the protection line must be connected to the protection trunk line at the incoming end of the leakage circuit breaker. In case of single-phase lighting circuit, three-phase four wire distribution line and other lines or equipment using working zero line, the zero line must pass through the current transformer.

3. In the transformer neutral point direct grounding system, once the leakage circuit breaker is installed, the working zero line can only be used as the working zero line after passing through the current transformer. It cannot be repeatedly grounded or connected with the working zero line of other lines. The electrical equipment can only be connected to the load side of the leakage circuit breaker. It is not allowed to connect one end to the load side and the other end to the power side.
