What to Do If a Container House Has Electric Leakage

If electric leakage occurs in a container house, immediately stop using the relevant electrical appliances and systematically resolve the issue by following the steps of detection, handling, and prevention.

1. Detect Electric Leakage

1. Use a Digital Multimeter: Measure the voltage and current between electrical appliances to determine if there are any abnormalities. If the voltage or current exceeds the normal range, electric leakage may be present.
2. Utilize a Residual Current Circuit Breaker (RCCB): An RCCB can continuously monitor the leakage current and immediately cut off the power supply if an abnormality is detected, preventing the risk of electric shock. If the RCCB trips frequently, focus on identifying the location of the electric leakage.

2. Handle Electric Leakage

1. Sectional Troubleshooting Method:
   • Unplug all sockets, disconnect all loads, and attempt to close the circuit breaker. If successful, the electric leakage originates from the electrical appliances or wiring; if unsuccessful, it may be due to a fault in the main circuit or distribution box.
   • Open each socket one by one and check for short circuits or loose connections at the joints. If a particular socket causes the circuit breaker to trip, further inspect the wiring in that section.
   • Use two long wires to directly connect from the circuit breaker to each section of the wiring, and test by closing the circuit breaker section by section. Once the faulty section is located, continue to subdivide and troubleshoot until the specific point of electric leakage is found.
2. Repair Circuit Faults:
   • Conduct a comprehensive inspection of the internal electrical equipment in the container house, focusing on issues such as aging wiring, damaged insulation, and loose connections. Promptly repair or replace damaged components.
   • If severe equipment aging is found (e.g., cracked wire insulation, burnt sockets), replace them immediately to prevent electric leakage caused by overloading.
3. Strengthen Grounding Measures: Ensure that all electrical appliances are properly grounded, with the grounding wires securely connected and free from rust, reducing the risk of electric shock in case of electric leakage.

3. Prevent Electric Leakage

1. Choose High-Quality Electrical Appliances: Purchase electrical products that comply with national standards and avoid using inferior or unbranded devices to reduce the risk of electric leakage from the source.
2. Regular Maintenance:
   • Check the insulation performance of wires, plugs, and sockets monthly, and replace any damaged or aged components immediately.
   • Conduct a comprehensive inspection of the wiring in the container house every six months, paying special attention to the aging of wiring in older houses.
3. Standardize Circuit Design: Electrical facilities should be planned by professionals to avoid overloading or chaotic wiring layouts. For example, high-power electrical appliances should have separate wiring and avoid sharing circuits with other devices.
4. Promptly Address Hidden Dangers: If power sockets are exposed, damaged, or if the wiring is heating up, immediately stop using them and have them repaired. Do not operate them in a faulty condition.
5. Seek Professional Help: If you do not possess electrical repair skills, contact professional technicians for inspection and repair. Do not attempt to operate on your own, which may lead to the expansion of the accident.
