The pipe is drilled with holes for connecting the earthing wires. The length and diameter of the pipe depends on the type of soil and the type of electrical installation. In this method as well, the earth pits are filled with alternate layers of charcoal and salt for inducing reactivity.
Pipe earthing is the most common type of earthing. Similar to pipe earthing, rod earthing requires the burying of a rod made of copper or galvanised iron. Electrodes are embedded in the soil and thus decrease the resistance of the earth as required. For wire earthing, several horizontal trenches are dug. Strip electrodes are buried inside these trenches. One of the most important reasons for grounding electrical currents is that it protects your appliances, your home and everyone in it from surges in electricity.
If lightning was to strike or the power was to surge at your place for whatever reason, this produces dangerously high voltages of electricity in your system. If your electrical system is grounded, all of that excess electricity will go into the earth — rather than frying everything connected to your system. Having your electrical system grounded means you will be making it easy for power to be directed straight to wherever you need it, allowing electrical currents to safely and efficiently travel throughout your electrical system.
The earth provides a common reference point for the many voltage sources in an electrical system. One of the reasons why grounding helps to keep you safe is because the earth is such a great conductor, and because excess electricity will always take the path of least resistance. By grounding your electrical system, you are giving it somewhere to go other than into you — possibly saving your life. Without a properly grounded electrical system, you are risking any appliances you have connected to your system being fried beyond repair.
In the worst-case scenario, an overload of power can even cause a fire to start, risking not just extensive property and data loss but physical injury as well. In most homes, the wiring system is permanently grounded to a metal rod driven into the ground or a metal pipe extending into the house from an underground water-supply system. A copper conductor connects the pipe or rod to a set of terminals for ground connections in the service panel.
It does this by providing a path a protective conductor for a fault current to flow to earth. It also causes the protective device either a circuit-breaker or fuse to switch off the electric current to the circuit that has the fault.
For example, if a cooker has a fault, the fault current flows to earth through the protective earthing conductors. A protective device fuse or circuit-breaker in the consumer unit switches off the electrical supply to the cooker.
The cooker is now safe from causing an electric shock to anyone who touches it. Bonding is used to reduce the risk of electric shocks to anyone who may touch two separate metal parts when there is a fault somewhere in the supply of electrical installation. By connecting bonding conductors between particular parts, it reduces the voltage there might have been.
An electrician will give you advice if your earthing or bonding needs to be improved for safety reasons. We strongly recommend that you use an electrician registered with a government approved scheme to carry out any electrical installation work you need doing.
It is therefore installed after the earthing switch. We promise we will only use your data to send you our newsletter as stated in our privacy policy. Geen spam, beloofd! Waar wacht je nog op?
