Questions about replacing the air switch?

1.Yes, the air switch should be disconnected to replace the main switch in your home for safety.

2。Although the total power is so large, but the probability of simultaneous use is very small, there is a problem of simultaneous use of coefficient, according to the coefficient calculation of only more than 4000W, which is a very high coefficient, with 20A on the line. Of course, it also depends on how big your home line is, if it is less than 4 square meters, you can only use a smaller empty opening, otherwise it will not jump when it exceeds the safe current carrying capacity of the wire.

If it is a 4 square line, you can use a total switch of 20-25a, correspondingly 6 square with 32a, 10 square... It is impossible for an old house to use such a big one.

3。Many old houses are home appliances that are not grounded, and it is of course better to use a leakage circuit breaker.

1. Pull down the main electric switch at home to replace it safely, and it is best to use an electric pen to measure it.

2. Select C32

3. Of course, choose an air switch with leakage protection, which is recommended by the above professional electrician.

The selection of the air switch should be considered according to the rated current of the load, not how many times larger, because the air switch has considered the overload multiple, and the single-phase leakage switch of C25 is estimated to be 5 kilowatts per kilowatt per amperere, and the brand such as Meilan Rilan, etc., the overload current of type C is 5-10 times the rated current, after the air switch is connected. It is safer to stop for a few minutes and open the upper line of the whole building.

1.It is best to pull down the main switch downstairs and replace the knife switch at the door. If the main switch downstairs is not convenient to pull down, you can connect the empty switch behind the knife switch (pull the knife switch down first), which is safer.

2.Choose C32 leakage circuit breaker.

Summary. Hello dear, of course, is to find the front end box to close the main switch. If you can't find it, you can do the following.

1. Turn off the power and remove all the cables below. 2. Standing on the insulating table, if the electrical box is metal, pay full attention to the operation action should be small. 3. Remove the live wire, wrap it with insulating tape and put it in a place where it will not be touched.

Remove the neutral wire again, after which the switch can be replaced. 4. After the new switch is fixed, connect the upper and lower end lines and the neutral line first. Finally, just connect the live wire.

Hello dear, of course, is to find the front end box to close the main switch. If you can't find it, you can do the following. 1. Turn off the power and first take all the connections below the mold under the cherry blossoms.

2. Standing on the insulating table, if the electrical box is metal, pay full attention to the operation action should be small. 3. Remove the live wire, wrap it with insulating tape and put it in a place where it will not be touched. Then take the cavity code hall under the zero line Wu Yin, and then you can replace the switch.

4. After the new switch is fixed, connect the upper and lower end lines and the neutral line first. Finally, just connect the live wire.

This kind of thing. Yes, follow the steps above.

1. The first is to cut off the power supply, which is the top priority and involves personal safety.

2. Wire removal, wire removal should be marked at the same time, in order to restore, if the wire is found to be burned, should be replaced with the same specification of the wire.

3. Remove the broken switch and replace it with a new switch, which is a card slot type, which is very convenient to install and disassemble.

4. Restore the wiring, pay attention to the wiring must be firm and reliable, tighten the wires of other unreplaced switch wires, and the joint may be relaxed after a long time, and many faults are due to the poor contact caused by the relaxation of the joint and the heating and burning of the switch.

5. Power on, try to cast the switch three times, and it can be used normally without any problems.

First turn off the main switch, remove the shell of the air switch box after the power is off, then carefully remove the faulty air switch, then install a new air switch, rewire according to the original wiring method, pay attention to insert the wire into the card slot of the terminal hole, and tighten the screws.

The specific steps are as follows:

1. First turn off the main switch.

2. To remove the faulty air switch, you need to use a flat-mouth screwdriver to insert it into the small hole under the air switch, and gently pry it down.

3. Install a new switch.

4. After the switch is installed, re-wire it according to the wiring method on the original switch.

5. Finally, check whether all the lines are connected, install the air switch box, and turn on the power.

Notes:1. When proceeding to step 2, pay attention to loosen the screws of the upper and lower power interfaces, take out the connected wires, and then fold the air switch.

2. When installing the new air switch back, you must hear the sound of Kata, so that it is installed.

If the inlet line can't be turned off, change the switch without the experience of an electrician to close it first, or don't do it blindly! One is at risk of electric shock, and the other is at risk of interphase short circuit! In the case of ensuring your own safety, stand on the stool, but the person must stand firm, and there is a guardian next to him...

Remove the original bad air switch, it is best to remove the upper inlet wire one by one, or remove one with adhesive tape! When wiring, do not touch the contacts on the edge, otherwise there will be a serious short circuit, and there will be sparks and ** sound! Don't touch wires on any part of your body...

It's best to get an electrician to explain the situation and let them help you change!

First turn off the main power supply, and then cut off the switch decorative cover, which will expose the two link screw holes on the switch, use a Phillips screwdriver to remove the switch from the junction box, remember the wire access point, and then remove the wire and connect the new switch.

I hope my answer can help you.

First dismantle the fire wire, wrap the insulating tape, and do whatever you want with the rest of your love. Precautions: When disassembling the live wire, do not let any part of your body touch the wall and floor to prevent electric shock.

You can also do a good job of self-insulation, such as wearing insulated gloves and insulating shoes. In the end, I advise you to find a professional, after all, you have not been engaged in electrician maintenance, and you have not undergone professional skills and safety training.

Take the pliers to wiring the wiring so that the power will not be cut off

It doesn't matter, when I was fifteen years old, I was charged to the wire, as long as my shoes were not wet and my body did not touch the neutral line or the wall when I touched the fire wire.

First try to see if the air switch is able to disconnect and close, if the mechanical part is normal. Then the next step, find a multimeter, measure the switch in the closing and disconnecting state, if possible, energize the switch, check whether there is voltage at the lower port of the switch after disconnection and closing, and whether the voltage is normal.

Under normal conditions, the armature of the overcurrent tripper is released; In the event of a serious overload or short-circuit fault, the coil connected in series with the main circuit will generate a strong electromagnetic attraction to attract the armature down and jack the locking hook, so that the main contact is disconnected.

The undervoltage tripper works on the contrary, when the voltage is normal, the electromagnetic suction pulls the armature and the main contact is closed. In the event of a severe voltage drop or power failure, the armature is released and the main contact is disconnected. When the power supply voltage returns to normal, it must be re-closed before it can work, and the voltage loss protection is realized.

That air switch is broken, tell the property and let them fix it - that's their jurisdiction, at least they have the responsibility to contact the power department. It's not safe to connect them casually. The indoor ones are your own business, and the outdoor ones don't have to pay for them.

Take care of your own meter box at home, do you call the power bureau to prepare for the salary? If there is a leakage of electricity at home, it will also trip, and it will not be able to close the gate if you don't press the blue square below. Of course, if there is indeed a leakage, it will trip again if the fault is not eliminated.

It is recommended that you turn off all the lines first, and then open all the way, and drive to which way to trip is that the road is leaking, and then find a way to solve it.

Look**, your air opening is a 1P+N leakage air switch, only the live wire has overload and short-circuit protection, the LE in DZ47LE stands for the leakage accessory is electronic, the so-called electronic type is leakage protection is electrically controlled, that is, there is an electronic circuit. According to your description, the empty opening does not connect the load and trips, obviously the leakage accessories are damaged by the electronic components, and the leakage protection accessories of the same specification need to be replaced. Open the terminal cover under the circuit breaker, remove the wiring, open the connecting buckle, remove the leakage accessory, or take the entire empty open to the appliance store, and they will help you replace the leakage accessory.

This means that your line is short-circuited, and the electricity bureau will charge for it.

It should be that the switch is broken, it doesn't cost much to replace one, it is good to install, and safety first.

How much does it cost you to change an empty open Safety first.
