Infomation About Electrical Ground

An electrical ground is a reference point built into the electrical circuit, used as a baseline when measuring other electrical currents. It also serves as the return path for an electric circuit. The purpose of an electrical ground is to allow any spikes in electricity to be directly away from the electric circuit and into the ground where it is harmlessly absorbed. An electrical circuit is designed to carry electricity, regardless of the form. Static electricity can build up in a circuit through poor insulation and create a dangerous situation, where the circuit is overloaded with electricity. The electrical ground is the escape route for this additional energy and is built into most electric devices. Electric ground is a term that is used in airplanes and on boats, where there is no connection to the ground. In Great Britain, the term used is earth or earthing to indicate that an electrical circuit is ground. In the installation of mains electricity, an electrical ground describes a wire connected directly to the earth. The wire usually runs along the body of the actual metal equipment cases. The purpose of the wire is to divert any excess electrical current away from the equipment. Should an electrical current pass through the electrical ground, the circuit is broken and the equipment will not receive any more power. However, the electric ground stopped the additional current from destroying the equipment. If an electrical ground is not properly installed into the ground itself, then the electrical energy remains in the circuit and can cause a fire and explosion. Electrical power equipment usually comes with a permanently connected grounding conductor. Most electrical plugs have three prongs, arranged in a triangular formation, with two vertical prongs parallel to each other and one round conductor located below. This third conductor has a pin that connects it to the electrical ground built into the outlet. Electrical outlets are all designed to accommodate the three prong plug. When the outlet is being installed, the third prong is connected to the electrical ground. This method ensures that each item plugged into an electrical outlet can be linked to the ground. Never break off the third prong of an electrical plug, as this is the electrical ground for your electronic equipment. If it breaks off, return the product to the manufacturer and do not attempt to repair it yourself or use it without the third prong. The power supply to consumers fluctuates widely and any excess current can cause an electrical surge without an electrical ground to protect you.
