What should I pay attention to when installing the leakage protector and the junction box of the air

There can be no water or dust, and it is necessary to do a good job of moisture-proof, waterproof and dust-proof measures on site, and pay attention to the actual operation of the site. If the equipment consumes a lot of power and the internal temperature is high, such as in summer, it will easily accelerate the aging of the equipment and even cause damage.

The line through the leakage protector can not be shared with other lines or other leakage protectors, otherwise a failure will occur, in short, the circuit through the leakage protector can only be used alone.

Pay attention to the wrong connection of the zero fire, and some of them are single-broken!

It depends on whether you install the wire outdoors or indoors, and the requirements are different.

The installation method of the leakage switch before the air switch: The installation method of the leakage switch before the air switch is basically the leakage switch as the main switch, and the sub-switches of each circuit are the air switches. Some air switches use 2P, 1P, and 1P+N; As the main switch, the leakage switch is installed before the air switch.

I've tried to figure out the advantages of it, but it's really hard to say what is good about this installation method.

As the main switch installed before the air switch, the shortcomings of the installation method of the leakage switch are indeed very obvious: first, if the line leakage fault occurs, the main switch will jump, which will cut off all the power in the home, which is very inconvenient to use; Secondly, if there is a leakage fault in the line, it must be eliminated in each circuit, because only the main switch in the circuit is leakage protection, so troubleshooting will be very troublesome; Finally, it is also prone to misoperation, especially the lighting in the circuit, because the leakage current of the household leakage switch is basically 30 milliamps, so as long as the sum of all the leakage in the circuit reaches 30 milliamps, it will trip, and sometimes the leakage of a single circuit is only a few milliamps.

In everyday life, it is only right to install a leakage switch behind the air switch. Its installation method: the installation method of installing the leakage switch after the air switch is currently the most commonly used and the recommended method in the home field.

It takes the 2P air switch installed in front as the main switch, and then the air switch installed on the front lighting circuit as the main switch, in addition to the lighting circuit, the installation method of the leakage switch has obvious advantages: first, when a circuit leaks, only the circuit trips, and the main switch will not trip, will not affect our use; Secondly, since each time the corresponding sub-switch is jumped, it is easy to find out which circuit is faulty, and troubleshooting is also very convenient; Finally, it won't be misoperated; As the main switch, the air switch is mounted at the front, and the leakage switch is used at the rear, except for the lighting circuit. It is expected to be more expensive and take up more space.

It should be installed in the front, in the case of moisture damage to the air switch, leakage may occur, so the leakage protector should be installed before installation, and the power supply should be cut off before installation to ensure its own safety.

I think the leakage protection machine should be installed behind the air switch, we should install the air switch first, and then install the leakage protection switch; It should be noted that when installing the line, the air switch should be mainly worked, and the switch leakage switch should be used as an auxiliary switch, and the correct connection method should be the air switch and the leakage switch.

It should be installed in the back, and it should be noted that the leakage protector must be selected with good quality, high power and the highest sales. There should be capacitance and capacitance inside.

Electromagnetic induction leakage circuit breaker means that the coil around the copper wire will be magnetic. Leakage switch is powered off.

The power genuine is from this magnetic force. There is a coil up and down the right switch (one for the live wire and one for the neutral wire), usually when the electrical appliances are used correctly, the zero live wire has a current through, and the upper and lower coils have a magnetic balance force, so the switch is not automatically disconnected, but once a leakage occurs (the leakage is that the live wire passes through a conductive object and does not return to the zero line.

For example, if a person is electrocuted, the current of the live wire passes through the human body and then flows into the ground) The live wire has a current through, but because there is no loop, there is no current through the zero line, so only the coil of the live wire undergoes electromagnetic induction, and the magnetic force is generated to cut off the power-off switch.

The switch is placed in front and the leakage protection is an auxiliary module that is installed behind the circuit breaker. It is recommended to buy a switch with leakage protection

I think ah, you can buy an air switch with leakage protection, which is the integrated kind.

Switches are available in every family, many switches will leakage during use and are unsafe, air switches with leakage protection are more popular switches in recent years, which have received a lot of attention, butAir switch with leakage protection1. The continuous power can be used with a relatively large electrical appliance, and then at the same time you can use the shockproof hammer to hit the buried place of the wire that you tied tightly with adhesive tape and oil paper bag, if it does not trip, it means that there is no problem.

2. It is recommended that the whole wire should be replaced, if you do not want to replace the whole wire, then it is recommended that you can connect the terminal head to the nearest cassette such as switch, group socket, etc.) If it trips, then you touch the air with your hand to see if it is hot, if it is hot, then it is a short circuit of the wire.

3. If you are multi-way empty open. If it is a split jump, take the air opening without leakage protection as an example, then it is even simpler, that is, your wire is short-circuited.

4. If the air is open with leakage protection, or divided into multiple empty opens, then you can do this, (the ground wire in your home is always connected) knock you on the tile and accidentally knock the wire through those few places of electricity, and connect it to see if it will jump if it is open without the hidden protection of the leakage wheel, if it will trip, it is a short circuit of the wire. If you don't jump. So will you jump on the air open with leakage protection, if you jump, then it is the electrical appliances or circuits in your home or hall.

5. I don't know if you connected the switch at home yourself? I don't think it would have been for you to pick it up yourself. Then the electrician you hired is terrible.

You can't use electricity at home. What a shame for the electrician's face! If that's the case, you can.

Disconnect your electricity from those broken places. Turn on the switches you suspect if they are empty and will trip.

Will the air switch with leakage protection trip if it is not connected?

It is definitely not possible to add a leakage module when connecting two live wires at the same time, because the working principle of the leakage module is to detect the total vector sum of the loop! Whether it is 2P or DPN series, there will be a situation of tripping when the power is on, and the sum of the two live wire vectors is not zero, so the result of connecting two circuits on a 2P or DPN circuit breaker is that there is a problem with one circuit. Therefore, the two holes of 2P and DPN are connected to the 101 fire of one circuit under normal circumstances, and both circuits are affected at the same time, and both circuits are broken at the same time.

The above is how to wire the air switch with leakage protection, and the air switch with leakage protection has a detailed answer to whether it will trip if it is not connected, I don't know if you are satisfied with our introduction.

Three-phase four-wire leakage switch, the shell has a symbol to mark the position of the neutral line and the phase line, and it must be wired in order.

Single-phase leakage switch, the shell is marked (L), (N), should be wired according to the mark.

Most single-phase leakage switches and air switches do not have specific symbol markings, and in practical applications, experienced electricians follow them"Left zero right fire"The law to wiring.

Continuous electricity power can be used with a relatively large electrical appliance Then, while using electricity, you can use a shockproof hammer to hit the buried place of the wire that you tied tightly with adhesive tape and oiled paper bags, if it is not tripped, then it means that there is no problem there (I suggest that the whole line is best replaced, if you don't want to replace the whole wire, then it is recommended that you can connect the terminal to the nearest cassette, such as a switch, socket, etc.), if it trips, then you use your hands to touch whether the air is hot, if it is hot, then it is a short circuit of the wire, and second, if you are a multi-way empty open If it is a split jump (take the air open without leakage protection as an example), then it is simpler That is, your wire is short-circuited Third, if your air open with leakage protection, or split into multiple empty opens, then you can do this (your home ground wire is always connected) knock you on the tile and accidentally knock the wire through those few places of electricity Connected to the air without leakage protection to see if it will jump If it will trip, it is a short circuit of the wire If it does not jump, then you will not jump on the air open with leakage protection If you jump, then it is a leakage of electrical appliances or circuits in your home Fourth, I don't know if the switch in your home is connected by yourself? I think if you don't pick it up yourself, then the electrician you hired is so bad that you can't handle household electricity, and it's really embarrassing for the electrician! If that's the case, you can disconnect the electricity that you knocked out of those places, and turn on the switches that you suspect are empty and tripping.

Up in and down out, the zero line is marked. The two leakage protectors without remarks can not be separated from the neutral wire.

Where there is leakage, it will trip, and the electrical appliances under the switch will be cut off one by one to check which fault it is.

It is enough to have an air open with leakage protection, no need to use an air switch, the air open with leakage protection has overload and short circuit protection functions, and it is a waste to install an additional air open.

As with the general switch connection, the leakage needs to be paid attention to is that the outgoing line should be directly connected to the load, and there can be no zero-ground mixing.

The zero line outlet of the air switch with leakage protection is burned, which is generally caused by the fact that the screws are not tightened.

Treatment: Disconnect the air switch, scrape the wiring to be burned, rewire, and tighten. If it burns out, the only thing to do is to change the air switch.

The live wire on the load side of the touch leakage protection switch is not allowed, and if the leakage action current of the leakage protector is greater than 30mA, an electric shock accident will still occur.

Therefore, under no circumstances, the firewire is not allowed.

If you want to achieve normal electricity consumption in the family, you must not only arrange and select the fine circuit according to the specification, but also need to install a lot of protection devices, switches, etc., usually the home distribution box needs to install two kinds of switches, namely leakage protector and air switch, these two switchgear have different roles and are indispensable, but it is more troublesome to install two kinds of switches, so the air switch with leakage protection will be selected, so how to wire the air switch with leakage protection? Let's take a look with Qeeka Home experts.

1. How to wire the air switch with leakage protection.

First of all, install a 60A air switch on the bus, it is not necessary to install a leakage protector, the leakage current is installed on the branch of each layer, to choose 40A, or directly install a 40A air switch with leakage protection on the branch line of each layer, it should be noted that the specifications of the zero line and the live wire should be consistent, and the air switch is best to use a bipolar one.

2. How to choose a leakage protection switch.

1. Buy regular products.

The installation of leakage protectors must be selected from regular manufacturers, and there must be a product quality inspection certificate, because there are many inferior leakage protectors on the market, and the installation of this product is easy to cause inconvenience such as tripping and electric shock and other safety hazards, which is very unfavorable.

2. Check the parameters.

In the installation of leakage protection switch, it is necessary to check the power supply voltage, working current, leakage current, action time and other parameters, which has a great impact on the safety of people and equipment, and it is best to choose a leakage protector with high sensitivity and fast action.

3. Do hierarchical protection.

The rated leakage current of the upper leakage protector is greater than that of the rated leakage current of the next leakage protector, which can avoid skipping tripping, and can also narrow the scope of accident inspection, which can be said to protect the safety of people and equipment.

Summary: The above is the introduction of how to wire the air switch with leakage protection, I hope the content shared can give you some reference, if you want to know more about relevant knowledge, you can **** Qeeka Home to consult.
