Power overrun due to incorrect meter connection
Electricity consumption increased from 100-110 kW to 160-180 kW. The counter is working. Electricians from the house management set up a backup counter next to mine on the site. She asked to put a backup in the apartment, they refused, although she was sure of the work of the counter. There are doubts about the connection scheme, which I declare. But she didn’t notice that the electrician checked it. From the very beginning they nodded towards the wiring in the apartment. What to do? How to force them to check the circuit. Moreover, the switch in the shield burned out, there were problems, so to speak.
Hello! Your argument about the scheme is not clear. If no changes were made to the wiring, then why did the circuit become incorrect? The machine has failed or from elementary wear or perhaps your load has really increased, maybe it's really in the wiring. This can be calculated by checking the wiring with a megger and ticks to measure the real current.
