What about the wire connector? What should I pay attention to when connecting wires?

First of all, what should I do with the wire connector?

First, after the wires are combined, the two ends of the wires are treated with hot tin, which can play an anti-oxidation role and avoid the occurrence of fever and burns due to poor contact. Of course, you don't have to do this, but it will be better. If you don't do tin-ironing, you can use a professional drill to firmly wind the wire for 6 to 7 times when you merge the wire, which will also play a very good role. If the master is skilled, he can also wrap it by hand.

The second method is to treat broken wires with wire pressing pliers. The method is to wrap the two wires, then put a copper tube on the joint, then press it with wire pressing pliers, and finally wrap it with insulating waterproof tape. The advantage of this is that the joint will be very firm and not easy to loosen.

The third way is to use professional terminals to connect wires. This method is more suitable for multi-stranded wires, and it will be more convenient to change wires later. The only drawback is that it will increase the cost of water and electricity, which is rare in the current decoration. But it is undeniable that this is a very standard wiring method.

Second, what should I pay attention to when connecting wires?

1, general circuit equipment has signs of power supply and load on it. In the actual wiring process, just follow the signs above, and remember not to connect the two sides backwards.

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

3. In the system where the neutral point of the transformer is directly grounded, if a leakage circuit breaker is installed, the working zero line can only be used as the working zero line after passing through the current transformer, and it cannot be grounded repeatedly, nor can it be connected with the working zero line of other lines. Electrical equipment can only be connected to the load side of the leakage circuit breaker, and it is not allowed to connect one end to the load side and the other end to the power side. What about the wire connector? The wire connector must be treated according to the actual situation to ensure the safe transition of the wire connector. What to pay attention to when wiring. Wire connection must be handled by professionals to avoid all kinds of dangers caused by wire connection problems.
