Live wiring is what electricians often do. It's not illegal, but it's dangerous from a safety point of view. Should you connect the neutral line or the live line first? Only in the right order can we ensure safety!

Before the live wiring, check whether the line has load equipment (such as electrical appliances), if it has to be removed or stopped. Because the load will produce an arc, the load will produce a large amount of current. When operating, you must ensure that there is no electrical equipment in the loop.

Then check the wire insulation. Connect the cables to the neutral line first, then to the live line. Because the neutral line has no power, the operation is safe and pressure free, and it can be directly connected to the live line. On the contrary, when removing the wire, it must be operated in accordance with the specification of "first remove the live wire, then remove the zero wire".

If you do not operate according to regulations, first connect the live wire, the live wire may be transmitted through the load to the neutral wire, if the neutral wire contact with the body, there is a risk of electric shock." In a three-phase four-wire or three-phase five-wire system, if the neutral line is cut off first, the single-phase 220V power supply at the client end instantly changes to 380V power supply (the transformer end works normally). If an appliance is in use, this will cause damage to the appliance. This is why electricians must be careful when wiring and removing wires.

The wiring sequence must be correct. Cut the live wire first and then the neutral wire. Connect the neutral wire first and then the live wire. This must be borne in mind, especially for electricians who work on outside lines, if they make mistakes, the consequences will be borne by themselves and their employers!

Of course, when doing your job, you must ensure proper protection! Maintain their own equipment specifications, wearing insulated clothing, leather shoes, gloves, feet on 30 cm high dry wood, arms and bodies can not touch the wall or the ground, in the entire operation process, never use the hand directly contact the conductor, in order to ensure personal safety.

It is recommended that all electricians should be responsible for themselves and their families and operate in strict accordance with the specifications. Unless in an emergency, try to power off before operating!
