When an Electrician Gets Dangerous: 8 Irregularities to Remediate!

  • Dec 14, 2020

Electrical products surround us all the time: they are switches, sockets, LED and ordinary lamps. What can I say, even if the car has both low and... high voltage. And the current strength is not always beneficial, if you do not follow simple rules, the electrician turns into a direct threat to both health and human life.

1. Never use tees

You should not use a tee at all, even in critical situations when the outlet is needed as a breath of fresh air. Any tee - this is several additional consumers, respectively, a high consumption of power consumption. And the consequence can be a burnt wire in the wall, which will take a lot of time to replace.

2. Pull out the plug only by holding the socket

An important note, since many users, when disconnecting an electrical appliance, simply pull the cord out of the outlet and do it very aggressively. After such treatment, the socket may not only fall out of the hole in the wall, but also pull out the wires connected to it. Hence the possibility of a short circuit.

3. Finished wiring - make a plan

A diagram or drawing of electrical wiring in an apartment is:

  • Less troublesome troubleshooting.
  • Savings on future upgrades or wiring rework if required.

Therefore, it is better to spend a few hours, but significantly simplify life in the future.

4. Do not lay wires in flammable corrugated pipes

For many amateurs in the world of electrics, it is enough to lay a wire in a corrugation and this will mean the highest degree of safety. Unfortunately, everything is not so simple, and many varieties of modern corrugated pipes are quite good, and most importantly, they burn out quickly.

5. Do not lay the self-supporting insulated wire indoors

Self-supporting insulated wire is intended for outdoor use, its use indoors is unsafe. Especially when polyethylene pipes are used for its additional insulation.

6. Do not run unprotected wires behind wooden surfaces

Many owners of private houses use lining for decoration - a very beautiful and practical material that is obtained from recycled materials after the production of wooden products. If you lay an unprotected high-quality corrugated wire behind the clapboard, then with a short circuit, everything can end in a serious fire.

7. What does the choice of wires of small cross-section lead to?

To prolonged heating, damage to insulation, contact with bare cores and... short circuit. When laying electrical wiring, you should always be guided by the golden rule: light - 1.5 mm2, sockets - 2.5 mm2, electric oven - 4 mm2. This section has been calculated and tested by generations of electricians.

8. Do not leave the wire dangerously close to a heat source

Additional external heating only contributes to damage to the insulation, so it is best not to leave wires near radiators, boilers or portable convectors, but on the contrary, move them away or hide in corrugated pipes.
