Common mistakes electricians self-taught

I find it difficult to understand when a person is in something does not understand, but surely it does. In this case it is the work of an electrician. If some mistakes can be easily corrected without consequences, even if necessary to tinker, spending a lot of time, while others are fraught with fire, the loss of his property, and sometimes death. I told you the story about the most trivial mistakes that regularly make homegrown electricians.

When there is no scheme

Most handyman before laying the wiring diagram is never. And it does everything "by eye", in the course of carrying out calculations. After all, in the process it seems that you are sure to remember everything, and no disaster will happen. But the memory - a piece interesting, and it has a property to fade. And after 1-2 years, when you want to hang a mirror or to nail a shelf, you can get a drill directly into the wire. Murphy's law always works perfectly!

Therefore, wiring layout should always be on paper, and it should be stored. Plus it greatly facilitates the calculations, there will be no excess cable, and then did not have to think about how to make a few more outlets.

If it so happened that you bought a new apartment, the former owner has not given you the circuit, I recommend to buy a special detector for wiring search.

When the screw terminals are arranged in the wall

In some cases, the joints of electric wires required to "sew up" the wall, but do not show in the junction box. And homegrown electricians often make the mistake - they connect the wires screw klemmniikom and is strictly prohibited. Element require periodic tightening of the bolted connection, and if it is in the wall, how to do it? Nothing.

If we leave everything as is, then a few years later in the clip contact weakens, it begins to burn, as a result, the risk of fire increases significantly. It is for this reason, the screw terminals can be placed only in distribution boxes in which you can easily access.

Work under stress

This is a mistake, not only beginners, but sometimes professional electricians. Ironically, the latter even more often it is performed. Or rely on their professionalism, or simply too lazy to cut down traffic jams. One careless movement fraught electric shock.

Installing conventional switches and sockets in the room with high humidity levels

For experienced electricians frequently approached by people complaining that sockets designed for flow-through water heater or boiler, a spark. The reason is simple - simple installation sockets / switches that are designed exclusively for the premises with normal humidity.

Here it was included in the bathroom stiralka

If you install the outlet in a room with high humidity, such as in the bathroom, buy a variety of moisture proof, equipped with special protective shutter. Of course, they are twice as expensive, but also problems in the future will not be.

Errors when removing the insulation

Novice electrical removed from the multiwire conductor through the insulation of the knife circumference, as a result, the upper wire are cut thin, which reduces the cross-section conductor. And it's not correct. Remove always: spend a knife diagonally along the electric wire - as if you sharpened a pencil. From the first time it is unlikely to succeed without one core damage, but if you get the hand, the process will be faster.

No need to climb to where you do not understand - I adhere to this principle. What do you think about it, is it worth to save on electrical and do everything yourself?
