Electrical grounding

A grounding electrode conductor (GEC) is used to connect the system grounded (neutral) conductor, or the equipment to a grounding electrode, or a point on the grounding electrode system. This is called system grounding and most electrical systems are required to be grounded. What is the definition of electrical grounding? How do you test electrical grounding?

Grounding is a principle of electricity that sometimes puzzles homeowners. In essence, the grounding system in a residential wiring system serves a backup pathway that provides an alternate route for electrical current to follow back to ground in the case of a problem in the wiring system. Think of your refrigerator.

It is a metal box standing on rubber feet with electricity running in and out of it. Other articles from esgroundingsolutions. When the subject of electricity comes up, you will often hear about electrical grounding , or just ground. For example, an electrical generator will say, Be sure to attach to an earth ground before using, or an appliance might warn, Do not use without an appropriate ground. Grounding prongs are the third prong found on many modern electrical plugs, providing a path to ground if a circuit fails by drawing current through the outlet via the grounding wire.

Most tools and appliances today have a grounding prong in their plugs, and most power outlets and extension cords today are designed to support the grounding prong. NATIONAL ELECTRICAL CODES NEC 250. Abstract: This is a discussion of the basic principles behind grounding systems and how grounding is related to safety and the effective operation of circuit protection devices such as fuses and circuit breakers.

A safety measure devised to prevent people from getting shocked if the insulation inside electrical devices fails is called Earthing. To answer our initial question, the third pin in the plug is actually the “Earth” or “Ground” connection of the electrical appliance. There are two major reasons for ground fault protection on electrical circuits. The equipment grounding conductor (EGC) on electrical tools, appliances, and electronics provide ground fault protection on metal parts. This should eliminate the chance of an electric shock during the event of a ground fault.

A GFCI outlet installation does not protect equipment from power surges. Grounding provides a safe, alternate path around the electrical system of your house thus minimizing damage from such occurrences. Generally Black wire is used for this as a nomenclature. It facilitates a physical connection between the ground and the electrical equipment and appliances in your home. Grounding a tool or electrical system means intentionally creating a low-resistance path to the earth.

When properly done, current from a short or from lightning follows this path, thus preventing the buildup of voltages that would otherwise result in electrical shock, injury and even death. Modern homes are filled with various types of electrical appliances. These appliances go a long way in making life easier and more comfortable. The topic of grounding and bonding is a never ending area of confusion.

The difference between a service panel and a sub panel is also muddy in many minds. Here are the basics on panels and grounding. The ConduDisc utility pole ground plate is designed and manufactured in compliance with the CSA Standard C22.

The grounding system provides a low-impedance path for fault current and limits the voltage rise on the normally non-current-carrying metallic components of the electrical distribution system. Grounding and bonding are the basis upon which safety and power quality are built. In the US, many 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 ground built into the outlet. Commonly called a lightning ro it is really a grounding rod.
