Undoubtedly, one of the greatest ground-breaking achievements in human history is the ability to harness electricity as an energy source. The domestic electrical grid was designed by electrical engineers with several built-in fail-safes to protect your home and property from potentially fatal electrical shocks and fires, even though electricity used improperly can become dangerous. A grounding wire, which has been regularly required for residential electrical codes since the 1960s, is one of these safety precautions that are most frequently used.
A ground wire is what?
At its heart, electricity is predictable; positively charged electrical energy constantly seeks the shortest route toward the negatively charged ground. Residential Electrician Sydney have long known how to control this path in order to harness the electricity and power our homes, despite the fact that the electrical pulses in a household grid are also travelling along the quickest path to the Earth. However, electrical grids frequently experience electrical arcs and surges, which electricity cause extra to search for a new route to the ground. This is where a ground wire can help; they are made to provide extra electricity with a safe and efficient path to the earth.
What Kinds of Wires Are Used as Ground?
A ground wire is designed to safely channel excess energy to the ground, and nearly all of them are made of highly conductive copper wire that has been installed in green and yellow plastic for easy identification. To distinguish the ground wire from the other electrical wires, the ground wire's color—green with a yellow stripe—is almost always used. Several ground wire characteristics can change depending on the requirements of the electrical grid they are grounding. Here are a few examples of ground wires of various types.
The most prevalent ground wire type in residential homes is bare copper because it is uninsulated and a good conductor.
Green 6 THHN ground wire is protected from the elements and is typically used in outdoor electrical outlets.
Gauged Copper: Available in a range of sizes, gauged copper enables larger surges to easily pass along the ground wire when necessary. An informative ground wire size chart that details the gauge of copper that is suitable for various electrical grid sizes can be found.
How To Reset A Tripped Circuit Breaker And Why
A circuit breaker is a security feature for your home or property that is part of an electrical grid. It not only enables you to turn off the entire or a portion of the electrical circuit, but it also serves as a fail-safe for your electrical grid by shutting off, or tripping, in the event of a system overload or electrical surge. By doing this, electrical fires and property damage to your home are avoided. Your home's circuit breakers may trip for a number of reasons, including:
- Electrical overloads happen when an electrical circuit's energy requirements exceed its capacity, as would happen if too many electrical appliances were plugged into a single outlet.
- Short circuits happen when a neutral wire comes into contact with a charged or live wire, which is not what should happen. The circuit breaker is intended to shut off the circuit because this results in surges in an electrical system that can be extremely dangerous.
- A live wire touching a ground wire can cause a ground fault surge, which is similar to a short circuit in that it causes a surge and a trip to happen.
