Electrical Wiring – Mountain View – What is a ground?
The first article in this series on electrical wiring acts as the table of contents for the series.
All modern electrical systems for homes in the US and Canada are grounded.
What this means, is somewhere on your property, there is a copper coated ground rod driven six or eight feet into the earth.
The ground bus in your main panel is connected to this ground rod via a wire that is clamped to it.
Every circuit in your home then has a ground wire which is connected to the ground bus in your panel.
This is done for safety.
All the metal parts of the electrical system in your home, be they the panel box itself or metal junction boxes, light fixtures, etc, are grounded via a ground wire.
This way, if the insulation of a hot wire ever fails and comes in contact with the metal, the metal will not become hot and be a potential point of electricution.
Instead, it will cause a short circuit that will trip a breaker.
If you need a professional for your electrical wiring needs, we would very much appreciate an opportunity to be of service.
