Frequent tripping of rural lighting electrical ready boards is a common problem, which may be caused by overload, short circuit, leakage, or equipment aging. The following 5 troubleshooting methods can quickly locate faults and avoid blind repairs.

1. Confirm the type of trip

Leakage protection tripping: The reset button pops up (needs to be pressed before closing), usually caused by leakage.

Air switch tripping: Without a reset button, direct closing fails, possibly due to overload or short circuit.

Differentiation method: Observe the switch status after tripping, and prioritize identifying the corresponding type.

2. Check if the load is overloaded

Phenomenon: When multiple appliances are used simultaneously (such as electric heaters and high-power light bulbs), they trip.

Troubleshooting: Calculate whether the total power (watts) exceeds the rated value of the switch (e.g. the maximum load of C16 switch is about 3520W).

Solution: Reduce the simultaneous use of high-power appliances or replace switches with higher rated currents (matching the current carrying capacity of the circuit).

3. Check for short circuit faults

Phenomenon: Immediately trip upon closing, possibly accompanied by sparks or burning smell.

Troubleshooting:

Turn off all electrical appliances and test them one by one. If they still trip, the circuit will be short circuited.

Check if the socket and bulb interface are loose or if the metal is exposed.

Solution: Repair the short circuit point (such as replacing damaged wires, fastening interfaces).

4. Detecting potential electrical leakage hazards

Phenomenon: The leakage switch frequently trips, especially in rainy or humid environments.

Troubleshooting:

Use a leakage tester to test the insulation resistance of the circuit (should be ≥ 0.5M Ω).

Check if the electrical plugs and wires are soaked or aged.

Solution: Replace damaged wires, insulation layers, or install moisture-proof boxes.

5. Investigate equipment aging issues

Phenomenon: electrical ready boards that have not been maintained for a long time are prone to tripping due to poor contact.

Troubleshooting:

Check if the switch contacts are blackened or burnt.

Test whether the grounding wire is effective (grounding resistance ≤ 4 Ω).

Solution: Replace the aging switch, tighten the wiring terminals, and ensure reliable grounding.

Summary: Prioritize troubleshooting in the order of "leakage → overload → short circuit → aging", with a focus on inspecting damp areas and recently added electrical appliances. If the problem is complex, it is recommended to contact a professional electrician to avoid the risk of electric shock.
