Question

prevention of electric shock 13 points

Answer 1

1.Turn Off the Power.


2.Test for Power

Always test for power at the device or equipment after turning off the circuit breaker. 
3.Beware of Capacitors

Capacitors are like batteries in that they hold an electric charge on their own. They are often found in appliances and equipment that use motors, such as air conditioners, refrigerators, freezers and garage door openers, as well microwave.

4.Protect Yourself With GFCIs

If you're doing work that uses electricity -- that is, with the power on -- plug your extension cord, tool or other equipment into a GFCI (ground-fault ​circuit interrupter) outlet, or use a GFCI-protected extension cord. GFCIs detect electrical faults and shut off the power to prevent shock. Faults can be caused by things like water getting on cord contacts or by shorts inside tools, cords or appliances.
5.Use Insulated Tools

It always makes sense to use insulated tools for electrical work.
6.Never Connect or Disconnect Under Load

When an appliance or other device is wired or plugged into a circuit and is running, the circuit is "under load." That means the device is drawing power and electricity is flowing from the circuit into the appliance and back onto the circuit wiring in a continuous loop.
