Wire Problems Problems with wires at home, what should I do if the wires at home touch the wires?

The difference between wire and cable The method of finding the difference between wires found in the cable network 1. Wire: It is composed of one or several soft wires, covered with a light and soft sheath, and is used to carry the current of conductive metal wires. There are various forms such as solid, stranded or foil braided.

According to the insulation status, it is divided into two categories: bare wires and insulated wires. 2. Bare wires that do not contain any insulation or protective layer. In addition to being used as a conductor for the transmission of electrical energy and information, it can also be used to manufacture components and connecting wires for electrical appliances.

Generally, it is made of copper, aluminum, copper alloy, aluminum alloy and copper-clad steel, aluminum-clad steel and other composite metal materials. In addition to good electrical conductivity, bare wire also has certain mechanical properties, such as tensile strength, elongation, bending and torsional characteristics, creep resistance, wear resistance, etc. 3. Insulated wires, which are divided into magnet wires according to their uses

A: As long as you buy a single-phase input welding machine, there is no problem. You don't look at the current to be so high, that is the output current of the welding machine after the low voltage, when you buy the welding machine, the load index is mainly the power consumption, the general power consumption of the welding machine is less than a few kilowatts, and the meter wires at home are generally no problem.

In addition, I would like to remind you that you should not buy a 380V three-phase welding machine, because there is generally no three-phase electricity at home.

For example, in the figure above, the input is only 9,000 watts, which translates to just over 40 amps.

With such a large current, the household cable socket will definitely not be able to reach it.

The embedded cable in the household is generally a cable of 4 square or less than 6 square meters, and the maximum current carrying capacity is about 30 to 40 amperes.

This kind of welding machine should not be suitable for home use.

According to the current carrying capacity meter, at least 25 square wires should be used.

The entrance line of the household is generally 10 to 16 square meters

This kind of welding machine is not suitable for use at home.

The meter wires in the home will never reach such a large current as 100A! Now after the expansion, the maximum capacity of the home meter is 40A to the end, and the 100A can only be connected to the line from the outdoor transformer!

100A requires 16 square copper wires, so you can see if you can use it by looking at the square number of your home wires. If it is less than 16 square meters, change the line or merge a set of lines.

You can buy an inverter DC 200 welding machine online and you will have no problem with a home electricity meter. The 100 current you said refers to the 2nd term, and the model I gave you is 200 current, which is also the 2nd termination, no problem. I'm a professional.

Isn't a household electric welder a household one? The output current is 100A, the voltage should be 36V, so the power is 3600W, the working current of 220V for the home circuit should be less than 20A, 4 and 6 square are available, don't worry about using 6 square directly, I don't know if it's right?

Wire from the distribution box alone, 10 square millimeters of wire is sufficient.

You can't pick up the wrong one.

Once the zero live wire is reversed, the switch controls the zero line, and the ** line cannot be broken. In addition, the outer metal housing is also prone to electrical conductivity. Therefore, the reverse connection of the socket will cause the electrical switch to be disconnected, and the electrical appliance is still charged inside, so the live wire and the neutral wire cannot be reversed.

The zero fire line of the lighting is reversed, and when the bulb is turned off, the silver flashes non-stop, and the bulb is easy to hold after a long time, which is very annoying. This is all because the switch is connected to the zero lift blind wiring and does not control the live wire.

Like the socket on the wall, if the live wire and the neutral wire are reversed, even if the small switch on the wall is turned off, the socket is still in a live state, which means that if the naughty children at home use a conductive object to buckle the wall, it will cause an electric shock, which is very dangerous! If the circuit breaker is reversed, it will cause the order of the zero live wire in the whole room to be reversed, and then the above situation will happen.

It's dangerous, and you can't take it wrong.

It should be in accordance with the principle of "left, zero, right, fire". That is, the plug (hole) on the left side is the neutral wire, and the plug (hole) on the right side is the live wire.

Experienced people may find that if the original wiring method of these two wires is interchanged, it will not affect the use. In fact, most electrical appliances can also be connected in this way, but there are certain dangers in doing so.

For some two-pin plug appliances, the zero live wire of the reverse socket will not affect it at all. Because the electrical appliances with two-pin plugs are generally plastic shells, and there is no need to distinguish between zero live wires inside.

But the triangular plug is different. First of all, the electrical appliances with the triangle plug are mostly metal shells. The switch of electrical appliances generally only controls the live wire.

If the zero live wire of the plug is in the wrong position, the switch of the appliance cannot be broken. This will cause the voltage to remain inside the appliance when it is not working.

And once the metal shell leaks, it will hurt people.

The air opening at home has not tripped, and you can check whether the watt-hour meter is still a leakage protector or insurance between the air opening. Connect a desk lamp directly under the watt-hour meter to see if there is electricity.

The line is easy to burn out, and it is generally easy to break where the wire has a joint, so you can know it by measuring it with a meter.

BAI will not.

Home line connection.

du wire, there will be no electric dao voltage on the side of the electrical appliance, and it will not be damaged. If the switch does not trip after the connection is generated, it means that there is a problem with the switch, there is no protection function, and the switch should be repaired and replaced.

Precautions for wire connection;

1. Generally used for sockets, it is a single-core square wire, a single-core wire with more than 3 horsepower air conditioners, a single-core wire with 6 square wires for the total incoming wire, and a two-color wire for the grounding wire.

2. Three rolls of different colors are used for a group of three rolls (with zero wire, live wire, ground wire) for lighting of lamps and lanterns, and two rolls of different colors are used as a group (for neutral wire and live wire).

3. The two-core and three-core sheath lines are used as open wires, which are mostly used for construction on the construction site, and are not used for home decoration.

4. The thicker the audio line, the better, it is recommended to choose 2 * 2 or 2 * specifications 5 The more the TV distributor is divided, the worse the TV signal, it is recommended to use 6 distribution as much as possible.

No, it won't. If the wiring at home is connected, there will be no voltage on the side of the electrical appliances and will not be damaged. If the switch in your home does not trip after the connection occurs, it means that there is a problem with the switch and there is no protection function, and the switch needs to be repaired and replaced.

Electrical short circuits also do not cause other electrical burns. When a short circuit occurs, one air switch will jump to another instantaneous short circuit, the voltage drops, and there is no electricity for other appliances.

Does the connection mean a short circuit? The first thing you should burn is your home's fuse, air switch or something.

If the wires at home are not well connected or contacted, it may lead to electrical short-circuits, overloads, leakage and other problems, and filial piety may damage electrical appliances or cause safety accidents such as disasters. Therefore, it is very important to install and connect the wires correctly. If you find that the electrical wiring connection in your home is poor or there is a problem, it is recommended to contact a professional electrician for inspection and repair in time.

When using electrical appliances, you also need to pay attention to some safety matters, such as not overloading electrical appliances, not using electrical appliances in a humid environment, and not forcibly using electrical appliances when they fail, etc. In short, proper use and maintenance of electrical appliances, as well as proper installation and connection of electrical wiring, can effectively avoid the occurrence of electrical damage and safety accidents.

Summary. Hello dear, it's an honor to help you answer <>

Dear, you've been waiting for a long time, no. The wiring at home will not have voltage on the side of the electrical appliances and will not be damaged, provided that there is a protection switch.

If the wires in your home are connected, will the appliances burn out?

Hello, I'm honored to help you answer <>

Dear, you've been waiting for a long time, no. Home wiring wiring, electrical appliances that and judgment side will have no voltage, will not be damaged, before the Huai and mention is to have a protective switch.

Hello dear, I would like to expand on this: if the electrical wiring in your home is connected (scientific name short circuit), the current will increase sharply, which may cause the circuit to be overloaded, damage the electrical appliances from the combustion base or cause fire and other dangers. Generally, when the wire is short-circuited, the fuse or circuit breaker in the circuit should automatically trip and cut off the power supply to protect the electrical appliances and home safety.

At this time, you need to check whether there is a problem with the wire connection and fix it in time to avoid similar problems. If the wire is short-circuited and does not trigger the fuse or circuit breaker trip, it may be due to damage or malfunction of the fuse or circuit breaker macro. In this case, the appliance itself may be damaged.

Dear, hello, according to my experience, in daily life, now basically equipped with air protectors, so generally will not damage electrical appliances. However, you should still check the safety of the home circuit regularly, and maintain and repair it in time to ensure the normal operation of the wires and electrical appliances to avoid secondary damage and potential safety hazards of electrical appliances. If necessary, please contact a professional for maintenance and treatment.

Hope mine can help you, dear <>

Hello Kiss now answers this question for you. Dear, if the electrical connection at home is not in the correct way, the engine bandwidth will be affected, so the possibility of burning out the electrical appliances is high. It is very important to connect the wires correctly, and since the load resistance of the line and the appliance are different, the specific wire should be used according to the connection requirements of the appliance.

Wires can be divided into two types: natural insulated wires and sheathed wires. The color of the outer sheath of the sheath is mainly divided into gray, black, yellow, red and green, of which gray is usually neutral wire, black is the live wire, yellow red is the AC signal line, yellow-red is the three-phase AC live wire, and green protection line. In addition, when installing electrical appliances and electrical home decoration, you should also choose wires with a high degree of matching to ensure the safe and stable operation of electrical appliances and home decoration.
