protects the wiring and the appliance if something goes wrong. cities. A 13A fuse contains a low melting point For plugs that did not come fitted to the appliance, check that the cable is connected correctly. should be rated at a slightly higher current than the device needs: Circuit breakers act as resettable fuses. This These are automatically operated electrical switches that protect electrical circuits from overloading or short circuiting. EU-Safety 2019, Luxembourg, 3rd - 4th October 2019, Unravelling Product Risk Assessment (Post Incident), Electrical Product Safety Conference ONLINE 2020, Inspection, testing, certification and reporting, Minimum standard for inspection and testing of rented domestic accommodation, Electrical Installations in Flood Prone Areas, Electrical Incidents in the Media Aug-Nov 16, Recall Review – December 2016 to April 2017, Investigation into UK socket-outlets incorporating USB charging points. Electricity can be hazardous. Electrical energy is current multiplied by voltage and time. The blown fuse cuts off the electricity to stop the lead and appliance from overheating and causing a fire. If the https://www.electricaltechnology.org/2014/11/fuse-types-of-fuses.html It is a deliberate weak link in a circuit which will 'blow' if an electrical appliance or extension lead draws too much current due to either an overload or a fault. Look for signs of overheating, such as discoloured casing or cable. The fuse in a plug is a safety device designed to protect the lead rather than the appliance. Plugs for appliances rated between about 700 watts and 3000 watts (the maximum rating of a wall socket) should be fitted with a 13-amp fuse (coloured brown). An electric fuse is a safety device, which is used to limit the current in an electric circuit. The use of fuse safeguards the circuit and appliances connected in that circuit from being damaged. The brown (previously red) plug wire goes to live (L). An alloy of lead and tin is used as a material of fuse because it has low melting point and high resistivity. The fuse clips securely into its holder. If you have to replace a fuse, it's essential, having checked and corrected the reason for the fuse blowing, to replace it only with another of the same rating. However, 5 Amp fuses are still used in some older equipment and are available to buy. Check that the plug cable is firmly clamped into the plug and no coloured plug wires are showing. With the help of fuse electric equipment work efficiently and safely for long life. Plugs and their cables can be damaged with use. Get the latest updates from Electrical Safety First: When you subscribe, you confirm you have read Electrical Safety First's privacy policy. Is the cable cut, nicked or damaged in any way? 257376) and Scotland (No. The lives of television, computers, radios and other home appliances may also put at risk. Read about our approach to external linking. Sign in, choose your GCSE subjects and see content that's tailored for you. Fuses are used for the prevention of home appliances from the short circuit and damage by overload or high current etc. There should be no joints and no repairs with insulating tape.

As a rule of thumb, fuses … They detect faults and then stop the flow of electricity. As a rule of thumb, fuses are rated according to the power rating of the appliance. It should not be loose and there should be no signs of overheating. Is the cable securely attached to the appliance and the plug? The three basic purposes of fuse are - To protect electric circuit and equipments- It protects electric circuit and equipments from overcurrent or short circuit current. 13A Fuse – Washing machine, dishwasher, microwave, kettle, toaster, iron. It is a deliberate weak link in a circuit which will 'blow' if an electrical appliance or extension lead draws too much current due to either an overload or a fault. Here’s how to check the common, square-pin 13-amp plug used in all modern appliances such as hairdryers, vacuum cleaners and microwaves. ©2020 Electrical Safety First is the campaigning name of the Electrical Safety Council, a registered charity in England and Wales (No. Different types of fuses. The fuse breaks the circuit if a fault in an appliance causes too much current to flow. You may opt out of receiving email updates at any time by using the unsubscribe link in the emails. Mind The Gap - Are You Recall Ready To PAS 7100? Excessive current is most likely to be caused by three things: Incorrect wiring - wrong connections as a result of human error Fuses and circuit breakers protect electrical circuits and appliances. This protects the wiring and the appliance if something goes wrong. Plugs for appliances rated up to about 700 watts should have a 3-amp fuse (coloured red). The most common are 3 A, 5 A and 13 A. Our tips from experts and exam survivors will help you through. The fuse is the correct size and meets British Standard BS 1362 – see the manufacturer's instructions if you are not sure what fuse to use. Manufacturers have now standardised plug fuse ratings to be either 3A or 13A. A common UK plug is generally fitted with a 3A or 13A fuse. The fuse contains a piece of wire that melts easily. The screws holding the three plug wires are tight. Remove the plug from the socket, and remove the cover. 3A Fuse – Table lamp, standard lamp, television, video, computer, mixer, blender, fridge, freezer, power drill, jig saw, soldering iron. If we don’t use fuses, electrical faults occur in the wiring and it burns the wire and electric appliances and may starts fire at home. We have developed a plug pin gauge which allows you to perform some quick checks to help identify a sub-standard or counterfeit plug. The cord clamp holds the cable securely and that both of the screws are tight. The green and yellow (previously green) wire goes to earth (E). Fuses in plugs are made in standard ratings. Fuse is a protective device used in electric circuits. The fuse in a plug is a safety device designed to protect the lead rather than the appliance. The blown fuse cuts off the electricity to stop the lead and appliance from overheating and causing a fire. Insulation, earthing, fuses and circuit breakers help to protect us from electrical injury. It’s a good idea to check plugs and plug wires regularly.
