Earthing is used to protect you from an electric shock. It does this by providing a path (a protective conductor) for a fault current to flow to earth. It also causes the protective device (either a circuit-breaker or fuse) to switch off the electric current to the circuit that has the fault.

In almost every electrical installation made, earthing is used. The earthing system, also known as the grounding system, is a circuit connecting parts of the electrical system to the ground. The earthing system thus regulates the conductors with respect to the earth’s conducting surface. Hence, the term, ‘earthing’ is also quite appropriate and indicative.

The electrical system is related to the potential of the general earth mass and cannot reach a different potential. The potential of the earth is zero volts and is known as the neutral of the electricity supply. This helps in keeping the balance.

In cases of surges in the voltage, high voltages can pass through the electricity circuit. These kinds of overload can lead to damaging of devices and danger to human life. When earthing is installed with the electrical installations, the current is routed through a different path and does not affect the electrical system.

An electrical circuit has to be connected together with a lot of attention to the kind of reactions each transformer may have in response to any action on the part of any other transformer. The earth is an ever-present conductive surface and helps configure these relationships between different electrical sources and makes them easier to handle.
