How to wiring the air switch, how to wire the air switch

First of all, if it is an indoor wiring, the letter marked N below is connected to the zero line, the zero line needs to be connected from here, marked with the letter A1 is the lighting line, marked with A2 is the sub-line of the socket, marked with A3 is the sub-line of the air conditioner. Then it is connected to the household line, marked with the letter N is connected to the zero line, and marked with the letter L is connected to the live line.

Air switchThe installation and wiring methods are as follows:

Before wiring, we first need to distinguish between different wires, because they represent different colors, and the correct way to do this is through an electric pen.

to distinguish between live, neutral, and ground wires. Because the live wire has a voltage value, but the neutral wire does not.

There is a one-way single wire in the air switch, which can only protect one live wire in the switch, so only one directional single wire and live wire need to be connected, in general, it is more suitable for lighting and low-power electrical appliances.

Used in a live wire and a neutral wire, this connection method is generally suitable for about 220 volts of electrical appliances, more than not applicable, you can connect a live wire and a wire left and right.

If you want to use 380 micro electrical switches, and to prevent its leakage, we can use three wires to connect, you can use three live wires to connect left and right, three live wires and one neutral wire.

The method is to find out the red live wire, the blue zero line and the ground wire of the suit, connect the three wires to the corresponding wire end, the lower end is the outgoing line, the upper end is the line, and the ground wire is not connected to the switch, in fact, the ground wire can not be connected, the red line is connected to the lower end, and the zero wire is connected to the upper end.

Attention needs to be paid to the wiring:

1. When wiring, first check whether the live wire has been powered off, if it is still in the energized state, it will affect the safety in this case.

2. On general equipment, there will be power supply and load on the above, so when installing, we must pay attention to whether the color of the wire corresponds well, the zero wire is cold, the live wire is warm, then the ground wire is the middle color, in the wiring process, according to the above signs, it must not be reversed.

3. If there is a problem with the junction box during the wiring process, the junction box should be replaced.

It is also secured with cement and sand.

4. If it is installed in the kitchen and bathroom, the water moisture in this area is relatively heavy, so it is best to choose a better waterproof, and some families will choose the socket with a safety stop for safety.

Nowadays, air switches have become an indispensable circuit accessory in almost every household, which can play a protective role in the event of circuit failure. If the circuit fails, the air switch will automatically power off to ensure the user's personal safety. So how to wire the air switch?

How to wire the air switch.

1. First of all, you need to understand what wire the different colors of wires represent, usually red represents the live wire, blue represents the neutral line, and yellow-green represents the ground wire. The air switch is front-mounted, with the upper line being the inlet and the lower part appearing, and usually the ground wire is not used to enter the switch.

2. If it is connected to the indoor wire, then the place marked with the letter N below is connected to the blue zero line, the part marked A1 below is connected to the live wire, and the part marked with A2 below is connected to the live wire sub-route of the socket wire. The part of A3 marked below is connected to the air conditioner fire wire branch. If it is connected to the incoming line, the place marked N above is connected to the neutral line, and the L is connected to the live wire.

What should be paid attention to when connecting the wire.

1. The correct way to connect.

When connecting wires, the first thing to pay attention to is that the connection method should be correct, and the joints should be avoided as much as possible, because the joints are easy to have relatively large resistance, which is easy to cause the wire to heat up. If the joint cannot be avoided, the joint should be wound firmly with insulating tape to avoid potential safety hazards.

2. Choose a reasonable installation form.

When connecting the wires, you should choose the most suitable installation method. Wire installation can be divided into surface-mounted and surface-mounted, which refers to the wiring installation along the surface of places such as ceilings and walls. The concealed installation refers to the wiring installation in the ceiling or wall, pay attention to the installation of the line can not be squeezed and folded, and need to ask professional construction personnel to help, so it is safer.

Concatenation. The switch should be installed on the front, the upper end is the incoming line, and the lower end is the outgoing line. Under normal circumstances, the ground wire does not enter the switch.

When the current of the line in the home is overloaded, the overload current causes the heating element to generate a certain amount of heat, prompts the bimetal sheet to bend upwards when heated, and pushes the lever to disengage the hook from the lock.

When the short circuit occurs in the line, the short-circuit current exceeds the instantaneous trip setting current value, and the electromagnetic tripper generates suction, sucks the armature and hits the lever, so that the hook rotates upward around the shaft seat and disengages the lock, and the lock breaks the three main contacts and cuts off the power supply. The two-phase air switch is also known as the 2P air switch, if the air switch is not marked L and N, then it is good to wire according to the habit of left zero and right fire.

How do you wire an air switch without any markings? The old electrician will teach you step by step, practical electrician technology!

Air switches are commonly used in the family 1P and 2P, and the wiring is shown in the figure below

The wiring method of the air switch is probably to distinguish the wires first, then connect the indoor wires, and finally connect it with the entrance wires.

Before the air switch is wired, first we need to distinguish the different wires. Because they represent different colors, it is more correct to use an electric pen to distinguish between live wires, neutral wires, and ground wires. Because the live wire has a voltage value, but the neutral wire does not.

Next, it should be noted that the switch should be installed on the front, the top is the incoming wire, the lower is the outgoing wire, and the ground wire does not need to enter the switch.

Distinguish the wires, prepare a distribution box, if not, you can use a card slot that can fix the air switch instead of the card slot, fix it on the wall, and then install the air switch on the card and hail slot. Then start wiring, to connect the indoor wire, because the switch has a corresponding mark, if there is the letter n, it needs to be connected to the neutral line. Finally, you need to connect it with the incoming wire, and see that it has a letter n, which corresponds to the neutral line, and the binding post corresponding to A2 needs to be connected to the live wire.

Socket wiring method

The socket wiring method includes single-control single-open switch connection method, single-open five-hole socket wiring method, single-open three-hole socket wiring method, etc. The switch is used to control the on/off of the power supply of the socket, and can be wired according to the following methods. Connect the live wire to the L terminal of the switch, connect the L1 terminal of the switch with the L terminal of the two-pin socket, and connect the neutral wire to the N terminal of the socket.

The switch is used to control the lamp, and the socket is controlled without opening and closing. The wiring method is to connect the live wire to the L terminal of the switch, connect the L1 terminal of the switch with a terminal block of the lamp head, connect the zero wire to another terminal block of the lamp head, and the switch forms a loop with the lamp. Then connect the live wire to the L terminal of the two-pin socket, and connect the neutral wire to the N terminal of the receptacle, and the two-prong socket becomes another circuit.
