The correct connection between the live wire and the neutral wire is shown in the following figure: How to connect the live wire and the neutral wire? Wiring is an important job in home renovation.
If there is a problem with the wiring, it will seriously affect life and endanger personal safety. Sometimes the question arises as to what order the wires should be connected, whether they should be connected to the neutral or live wires, and then the topic will be discussed. How to connect the live wire and the neutral line?
The general process of electrician operation is: if a wire is broken, the fire wire will be broken first, and then the zero wire will be broken; Connect the neutral wire first, then the live wire. Actually, under working conditions, some arcs are generated when an appliance is connected to the neutral or live wire, but the arc will be smaller when the neutral wire is connected, and the arc will be larger when the live wire is connected because the voltage is larger.
Therefore, when wiring the general household 220V low-voltage circuit, it is necessary to ensure that the human body is absolutely not grounded, and it is correct to connect the zero wire first and then the live wire. How to connect the live wire and the neutral line? General home renovation or circuit repair may bring a small current, so how to work with electricity?
Note that the electrician's hands cannot touch the wires at the same time, because if two wires are in contact at the same time, the human body will become a conductor between the neutral wire and the live wire, which is prone to accidents. The two wires need to be connected before operation, which can reduce the risk of arcing. How to connect the live wire and the neutral line?
When connecting, you should also follow the "left, zero, right, fire."
of the norms. When installing the switch, cut off the power supply first and install it in the circuit. It is necessary to ensure that there is no point equipment in the circuit to prevent large arcs caused by excessive loads.

The connection method of the live wire neutral line is generally: left zero right fire, live wire l (red, yellow, blue), zero wire n (blue or black), ground wire e (yellow-green).
Under normal circumstances, the ground wire will not leak, and the common ones are: two-hole, three-hole socket. In general, in the two holes, the left hole is connected to the neutral line, and the right hole is connected to the live wire. In the three-hole socket, the upper hole is connected to the ground wire, the left hole is the neutral wire, and the right hole is the live wire.
Firewire: The power cord that carries electricity in a circuit.
Neutral line: Mainly used in the working circuit, the main line is drawn out after the neutral point of the transformer is grounded.
Extended Materials. How to distinguish between the zero and ground wires:
Line of Fire (L): Red, yellow, green must be used.
Neutral line (n): black and blue must be used.
Ground wire (PE): Yellow and green two-color wires are required.
If it is a 3-hole socket, it is generally left zero and right fire, and the middle ground.
The ground wire cannot be connected to the neutral line, if it is reversed or mixed, although the electrical appliance can work normally, it is more dangerous.
When the neutral line fails, all equipment housings will become energized (even if the normal consumer is no exception). If a leakage circuit breaker is installed, the hybrid is a leakage switch that trips.

Normally, it is first connected to the zero line and then to the live wire, and finally to the grounding wire, in the case of electricity, the basic is the first grounding wire, then the zero line, and finally the live wire, in the wiring must turn off all electrical appliances, when accessing the zero line, we must always pay attention to the location of the live wire, to do some protective measures, wear insulation products during operation, under normal circumstances, the household socket is the left zero right fire, the general red line is the live wire, and the blue is the zero line. Hope to adopt.

The red line is connected to L, and the red one outside Ning is connected to N. The exchange of the zero wire of the socket is not a big problem. The yellow and green wire is the ground wire, and the middle must not be connected wrongly, because it is dangerous to connect the wrong wire.
-
The red line should be the line of fire, then take L
If red and green are switches, then the green wire is connected to L1
Yellow-green is the ground wire.
There is also a red line that I don't know what it does, it seems to be a single wire, there is no zero line, but I vaguely see a hole that is not wired (right).

If it is two wires with afterburns, and it is a one-zero fire, it can only be connected to a switch control socket, as shown in the figure below
If the two wires were originally used to switch the control lamp, changed to a switch with a socket, then if you want to switch to continue to control the lamp, the socket often has electricity, there is still one less zero wire, you must pull another zero wire nearby, in order to use the socket, otherwise the socket is unusable.
Therefore, it is recommended that the landlord describe the problem in detail and completely, so that everyone Duan Xiao can better help you solve the problem.

How to connect the live wire, neutral wire, and ground wire.
In a home circuit, there are usually three types of wires: live wire, neutral wire, and ground wire. The correct connection of these wires is very important to ensure the safe operation of the circuit and avoid possible electric shock and fire hazards.
The correct wiring sequence is: the power cable (live wire and neutral wire) is connected first, and then the ground wire. In simple terms, the following steps can be followed:
1. First, separate the live and neutral wires in the power cord (usually the power plug). 2. Connect the live wire to the wiring screw post on the heating equipment (such as an oven, electric stove, induction cooker) or the electrical hall (such as a TV, computer, refrigerator), which is the main power line of the circuit. 3. Connect the neutral wire to another wiring screw post on the heating appliance or appliance with it, usually marked "n" or "neutral".
4. Finally, connect the ground wire to the wiring screw post on the heating appliance or electrical appliance, usually marked "GND" or "GROUND". Please note that before connecting the wires, make sure that the circuit power is turned off and proceed with caution. Also, if you're not sure how to properly connect the wires, consider asking an electrician or other relevant professional for help.

The ignition wire marked L, the control wire marked L1 (light wire), and the two L's are connected together, (jumper).

Summary. N is the neutral wire, E is the ground wire, and L is the live wire, in the socket wiring, only need to connect the corresponding wire and the terminal hole.
How to wire the ground wire and the neutral line of the live wire?
Left zero right fire on grounding. There are three wiring positions in the three-core socket and plug, the top position of the triangle is the grounding wire, and the two positions side by side below should be connected to the live wire and the zero wire respectively according to the left zero and right fire. Note:
When wiring the plug, make sure that the plug is facing outward, otherwise you will connect the live wire and neutral wire. In this way, the live wire, the neutral wire, and the ground wire are connected.
Is that right? Left zero right fire on grounding. There are three wiring positions in the three-core socket and plug, the top position of the triangle is the grounding wire, and the two positions side by side below should be connected to the live wire and the zero wire respectively according to the left zero and right fire.
Excuse me, can you take a look?
N is the neutral wire, E is the ground wire, and L is the live wire, in the socket wiring, only need to connect the corresponding wire and the terminal hole.
When energized and measured with an electric pen, all the bright ones are the live wires, and the dark ones are the zero wires >>>More
Firewire wire colors are usually red, green, and yellow; The color of the neutral wire is mostly black and blue; The ground wire is generally a yellow and green wire. Some electricians do not follow the standard wiring when wiring, and you can also distinguish between the live wire and the neutral wire through tools such as electric pens and universal meters. >>>More
Measure with an electric pen the reason why both the live and neutral wires are bright: >>>More
It is necessary to divide the live line and the neutral line, and if the meter is connected and cannot be energized normally, it will not be used normally. >>>More
The two wires of fire cannot be separated, and then connected to the L-hole. >>>More
