Is it necessary to use the test pen after a power outage?
Thread Content
When repairing electrical equipment, we usually cut off the power supply and use electrical wiring and other procedures. In order to ensure that the power supply is completely isolated and avoid leakage of electricity that may cause industrial safety incidents, my boss recently required electrical personnel to use a "test pen". Is it necessary? Is there a national standard?* * Are there actual results of implementation?? This post was last edited by hw197358 on 2009-4-7 14:01 ]
It's necessary as a precaution. I don't know whether it's high voltage or low voltage. If it's low voltage, don't your electricians have a test pen? For high voltage, if you don’t have a test pen, I don’t know how your high-end equipment is designed and accepted. The boss personally suggested it. He really pays attention to safety.
