What causes an electric motor body to give an electric shock when a person touches it and the ground together?
That condition is called a "ground fault". That's when the insulation of the motor winding has a break somewhere, allowing current to leak to the motor housing. The motor SHOULD be grounded, protecting the user from electrical shock, but many older motors were not grounded, providing the potential for just this type of condition. Newer motors are often "double insulated", meaning that not only is the motor winding insulated, the motor housing is also insulated. Often the housing of a double insulated motor is made of a type of plastic.
Is there a symbol to identify a double insulated power tool?

How one can insert a 2 terminal plug in a three pin socket?

What are the function of double insulated case?
An electrical appliance which is double insulated does not have an earth wire fitted. The appliance is designed in such a way that the electrical parts can never come into contact with the outer casing of the device. Common double insulated appliances are hair dryers, radios and cassette players.
Why can you use electrical devices without getting shocked?
To receive a shock from electrical devices you have to become part of the electrical circuit. Most electrical devices come in two categories. One, the device is grounded and the other is the device is double insulated.The grounded devices have their metallic frames grounded. On a short circuit fault this will trip the breaker and isolate the device's fault before you have a chance to ground out the device by touching it.The double insulated device has two covers that protect the user from shock. The double insulation type of protection is usually used on hand held power tools.
In baseball what does giop mean?

Why are hair dryers not earthed?
Things that aren't grounded, like hair dryers, are double insulated. If the hair dryer gets a short circuit, the two layers of insulation will protect you. Hair dryers also have a ground-fault circuit interrupter plug that protects you if you drop the appliance in water.
Why wont birds die on a wire?
