Sometimes though, there is a misconception that equipment or case grounding is optional. Grounding wires provide an integral part of the electrical safety and must always be seriously considered. Here are a few reasons why grounding equipment is so important. In summary, there are essentially 3 parts of an electrical system that are critical to functionality and safety. Proper grounding and bonding is a critical part of an electrical infrastructure that must not be overlooked.
The grounding wire is required by the National Electrical Code to be a bare wire, or if insulated, a green or green with yellow colored insulation. English Spanish. Enable Cookies. Go Back.

When a conductive surface, like metal, is not grounded and becomes electrically energized, it can carry sufficient voltage to administer a fatal shock. Imagine that an electrical issue occurs, like a lightning strike or a power surge, where no grounding exists.
Electrical code requirements making ground wiring standard were phased in during the s, so most modern homes have grounded outlets and electrical panels throughout. The purpose of a ground wire is to give excess electrical charges a safe place to go. The solid mass of earth below our feet has a negative electrical charge, which means positive electrical charges are naturally attracted to it.
A ground wire helps those positive charges get to the ground in a safe, direct and controlled way, where they can be discharged without the risk of electrical shock or fire. Excess electrical charges are common in any home.
