Can air switches and leakage switches be installed with parallel circuits?

Switches are a common object in life, and air switches are mainly used to monitor the current in the circuit. If the set value is exceeded, it jumps and cuts off the circuit. Tripping occurs whether the current is due to excessive electrical power, electric shock, or damage to the insulation

For example, the air switch is set to 32A, about 7000 watts, and when this current is exceeded, the air switch trips to form protection.

The air switch is generally installed in the distribution box as the main switch and the branch switch. We all know that under normal circumstances, the current current from the live wire into the electrical appliance, and then from zero In this case, the current of the live wire and the neutral wire should be equal, or not much different, but if the electrical damage occurs, the insulation effect is not particularly goodWhen we touch these areas, the line of fire enters the present part, through our body into the earth, from the zero line, which will reduce the flow of current, and the leakage protector can detect changes and quickly cut off the circuit, protecting us from the danger of electric shock.

Therefore, the leakage protector is very sensitive and will disconnect in time as soon as it detects the current error between the live line and the neutral line. So his settings are usually a few hundred or tens of milliamps. Very small values.

In addition to the leakage protector installed in the air switch position, sometimes it is also installed in some electric water heaters, small kitchen treasures and other equipment, which is prone to leakage。Reduce defects. Two should not be pressed at the same time, to tell you clearly, both must be pressed at the same time because the two functions do not overlap.

Air switches are used to monitor high-power appliances. Prevent overloading of wires and tripping. The leakage protector is to prevent leakage, protect personal safety and trip.

In summary,An air switch and a leakage protector must be installed at the same time, both of which have a role to play. Nowadays, many air switches have leakage protection on them, so you can buy an integrated one.

It is not possible to use parallel connection, if there is a problem in this way, it is more troublesome to repair. Then everyone must choose *** when choosing the switch.

It's better not to connect them in parallel, because there is a problem with the parallel circuit, and it is very troublesome to renovate, so it is better to install them separately.

It is not possible to install in parallel, which is only convenient at the time, but if there is a problem later, it is difficult to repair, and the maintenance cost is also very high.

It cannot be installed in parallel, it should be used in series, because this can play a double protection, and the air switch is equipped with protective measures, which can improve safety.

It cannot be installed in parallel. It is best to let the electrician install the switch, which can give more professional advice and facilitate long-term use.

It can not be installed in parallel circuits, which is a bit dangerous, can not ensure the safety of the line, and is more troublesome during maintenance.

It is not possible to connect in parallel, and after learning the circuit, you know that the series connection is mutually restrictive, and the parallel connection will not affect each other.

It shouldn't be convenient to use parallel connections. However, when installing the switch, try to ask the installation master to help install it, so that the installation effect is better.

Installation method of leakage switch before air switch: Most of the installation methods of leakage switch before air switch are based on leakage switch, and the sub-power switch of each circuit is air switch. Some air switches apply 2P, 1P, and 1P+N; As the main switch, the leakage switch is assembled before the air switch.

I've tried to find its advantages, but it's hard to say what this type of installation is.

As the main switch assembled before the air switch, the defects of the installation method are indeed very obvious: first, if the route produces a common fault of leakage, the main switch will jump, which will disconnect all the electrical works at home, and the application is very inconvenient; Secondly, if there are common faults of leakage in the route, it must be cleared in each circuit, because only the main switch in the circuit is leakage maintenance, so it will be very inconvenient to clear the common faults; Eventually, it is also prone to operational errors, especially for lighting fixtures in circuits, because the amount of leakage current in household leakage switches is usually 30mAh, so it only needs to reach 30mAh in the total amount of leakage in the circuit, and it will be powered off, sometimes only a few mAh of leakage in a single circuit.

In daily life, it is accurate to assemble a leakage switch behind the air switch. Its installation method: The installation method of assembling the leakage switch after the air switch is the most frequently used now, and it is also the recommended way for home furniture.

It takes the 2P air switch assembled in the front as the main switch, and then the air switch assembled on the front lighting circuit as the main switch, in addition to the lighting fixture circuit, the installation method of the leakage switch has significant advantages.

When a circuit is leaked, only the circuit is powered off, and the main switch is not easy to be powered off and is not easy to affect people's applications; Secondly, because each jump corresponds to the sub-power switch, it is very easy to find out which circuit has common faults, and it is also very convenient to clear the fault; Ultimately, it's not prone to operational errors; As the main switch, the air switch is assembled on the front side, and the leakage switch is used on the rear side, except for the lighting fixture circuit. The estimated cost is high, and the space occupied is relatively large.

The air switch is connected to the power supply first; The air switch should be placed on the main switch, and then the leakage switch should be connected in parallel.

When decorating at home, the air switch and the leakage switch, which can be installed first, in fact, it does not affect, but when installing, you must ask a special electrician to come to the door to install.

Of course, let the air switch be connected to the power supply. It is necessary to use an air switch to make the main power supply, and then use a leakage switch to make a shunt switch, so as to ensure that the use of the circuit will not be affected by any factors.

The previous leakage switches did not have short-circuit protection, that is, there was no air switch function. The current leakage switch is a combination of the two, that is, it has the function of leakage protection, and also has the function of overload and short circuit protection. However, there is still a difference between the use of air switches and leakage switches, especially for our household ones.

Commonly used air switches and leakage protectors are shown in the figure below. This is called the air switch, the air switch is mainly to monitor the current in the line, if it exceeds its set value, it will jump away, cut off the circuit, whether the current is due to excessive electrical power, or electric shock or insulation damage, will jump away.

The air switch lacks an important protection function – leakage protection. This point can be made up by the leakage switch - the leakage switch and the air switch are only possible in terms of function, and only possible people will feel the difference, that is, the leakage switch has a leakage protection function. Therefore, in circuits prone to leakage, it is necessary to use leakage switches.

For example, the setting value of the air switch is 32A, which is about 7000 watts, and when the current is exceeded, the air switch will trip to form protection.

It has the functions of overload protection, short circuit protection and leakage protection, and conforms to GB standard. Both circuit breakers are suitable for use in domestic and similar settings, they are designed for use by non-professionals and do not require maintenance. Air switch and leakage protector are necessary for electricity safety in the family, and the two switches can achieve different protection functions, so it is not a question of whether they can be installed at the same time, but must be installed at the same time to ensure the safety of electricity.

Let's explain the two types of switches.

The choice of air switch and leakage protection, many friends are estimated to have been fooled by the decoration team, and tell you that the home is equipped with leakage protection, in fact, it is simply a lie to you, the air switch and leakage protection are selected according to the function we use, and the home miscellaneous altar will give you a good talk about how to install the air switch and leakage protection.

Yes, it can not be installed at the same time, it should be installed at intervals for a period of time, if it is installed together, there may be very bad things, you must pay attention to it when decorating.

These two cannot be installed at the same time, because they affect each other and are easy to induce unsafe accidents, so the air switch should be installed after the leakage switch.

Personal opinion, if there is any error, please correct. The function of the empty opening is: ** There is a short circuit, overload and other situations in the road, and the current is cut off immediately to protect personal safety; The leakage switch has the function of empty opening, and there is an additional leakage protection, which is a protection function for the leakage of lines and electrical appliances.

For household electricity, it is recommended that the main gate be open empty (double horse), the light should be open empty (single horse), and the socket leakage protection (double horse).

Because these two devices are in a contradictory state, but the necessary one can be installed according to the needs of their own home, most people still choose to install air switches.

Both can be installed at the same time, so as to ensure that our electricity process is safe and secure. Be sure not to install it privately, but let someone who knows how to install it yourself.

Yes, it can be installed at the same time. When the specific operation is carried out, the air is installed first, and then the leakage is installed, so as to ensure that the power can be quickly cut off when the current runs out.

It is not necessary to install the air switch and the leakage switch at the same time. Because of the air switch, it contains all the functions of the leakage switch. As long as we are choosing those that have a brand guarantee, ** more expensive air switches. That's it.

Yes, this operation requires a professional person to operate it to ensure that both devices can be used normally.

The respective functions of the air switch and the leakage switch: the function of the air switch itself is to open and break the circuit, and then it also has at least two protection functions, namely short-circuit protection and overload protection, and there is also an optional function is under-voltage protection; The leakage switch also has an on-off effect, and the width is an important factor that must be considered in the design of the distribution box - the width of the box determines the size of the wall opening. It's not just about aesthetics, it's about building structure.

The width of the distribution box is determined by the width of the circuit breaker in the distribution box.

When the human body touches these parts, an electric current flows through the human body to the earth. At this time, the zero-sequence current transformer in the leakage circuit breaker will detect the existence of residual current, and after the residual current reaches the action value, the residual current relay will act to trip the circuit breaker. In turn, the current flowing through the body is disconnected.

It plays the role of leakage protection. The leakage protection is based on the chip, generally the chip will be after a main pair of windings, once the main winding is put here to sound a leakage accident, the secondary winding will produce voltage to push the built-in mechanism, and then produce the effect of tripping.

In fact, the leakage switch is composed of an air switch and a leakage module, as the name suggests, the leakage switch must include the function of the air switch, then many people will have questions, since the leakage switch has the function of the air switch, why not use the leakage switch directly, and also make the air switch out of the leakage switch is to prevent the live wire or neutral line from the rapid induction and trip protection device, such as the circuit of the short circuit to be opened by the air and responsible.

Their working principle is different, the structure is also different, if all the air openings are replaced by leakage protection switches, it will bring a problem that the width of the box of the distribution box will be very wide, which determines the size of the wall opening, which not only affects the aesthetics, but also related to the building structure. The width of the distribution box is determined by the total width of the air circuit breaker in the distribution box, and the air open is also called the circuit breaker, which is a replacement product of the old electric switch, with over-current protection and short-circuit protection function, which can realize the automatic tripping of over-current.

This is to have a double insurance, and if the short-circuit protection does not work accordingly, the air switch can also prevent leakage.

Because the air switch is to prevent a fire from a short circuit, similar to the effect of a fuse, the effect is very large.

Mainly to protect the wiring in the whole house, in order to prevent fire caused by excessive voltage and **, for safety reasons

In fact, this is a double guarantee for the family, which can make our lives happier and safer.

Home circuitsYesAt the same time, install an air switch and a leakage protector.

The leakage protector is mainly used in the event of leakage failure of the equipment and the protection of personal electric shock with fatal danger, with overload and short-circuit protection functions, which can be used to protect the overload and short circuit of the line or motor, and can also be used as an infrequent conversion and start of the line under normal circumstances.

Leakage protector can be classified according to its protection function, structural characteristics, installation mode, operation mode, number of poles and wires, action sensitivity, etc., here it is mainly described according to its protection function and use, and can generally be divided into leakage protection relay and leakage protection switch.

and leakage protection sockets.

Leakage switches and air switches are collectively referred to as air switches. The former is protected against leakage, and the latter is not.

Air switches without leakage protection are used for main switches and lighting lines, while air switches with leakage protection are mostly used for socket lines.

The air switch without leakage protection belongs to the overcurrent insurance, that is, the current on the line exceeds the rated value of the air switch and trips instantly, while the air switch with leakage protection can trip in an instant only in the case of zero and live wire current inconsistency, that is, leakage (this value is generally set to 30 mA, that is, the difference). The two cannot be mixed, otherwise, they will not play a protective role.
