Outdoor leakage protector is broken, regardless of property management.

I don't think the property can be maintained free of charge, because it is the owner's own property, and the owner has no obligation to maintain the property for the owner free of charge. The fault handling method of leakage switch is 1. The maintenance team of the engineering department is responsible for handling, and the maintenance man will arrive at the site for handling 15 minutes after receiving the maintenance order. 2. There are three reasons for the tripping of the leakage switch: poor connection of the connector, poor contact, heating and burning of the contact, load tripping caused by short circuit or leakage, and failure of the leakage switch itself. 3. Before installing the leakage switch, check whether the insulation of the controlled circuit and electrical equipment is good, and the insulation resistance should be greater than 0.5 megohm before sending. 4. For the newly installed leakage switch, use the test button to check whether the leakage protection performance is normal under the charged state, and then check it every 1 ~ 3 months. 5. After the earth leakage switch is installed, the original protective grounding or zero connection cannot be removed. Check whether the grounding and zero connection device is reliable every 3 ~ 6 months. 6. After the leakage switch trips, find out the reason in time and close it after troubleshooting. 7. If the leakage switch trips due to the short circuit of the controlled circuit, the cover must be opened to check the contact, and when the contact is seriously damaged, it should be repaired or updated.
