Electrical Safety Tips
Touching electricity with wet hands is more than 10 times more dangerous than with dry hands.Induced voltage and ghost voltage can also light up a test screwdriver; always verify with a multimeter.If the live and neutral wires are reversed in a screw-type lamp holder, the metal shell will become live — extremely dangerous.When disconnecting, cut off the live wire first; when wiring, connect the neutral first to avoid forming a circuit that could burn your hand.Connecting aluminum wire directly to copper wire can easily produce sparks because the materials are different.When measuring voltage with a multimeter, start from the highest range and then step down to avoid damaging the meter.In a distribution box, there are two components you should not touch:[*]Power factor correction capacitor
[*]Current transformer
Wear a safety harness when working at height, and wear insulated shoes when working on the ground.
