Why is grounding electrical currents so important?

The Importance of 'Grounding' Electrical Current

One of the most important reasons for grounding electrical currents is that it protects your appliances, your home and everyone in it from surges in electricity. If lightning was to strike or the power was to surge at your place for whatever reason, this produces dangerously high voltages of electricity in your system.

Is a Grounding Wire Necessary?

An electrical circuit will operate normally without a ground wire because that wire is essentially not part of the conducting path that’s supplying the energy. The problem is that without a ground system in place, there is nothing to stop any dangerous voltages from being present in an electrical device or circuit. Thus, a grounding wire provides an essential safety net against the very hazards associated with electricity.

For reasons of safety, among other things, a ground wire is an essential part of any electrical circuit. Ground wires keep us safe around electrical currents, allowing electricity to have an everyday presence in our homes.

An additional ‘grounding wire’ can be attached to outlets and other electrical devices and also securely connected to the ground at the breaker box.

This ground wire is an additional path for electrical current to return safely to the ground without danger to anyone in the event of a short circuit.

The Three Main Purposes of a Grounding Wire

In any electrical system configuration, a grounding wire essentially has three main purposes.

  1. Overvoltage Protection: First, the grounding wire acts as overvoltage protection. In the case of lightning, a line surge, or unintentional contact with a higher voltage line—where dangerously high voltages end up in the system—ground wires provide an alternative path around the electric system, minimizing damage and sending that extra charge safely into the earth.
  2. Voltage Stabilization: A second purpose of the grounding wire has to do with voltage stabilization. In any system, there are many sources of electricity, with every transformer considered a separate source. The earth is the most omnipresent conductive surface and thus provides a common reference point for the many voltage sources in an electrical system. Without this, it would be extremely difficult to calculate the relationships of the various voltage sources to one another and a hazard could easily occur.
  3. Safety: Finally, a grounding system provides a certain level of safety for humans and protects property, as it removes any dangerous voltages in the case of equipment failure or system disruption and sends them safely into the earth.
