Why is the difavtomat triggered when the refrigerator is connected?
Throughout the apartment spent a new wiring in cable channels. Installed a new switchboard in the apartment. The wiring was divided into groups into separate machines. Entrance from the switchgear of the entrance with the installation of a differential machine 30mA.
QUESTION: when voltage is applied without the refrigerator turned on - everything is fine, it is worthwhile to turn on the refrigerator; the difavtomat turns off. Tell me what is the reason for turning off the difavtomat, if the refrigerator is new?

The new refrigerator is unlikely to be short, the DIF should be increased. What is the nominal value of your difavtomat? Still, a large group may have turned up in the protection zone of a differential automaton, they do not like large groups, especially if there are receivers with pulse currents. And 30 mA at the input is too sensitive.
