Periodic Inspection Explained All electrical installations deteriorate with age and use. They should therefore be inspected and tested at appropriate intervals to check whether they are in a satisfactory condition for continued service. Such safety checks are commonly referred to as 'periodic inspection and testing'. A periodic inspection will: Reveal if any of your electrical circuits or equipment are overloaded. Find any potential electric shock risks and fire hazards. Identify any defective electrical work. Highlight any lack of earthing or bonding. Tests are also carried out on wiring and fixed electrical equipment to check that they are safe. A schedule of circuits is also provided, which is invaluable for a property. How often is a periodic inspection required ?  Your electrics should be inspected and tested every: 10 years for an owner-occupied home. 5 years for a rented home. 3 years for a caravan 1 year for a swimming pool. Other times wh


Fuseboxes explained   Your Fusebox –  the fusebox also known as consumer unit should be easy to find. You should make sure you know where it is in case you ever need to turn the electricity off in an emergency. It usually contains three things, and they are used to control and distribute electricity around your home. They are :  The main switch; Fuses and/or  circuit breakers ; and Residual Current Devices. A) Main   Switch  – this allows you to turn off the electricity supply to your home. You might have more than one mains switch, for example if your home has electric storage heaters. In this case you may have a separate fusebox. B) Residual Current Devices ( RCD )  these are switches that trip a circuit under dangerous conditions, and instantly  disconnect  the electricity. If your home has one or more RCD, test them regularly. Just follow the instruction label, which you should find near to the RCD. It should read as follows: “This  installation , or part of it, i


RCDs Explained By   a Professional Electrician An RCD , or residual current device, is a life-saving device which is designed to prevent you from getting a fatal electric shock if you touch something live, such as a bare wire. It can also provide some protection against electrical fires. RCDs offer a level of personal protection that ordinary fuses and circuit-breakers cannot provide. Below are the questions most commonly asked about RCDs (click to expand answers). What does an RCD do? An RCD is a sensitive safety device that switches off electricity automatically if there is a fault. An RCD is designed to protect against the risks of electrocution and fire caused by earth faults .   For example, if you cut through the  cable  when mowing the lawn and accidentally touched the exposed live wires or a faulty appliance overheats causing electric current to flow to earth. How does it work? An RCD constantly monitors the electric current flowing through one
