How to choose the switch?

Types of automatic devices

most common in the use of three types.This, as it is called, an ordinary car breaker tripping device (RCD acronym) and differential circuit breaker (differential. Automatic).

Residual current circuit breaker

device tripping current calls coming into the house or apartment with the return,.When the insulation is damaged and there is a loss of power, the RCD quickly disconnected.Differentiated machine performs both functions and the circuit breaker and the RCD.

Differentiated machine

Which machine to put in a house or apartment?

The first thing is to remember each before installing a circuit breaker on the counter is that automatic protects the supply line, and not the load on the devices.Its main task is to protect the cable against overload, overheating and fire outbreaks.Because make the right choice of parameters and denominations machine is so important.

First you need to decide what you will connect to this transmission line.Enter any current and no cables is also important, but this issue we are not concerned in this article.E

If this is the outlet for the dishwashing machine, it is one thing, but if it's an office or kitchen, where a lot of devices working at the same time, all powered by a single line, it is the other option for such needs the approximate amount of power consumed.Here to calculate this same power to get back to school days, where the power is referred to the P, calculated by multiplying the effect of electric current on the voltage.Denotes the strength of the current I, and voltage - U. And we find by calculations: I = P / U.You will wonder: why to know the strength of electric current (I)?In order to select the proper machine as they differ from the current intensity.Now mark the elementary consistency for the machine which puts:

  • Calculate with power;
  • Divide this power to 220v;
  • The store select your own, or to say how much power is needed for an automatic circuit breaker.

But it is worth remembering that the employee putting the machine if you do not own, must first check the place of attachment and guard itself, which is the counter.Entering the house, apartment or other premises lighting installation should begin with the machine, as it protects the outlets and other devices from overheating and other adverse factors.Put on the circuit breaker should be aware of the timing of its work, the conditions of the performance of this work, so is obliged to monitor his condition and state of the counter & Proofreading electric current.

Remember: there are electrical, moisture should be absent, or may suffer appliances and lighting in the apartment.
