The short answer to this question is simple: money! Why have an engineer do blueprints and drawings for your building? Because you need to have a plan before you start construction. Could you imagine a construction company showing up at a site without blueprints and not knowing if they were going to build a skyscraper…
My electrician told me that they were registered; however I now believe that they are not, as they have not given me a certificate. What should I do? First you need to find out whether the electrician you used is actually registered. To do this, contact the operator of the scheme they have claimed to…
We can measure the electrical resistance of almost anything, including soil. Understanding the resistance to electricity that the soil provides enables engineers to draft and design grounding systems to meet engineering specifications. The difference between resistance and resistivity is relatively simple. Resistivity is resistance placed in terms of weight or volume, such as, “the resistance…
Electrical grounding or “Grounding” originally began as a safety measure used to help prevent people from accidentally coming in contact with electrical hazards. Think of your refrigerator. It’s a metal box standing on rubber feet with electricity running in and out of it. You use magnets to hang your child’s latest drawing on the metal…
An electrode is anything placed into the ground that is used to provide an electrical connection to the earth. The most common electrode is the copper-clad driven grounding rod. This grounding rod is essentially an 8 or 10-foot long shaft of mild-steel, thinly coated with copper and driven into the earth. The process of installing…

Electrical Grounding Frequently Asked Questions What is Ground Potential Rise? I’ll try to answer this in as basic terms as I can here in the FAQ section. View our detailed page for information on what is Ground Potential Rise. A Ground Potential Rise or GPR is a phenomenon that happens when a large amount of…
Electrical installations should be tested often enough that there is little chance of deterioration leading to danger. Any part of an installation that has become obviously defective between tests should be de-energised until the fault can be fixed. You should have your electrical installation inspected and tested by a person who has the competence to…
1. Electric current is measured using what device? 2. True or false? Batteries convert chemical to electrical energy. 3. In terms of electricity, what does DC stand for? 4. The wire inside an electric bulb is known as the what? 5. Conductors have a high or low resistance? 6. True or false? The concept of…
Electric Bicycle FAQs What are Electric Bicycles? Electric Bicycles, or e-bikes for short, are simply traditional bicycles that have been fitted with a battery and motor that offer the rider a level of electrical powered assistance. How fast will an electric bicycle go? The law states that, in the UK, the motor of an electric…
