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.

Electric fences are not connected to the ground in the circuit?

A short answer:An electric fence is connected to the ground only when an animal or a human being touches it to complete a circuit from the fence to the ground.A longer answer:The wires of an electric fence are not connected directly to the ground because, if that was done, the fence would be shorted out and would not be able to do its job!This is how an electric fence is actually hooked-up: the electric fence is connected to one side of a specially designed high voltage source and the return side of that source is connected to the ground.Then, whenever the skin of any animal - or human - touches the wire whilst standing on the ground in bare feet, they get a high-voltage (10,000) DC electric pulse from the electric fence. The shocks are designed to be only enough to make them jump back from the fence, not to "electrocute" them so badly as to cause serious injury or death.


Can a better ground lower electric bill '?

No, the only way that the electric bill can be reduced is to reduce the amount of electrical energy used.

No way


Why can some birds land on high voltage lines without getting shocked and and some can't?

To get electric shock, the circuit must be completed and the subject who is in the path, or who becomes the path gets shock. When a bird sits on the wire, there is no closed path or circuit hence it does not shock. Same bird while sitting on the wire, and part of its body touches the earth or ground it then will get shock.


Can one convert a two prong outlet to a three prong outlet?

Yes, provided that you have a ground wire in the box and that the ground wire is properly connected in the electric panel.

A tornado often appears dark were it is touching the ground be cause the powerful winds of the tornado lift dirt from the ground.


Why does a cow that touches an electric fence experience a mild shock?

When the cow comes into contact with the fence, it becomes an electric ground which sends an electric current into the cow, through the cow, and into the ground. The pain experienced from the shock is due to the current that flows through the cow.

Why do some electric panel have ground and neutral bonded together?

By National Electric Code only the Main Panel should bond ground and neutral. If subpanels have ground and neutral bonded, it could cause ground loops and shock hazards.


Where are neutral and ground wires usually bonded together?

Only in the main electric panel.

Are you down in football when your butt touches the ground?

yes if his hand touches the ground he is down but only if he is touched by contact and then touches the groundNo. A player is down only when a part of his body other than a hand or a foot touches the ground, or when the officials rule that his forward progress has been stopped.
