This guide reviews the basics of electrical grounding, how to safely ground wiring and how to check if. Grounding means connecting to the Earth or extending the ground connection to other things in your home, such as the metal frames and components of electrical equipment, wiring, appliances, light fixtures and receptacles — even if they're far away from the actual ground. Establishing a connection. All home electrical systems must be bonded and grounded according to code standards. This entails two tasks: First, the metal water and gas pipes must be connected electrically to create a continuous low resistance path back to the main electrical panel. The principle reason of facilitating the grounding is to enable immediate diversion of heavy fault current in the event of a circuit fault.
