Why does a 63A machine knock out at the input?
Hello. I have such a problem. Knocks out a double in a water machine at 63A 220v. He stands immediately after the counter. The meter stands on the street in the same box with the AB. An electric boiler of 9 kW is connected to it (each heater is 3 kW).
The cable from AB to the boiler with section 6 is copper, rigid, Gostovsky. For 4 months everything worked properly, the cable was slightly warmed up. But now, the second day, every 63-30 minutes AB 63a is triggered, sometimes time can be longer, sometimes 5 minutes. When disabling any ten, everything works. Could this be a problem in AB or a reason in another? Please, help. It is cold here. Thanks in advance

Hello! Try disconnecting the wires from the AV - if the wires are burnt or oxidized, strip them, strip the terminal block of the AB and stretch everything again. There may be a reason for this. Is an RCD installed? It may be such that in the boiler the heating elements began to “cut” into the housing and the current increased, therefore it can also knock out. But I am inclined to the fact that this machine needs to be replaced.
