Wiring differential machine

single phase 220 V

in apartments and private homes, often using an outdated version of the wiring - one phase.In this case, the rated voltage is 220 V, so you must use a two-pole product.As regards wiring diagrams Emergency circuit breakers, it can be presented in two versions.The first - when the protection is set only after the electricity, serving the whole house wiring.

In this case, when triggered and automatic cut-out will be harder to find a way out the cause of the failure, it is desirable to give preference to the second, more reliable option.

correct wiring diagram Emergency circuit breakers in a single-phase network:

As you can see, for each group of wires mounted on a separate article.Emergency circuit breakers If one works, the other will continue to function.

three-phase network of 380

The only important difference between the 3-phase network lies in the fact that instead of one phase conductor on the input provided at once three phases: L1, L2, L3.In this case, you must use a 4-pole Emergency circuit breakers on 380V, wiring diagram which will look like this:

This option can be used in a new house, or rather cottage, which must withstand high current load on the electrical equipment.Also, this option is sometimes used when installing wiring in the garage, becausehere can be applied strong welding machines, compressors and other electrical equipment.

Without grounding

All previous schemes differential machine connections were with the ground, now I would like to provide an outdated model, which uses a two-wire 220V network.

Connect Emergency circuit breakers without land should be as follows:

This method of wiring can be seen in old houses panel type.It is extremely safe and, therefore, recommend that you replace the wiring in the building to the new, with grounding.

Worth also view existing connectivity options in the form of reviews:

That's all that I wanted to talk about this topic.We advise you to use differential machines only on the popular manufacturers: abb, legrand (LeGrand), IEK and Schneider electric, that protection lasts for a long time, and most importantly - on the conscience.
