Low voltage at half of the outlets in the apartment
Good afternoon! Apartment Khrushchev. At half of the sockets, the voltage dropped to 40 Volts (measured with a multimeter). The rest shows stable 220-222 volts. Light is on in all rooms and the kitchen. What could be the reason?
Hello! Did you measure no load on this line? Most likely with a load. Look for bad contact. It can be both in the machine feeding the group, and in the distribution boxes or in other places where the wire is connected along the line. There can be no more reason.
