When analyzing common faults of split meter ready boards, you need to pay attention to the following aspects:

Circuit breaker status check: Check whether the circuit breaker is closed and make sure it has not tripped. If it triggers, there may be an overload or short circuit in the circuit.

Meter reading check: Check the meter reading to make sure it matches normal usage. Abnormal meter readings may indicate a faulty meter or current leakage.

Wiring connection check: Check the cables and connections inside the split meter ready board to make sure they are not loose or disconnected. Loose connections can cause increased resistance and heating.

Hot Spot Detection: Use a thermal imaging camera to inspect the interior of an electrical box for unusual hot spots, which may be a sign of poor wire connections or faulty electrical components.

Resistance measurement: Use a multimeter to measure the resistance at key locations within the electrical box to check for abnormal values, which will help find where the resistance is elevated.

Current measurement: Measure the current to ensure it is within the normal range. Excessively high current may indicate an overload or malfunction.

Insulation resistance testing: Conduct insulation resistance testing on cables and equipment to ensure good insulation performance.

Through comprehensive analysis of the above steps, the fault of the split meter ready board can be initially located and corresponding repair measures can be taken. If the problem cannot be solved, it is recommended to call a professional electrician for a more in-depth inspection and repair.
