Will replacing a machine help if household appliances burn out?
Hello. Maybe tell me. For the second time in the past two years, the hob burns, air conditioning, kettle. The var.surface is connected to 3 phases, the machine stood at 40 A. Three air conditioners are connected through a 16-amp 3-phase machine, one constantly works. At the entrance, a 50 A. difavtomat. The master who made the stove said to replace 40 A with 16A. Would all this burn out again?
Zero does not hurt to check, when it burns out, just household appliances fail. It is also necessary to install a pH (voltage relay). With so much technology, it will not be out of place.
Thank you. Is it possible to use a relay instead of the introductory one in the apartment, taking into account the fact that there is a semiautomatic device in the stairwell?
Can. Note that the voltage relay does not protect against leakage and short circuit, it controls the voltage value. Therefore, they are put together with the RCD.
The differential machine.
