Common faults in split meter ready boards include:

Inaccurate meter readings: It may be a problem with the meter itself, or it may be caused by a faulty current transformer or voltage transformer.

The meter has no display: The meter itself may be faulty, the power supply may be faulty, or the connecting circuit may be faulty.

Leakage protector tripping: It may be caused by fault of the leakage protector itself, excessive leakage current, or leakage in the line.

Short circuit inside the split meter ready board: It may be that the circuit is in poor contact or the insulation is damaged, causing a short circuit in the current.

Temperature is too high: It may be that the electrical equipment is overloaded, ventilation is poor, or the wires and cables are overheated.

Poor wire contact: Sockets, switches, etc. are not firmly connected, and poor wire contact leads to equipment failure.

External damage to the split meter ready board: If the box is damaged and the seal is not tight, external moisture and dust may enter, affecting the operation of the equipment.

Detecting and resolving these faults requires professional electrician skills and equipment to ensure the proper operation and safety of the split meter ready board.
