An electrician does not forgive mistakes, even if they are minor. If you have to replace the switch or socket yourself, you must first prepare for this. If you omit even a small error in actions, this can cause a breakdown of the entire system and a threat to your health.
Those who know practically nothing about an electrician always make typical mistakes:
- Twist copper and aluminum wires into one twist.
- The switch is used to open the wrong wire.
- Poor contact retention.
Beginners make a lot of such mistakes, and the consequences are very sad. This usually ends with a strong electric shock or fire.
To save newbies from significant mistakes, I decided to talk about the wires and switches that open them. For the Russian people, a lot happens at random - we have what happened. And if initially the problem did not manifest itself, this does not mean that everything was done correctly.
Where to install the switch
I absolutely do not pretend to be the author of further information, since everything was invented before me. Rules and regulations prescribe the installation sequence for the circuit breaker. But how often are these rules followed? Alas, not often.
The truth that everyone should remember: the breaker only opens the phase.
On any switch it is written how much ampere it can withstand.
The phase must be opened only with a switch. The supply of electricity is carried out through the phase wire, there is no voltage at zero.
When repairing a cartridge, in what order will you proceed? First of all, it is necessary to de-energize the cartridge. To de-energize the entire apartment, it is enough to turn off the machine. If the switch is correctly installed and the phase has been opened, it is safe to work with the chuck.
How you can not connect the switch
I believe that it will not be superfluous to remind once again that the switch is placed only on the phase wire through which the current flows. If you put it on a different wire, you will receive a dangerous electric shock on contact with the cartridge.
Even a simple replacement of a light bulb in this case will result in a good electrical "shake-up". If the insulation is broken, the chandelier will be under constant voltage, therefore, it should not be touched.
A person who accidentally touches energized equipment becomes a conductor for electricity. According to the regulations, the lighting groups do not need to be subjected to differential protection.
If the neutral wire is opened by the switch, the lamps glow dimly even in the off state. This can be easily verified with LEDs. I happened to face such a situation.
