Why does the light in two rooms not work?
Good afternoon. I installed a shield in the apartment. The connection diagram is as follows - on the floor in the UZO switchboard, from it wires to the meter, from the meter to the machine 16A, from it the wires go to the apartment in the shield (which I installed). In it, on the RCD from him to 6 machines for 16A (one machine for each room). When testing, I found that electricity is only in two rooms. In the others, it seems, too, there is (a tester shows), but apparently low-current. LED lamps shine somewhere hardly, somewhere do not shine at all. What is the reason for this fact? Maybe the entry of the wire into the apartment did not have to be taken from the machine with the switchboard on the floor?
Hello! First of all, check whether the wires in the terminal blocks of the automatic machines are well stretched. Next, check the quality of the connections in the junction boxes. If everything is normal - maybe somewhere during installation the cable is broken, as if there is a contact, but the line resistance is large. This can be checked if you turn off the voltage, close the phase with zero at inoperative points and measure the resistance between the phase (from the machine that supplies these points) and zero.
