How to detect the safety performance of household electrical wires and cables
2024-05-20

The safety of household electricity relies on regular inspections of the condition of wires and cables. Users can check the appearance of the wires to see if there is any aging, cracking, or heating. For concealed wiring, professionals can use an insulation resistance tester to check whether the insulation performance of the wires is good. If significant voltage fluctuations or frequent tripping of electrical devices are observed, it may indicate a problem with the wires. Additionally, when replacing or adding high-power devices, it is necessary to assess whether the existing wires can handle the additional current load and replace the wires in a timely manner if necessary.
