6 reasons why our sockets and vending machines are on fire

Did you know that it is enough to eliminate only 6 common problems (arising mainly on your own carelessness) and such a problem as a burnt out socket or an automatic machine will not touch everything for a very long time. If you didn't know, then this article is definitely for you.

6. Bad contact

Electrical engineering is the science of contacts. Where contact becomes insufficient, problems arise: voltage drop, excessive heating, arcing, etc. Therefore, so that this does not happen, it is necessary to de-energize the home once every few years and tighten the latching contacts on sockets, switches, circuit breakers and other switching devices. Of the tools, only a curly screwdriver is required.

5. Old appliances

In order for the wiring, machines and sockets to work properly, they must be replaced in time. For example, today in apartments and private houses there should be no "traffic jams", Soviet switches and knife switches of the same era. Is that so? If not, then it is time for large-scale changes.

4. Intervention of "pets"

Namely - rodents. Mice and rats are a real problem, which is quite problematic to solve. So that there are no traces of the activity of these small mammals on the wiring, it is necessary:

  • If possible, lay the wiring in metal sleeves or in the wall by strobing.
  • Install the switchboard into a recess in the wall, and then putty. Choose a cabinet that is as tight as possible.
  • At the first sign of rodents, use special chemicals.

A bitten core of the wire going to the outlet will cause strong heating of the latter, and possibly a fire.

3. Lack of NShVI

NSHVI - sleeve-type lugs, special attachments for conductive conductors. It is necessary to install them then in order to make the most even and correct area for contact.

It is enough to remove the insulation from the wire, put it on the NShVI core and crimp it with a crimper. After these simple steps, the tip can be clamped in the machine. In its absence, the contact between the wire and the fixing clip will not be reliable enough, which can cause a fire in the future.

2. Incorrect wiring

And with incorrect laying, the wires suffer from mechanical damage, such as chafing or an unsuccessfully twisted self-tapping screw - a fairly common problem. To avoid this, all wiring should be laid either in corrugation or in grooves, you can also use a metal sleeve, and in the most extreme case, a cable channel.

1. Too many consumers

It should always be remembered that even a high-quality wire with a cross section of 2.5 mm2 is not able to withstand more than what is prescribed for it by the laws of physics. If the hob is connected to the socket, which is mounted on such a cable, then the fire is guaranteed!

You need to know where and what lines are laid in the home and use them exclusively for their intended purpose. And not to think that a short-term increase in power will definitely not lead to something terrible - it will give you a ride.
