An "electric leak" to ground from a hot wire should trip a breaker or fuse.
If you believe your neutral is going to ground before it reaches the panel, this may be hard to find. I would start by ensuring that your neutral connections or done correctly at each splice.
While doing this, check to ensure that you do not see any bare conductors on your neutral. This may be caused by mishandling or varmints (that would be mice and such). Also check to ensure that device screws (that would be screws used to mount switches, receptacles, and such) have not punctured your neutral. Damage like this can be hard to find because the damage may be so small that when the device is removed, the hole created by the screw may close itself and not be visible.

Can electricity leak from a house causing higher power bills?
No. An electrical leak is an electrical ground. When any line grounds out, the circuit breaker will trip and shut the power off. With the power off the watt meter stops recording so that there is no billing at that time.
How do you do earth testing?
One way of "Earth fault testing" is to use a High Pot device. This send a high voltage with a very low current through the equipment and will tell you when there is a leak to ground.
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.
What are advantages of gfci circuit breakers?
Advantage #1 - Shock Prevention The most obvious advantage of a GFCI outlet is that it prevents shocks and electrocution. A GFCI outlet has a built-in sensor that monitors the inflow and outflow of electricity from an appliance. For example, if a live wire inside an appliance is in contact with the metallic surface of the appliance, then, you will receive a shock if you touch this appliance. However, if the appliance is plugged into a GFCI outlet, then the GFCI will notice the change in electrical flow occurring as result of the loose wire, and it will immediately shut down the power. Thus, GFCI outlets are necessary for shock prevention. Although they are slightly more expensive than regular power outlets, this massive advantage makes them well worth the additional cost.Advantage #2 - Fire PreventionThe primary function of a GFCI outlet is to detect ground faults. Since ground faults, which occur when the flow of the electrical current leaves a circuit, can cause electrical fires, it is safe to say that one of the advantages of installing a GFCI outlet is the prevention of fires. Although electrical fuses do offer basic protection against electrical fires, when they are combined with a GFCI outlet, you never have to worry about an electrical fire harming your home or workplace.Advantage #3 - Prevention of Damage of Appliances Sometimes, over a period of time, as insulation breaks down, a certain amount of electric current begins to leak into household appliances or other electronic items. If the outer body of the equipment is not made of metal, you may not get a shock, but this constant leakage of current will damage the equipment. In fact, this leakage of electricity is one of the most common reasons why computer hard disk drives fail. With a GFCI outlet, you do not need to worry about this happening. This is because the instant the GFCI circuit detects a leak, it will shut down the circuit. This can help prevent expensive equipment and appliances from getting damaged due to electrical leaks.
How much electrical energy is required to cool 580 liters refrigerator capacity?
That doesn't depend only on the volume. It also depends on the quality of the insulation, and on the shape. If the insulation is very good, you can keep the refrigerator cool with minimum effort. And if the shape is such that the surface area is small, less heat will leak back into the refrigerator. The amount of energy also depends on the temperature difference between the temperature desired for the refrigerator and the ambient temperature.
