The wires buried in the wall are connected to the air conditioner, and they are broken by nails, can

It is not recommended until the wire has been replaced.

The wire that has been nailed by the nail means that its insulation and protective layer must fail, and then it is easy to cause a short circuit in the case of high current.

The instantaneous change of current and voltage caused by a short circuit may cause unnecessary damage to the electronic components of the air conditioner, that is, the motherboard, or even directly cause the motherboard to break down.

Of course, it can't be used, and the wires must be replaced before they can be used normally.

Hello! If the nail does not break through the two wires and does not cause a short circuit, then there will be no problem, but it is also necessary to prevent the wall from getting wet, otherwise there may be a leakage accident.

It's very dangerous, and it is not recommended to use it again after the cable is broken, and there are too many unsafe factors.

It is estimated that the nail causes the wire insulation skin to be damaged and causes a short circuit, although it can still be energized, but there is a great safety hazard, the short circuit will ablate the wire, and the possibility of another short circuit or leakage will occur after the damage is very large.

Therefore, the wires should be overhauled or replaced in time.

In this case, the cable must be broken . It is highly recommended to cut off the power first, make the nail hole bigger, and wrap the broken cable.

Hurry up and break the wall to check, it will not be short-circuited for the time being, maybe the wire skin is broken, and the work heat may be short-circuited? Danger, deal with it.

I hope that this set of wires is a live wire, and the old wires will be pulled out and replaced with new wires to continue to be used.

There will be. If the outer skin of the wire is broken and it comes into contact with the metal inside, it will be connected to electricity.

The air conditioner punch hole is relatively small, and it is not easy to connect the wire if it is broken, even if it is well connected, it is estimated that it will not be connected firmly, so it is necessary to pay attention to potential safety hazards.

Generally safe, worrying. The master has connected the broken wire and insulated it. Again, the walls are relatively insulated. FYI.

Haven't you ever seen someone take a wire? Originally, after connecting the wire back, it would be a pity to wrap the outside with insulating tape a few times.

As long as it is connected correctly, it will not loosen, and the adhesive tape must be tied tightly, and the screw ...... can not be driven in

It should be tightened to avoid heating and burning the wire with high electrical power and causing accidents.

The black tape is insulating, so it is safe.

It's okay, just pick it up as long as no one touches it.

Just wrap it up, uneasiness is a psychological problem.

If it's an electrician again, it's no problem, and the wiring is also required.

The joints should be firmly connected and the adhesive tape should be thicker.

It's not a big deal, but that's all it takes.

That's the only way to do it, otherwise you want to start over?

If the line in the wall did not pass through the pipe before, it is impossible to pass through it now, and can only be slotted in the wall or walk the open line, if there is a pipe that can be worn.

If in the case of the previous electrician installation specification, the right side (L) of the live wire access socket, and the lighting switch are controlled live wires, the exchange of live wire and neutral wire is not safe, and the switch controls the zero wire, and does not cut off the live wire, causing the lamp head to be directly electrified. I haven't seen or heard of any instrument that can find the broken wires in the wall! With megaohms.

The pipes and wires connecting the air conditioner to the indoor unit and the outdoor unit should not be buried in the wall. Because in the future, when the service life of the air conditioner is up, the wall will have to be chiseled; In addition, it is not conducive to maintenance.

Tube for air-conditioner and refrigerator is a metallurgical term published by the National Committee for the Examination and Approval of Scientific and Technological Terminology in 2019. Pipes with good heat dissipation performance for air conditioners and heat exchangers in refrigeration systems.

Air conditioning refrigerant pipe refers to the pipeline connecting heat exchangers, valves, compressors and other major refrigeration components through which the refrigerant flows in the air conditioning system. Copper pipes are usually used.

The air conditioning system transports cold or heat to the end, and divides it from the medium conveyed, there are several ways, one is to directly supply air, one is to transport hot and cold water, and one is to directly take the refrigerant. For systems with direct air supply and hot and cold water delivery, the refrigerant lines are generally concentrated in the vicinity of the main engine. For systems that run directly through the refrigerant, such as VRV systems, the refrigerant duct will go directly into the air-conditioned space and connect the outdoor main unit to the indoor unit.

The refrigerant line is long. The refrigerant pipeline is too long, and the expansion valve generally adopts the external equilibrium mode to cope with the pressure drop from the evaporator inlet to the compressor suction port. The refrigerant pipeline is a pressure-bearing component, and its burst pressure should meet more than 5 times of the operating pressure, or more than 3 times the maximum possible pressure.

Generally speaking, there is no problem, it is impossible to guarantee that you will not destroy the wall in the future, and if it does, it may lead to refrigerant leakage.

It is better not to bury it in the wall, which is not conducive to repair.

The copper pipe of the air conditioner is used by the external compressor to transmit the refrigerant to the indoor unit, and the compressor sends the refrigerant color to the evaporator of the indoor unit, and uses the internal fan to emit it, as long as the copper pipe is damaged and leaks, the air conditioner cannot be used.

Let the air conditioner repair replace the copper pipe and wire for you, or weld the copper pipe to make a good insulation layer, which can be used.

There are several possibilities that the nails may be nailed to the place where the wires are walked: 1. The outer skin of the wire is nailed, resulting in a short circuit between the wires and empty tripping;

2. The wire is broken, leakage to the ground, and the leakage switch will trip frequently;

3. The wire is nailed off, and there is no power supply in the back line.
