THE RELEVANCE OF GROUNDING IN AN ELECTRICAL SYSTEM

The grounding wire is one additional route for the electrical current to be safely returned to the ground without causing a person any harm in case there is a short circuit. At that very moment, the short would result in the current flowing through the grounding wire which in turn would cause the circuit breaker to trip or the fuse to blow.

When grounding wires are used on any portable devices or power tools, they are made far safer when a third prong (ground connection) is used. There are times when people cut off their power tool’s or extension cord’s ground tab because the electrical outlet they are trying to use doesn’t have a grounding point, and this is a definite mistake.


UNGROUNDED APPLIANCES – THE DANGERS

Ungrounded extension cords, power tools, appliances or electrical boxes can pose a danger if there is no grounding path except through you. Without a ground wire, your body becomes the point through which the ground path gets completed and you can experience an electrical shock. This is more common if you are using older appliances that have cloth-wrapped wiring. Modern-day appliances have three-pronged cords that include the ground for protection.


THE IMPORTANCE OF GROUNDING

It is important to ground electrical currents because:

#1 Protects against overloads in electricity

Grounding electrical currents helps protect your appliances, those using the appliances as well as your home from electrical surges. In the event of a power surge or lightning strike the high voltage of electricity that flows through your systems helps the exces
