Main causes heating cable wiring and electrical supply cord

Heating supply wires - is an extremely dangerous phenomenon that requires immediate removal. But before embarking on a repair, you need to understand where and why is heated. In this article we just look at the main causes of heat and how to resolve them. So, let's begin.

Why can bask in the cable or power cord

So let's start with the fact that will determine the main causes of heating. There are several main reasons, namely:

1.Kabel either the power cord can not handle the current load.

2. Wiring is formed with irregularities and due to this heating occurs.

3. Wire connections are made properly.

4. Poor quality of the supply cable or cord.

These are the main reasons for heating cable, now let's talk about them in detail, immediately examining remedies.

How to solve the problem

First, let's consider the case where the power cord of the appliance heats up.

So, first of all define the heating location:

- heated area near the supply plug.

- heated area outside of the appliance.

- heated or all of the supply cable.

So, in a first embodiment, the causes can be two: this is a bad contact wires inside the plug. And Remedy is: disassemble the fork and stretch bolt connection, if necessary.

A second reason may be the jack from intensive operation sponge loosely fixed plug sockets and because of this, in this location is heated. Remedy following: Ideally change the socket for quality with special biasing springs. But if you can not, simply by using pliers to squeeze the sponge contacts

Attention. Works with the socket can be carried out only after the machine is turned off, the supply line, and with a multimeter (indicator) will be checked by the absence of voltage.

Another embodiment of the heating outlet is not consistent with its nominal current flow. Perhaps you have designed for socket 10 AndAnd you connect to it powerful appliance. The solution here is only to replace the socket with a more powerful, designed for 16 And.

If you have a heated cord around the appliance, then the cause is too poor contact. In order to eliminate open the appliance housing and pull the bolt connection on the device.

But if you have all the power cord heats up, it means that the manufacturer saved negligent and instead, for example, wire size 1.5 mm2 set with a cross section 0.75mm2. In this case, help is only a complete replacement of the supply cord.

Now let's look at the causes of the heating wire itself

Let's start with the most banal and common cause. In many homes the old aluminum wiring and laying it looked forward to some load, and now the electrical load on the network have become disproportionately. And because of this wiring starts to overheat. In this case there is only one solution: a complete replacement of the wiring in the house (apartment).

It is also very common embodiment, when the wire is overheated in the distribution board. The reason for this lies in bad contact or incorrectly performed connection.

For example, if using a flexible cord, then plug it into the machine or on the ground bus without pre-crimping is strictly prohibited.

Remedy following: perform crimping flexible conductors and mandatory periodic broach all bolted connections.

As heating can occur in distribution boxes. The reason is the same - bad contact. To resolve this problem you must replace twist on a quality connection, such as a crimp sleeve.

Important. If the junction box are connected with aluminum, copper, such a compound can be performed only through special connecting terminals. As all the work in the distribution boxes and the panel must be made with a stress relieving.

Separately, an extension cords

I also want to talk separately about the extension (Surge Protector). Many are mistaken, if you can stick a load of the extension cord 4 outlets in each of them 16 Amps, So to each outlet of the extension can be connected load, calculated on

16/4 = 4 A.

And if you are using a drum-type extension cord, when you connect, for example, welding is required to completely unwind the wire from the drum. Since the state in irregularly wound wire inductance occurs, which further heats it, and it can lead to melting of the insulation.

conclusion

That's all I wanted to tell you about the causes and solutions for reducing the heating cable or power supply cord. If you like the article, then put his finger up. Thank you for your attention!
