There are mainly three reasons for the misconnection of electricity meters: 1. The meter box manufacturer makes mistakes in the wiring of the meter box; Wrong line, 3. The developer leads to faltering connection when laying out the household line. At present, in the process of troubleshooting and correcting the problem of meter stringing, the investigators generally use the following two methods: 1. Pull off the main switch of the user from house to house to observe whether there is a change in the current of the electric energy meter; this method affects the normal operation of the customer. Electricity consumption; 2. Use current clamps to measure the lower wire of the air-opening, and at the same time increase the load on the user side to observe whether there is a change in current; this method continuously consumes electricity from the user. When checking, the customer uses electricity normally, but increases the user's electricity bill. Cause customer dissatisfaction and unnecessary disputes.
