if there were only 3 machines it would be easy, now I will send a photo
it’s very three-phase with 25 amperes
without differential circuit breaker
nice work but dangerous
I don’t know if you have any safety standards
I see that you have put in 4 Divisional circuit breaker
you have one that is closed
A circuit breaker only serves to protect an electrical circuit and the receiving devices connected to it. It does not detect current differences caused by a leakage current and therefore does not protect people against the risk of electrification 
note the 3 automatic leakage current detection. they operate at 30mA
once again I did not install THIS my task was to determine which wire is responsible for what, turn off the necessary
me machine guns
from the city network. now the section I need is powered through a hybrid inverter, which automatically switches to a backup power source in the event of a power outage
The 5kw hybrid inverters are very good.
Be careful, it has to be separated from the city current.
otherwise it will fail due to overloading
the risk is that the installation is too old to be used.
hybrid inverters are 2.5" diameter cables
I have seen that you need a 2.5" diameter cable for this.
At home, we only have 1.5" diameter cables.
thanks for the warning, just a small clarification we have a 3 kW inverter.
it is connected by wires 2.5.
I think you will be in a slight shock when you find out that on one line there was a total load of 5 kW. some smart guy hung a washing machine and part of the sockets in the house on one machine boiler …
Парни а вы точно не электрики ?
5 kw is 30 amperes good
it has good power
3 kW 13 amps is the rated power of the inverter

Subscribed power in kVA or kW
3kW 3,000 watts
this is 15 amperes not 13 amperes

You should see the condition of the wiring on the inside and outside of houses and the streets in Spain, you would s__t yourself. 
Euro wiring doesn’t even have earthing. 
it’s not true you have in europe norne
here they are informing you
All installed equipment must have a mark of conformity such as
CEBEC
VGS
VDE
KEMA
Well all electrical sockets are only 2 pin so no earth there.
Standard sockets in Spain are 220V. In older buildings, 110V sockets or a combination of both are still used. The sockets used in Spain are two-pin sockets. They can be either small, which is suitable for small sockets, or large, which requires the use of an earthing strip
