What are the three common faults in lighting circuits?
Release Time:

The common faults in lighting circuits mainly include open circuits, short circuits, and leakage currents. These faults can lead to lamps failing to function properly, circuit breakers tripping unexpectedly, or posing potential safety hazards.

Fault Types and Characteristics
Circuit Break: A break occurs somewhere in the circuit (e.g., a filament burns out or a wire has poor contact), preventing current from flowing. This results in lights failing to illuminate or specific circuits becoming inoperative.
Short circuit: Direct contact between the live wire and the neutral wire causes a dramatic surge in current, triggering the fuse to blow or the circuit breaker to trip, potentially leading to damage of the wiring.
Electrical Leakage: Damage to wire or equipment insulation causes current to leak into non-energized components, potentially posing an electric shock hazard or leading to energy waste. This issue is often accompanied by a decrease in insulation resistance.
Other relevant instructions
Overload or poor contact may occur, but they are not listed as the three core faults.
During maintenance, use a voltage tester or multimeter to locate the fault point. Prioritize addressing short circuits and leakage currents to prevent safety hazards.
