What size fuse do I use in a fused spur? The size of fuse depends on the appliance or equipment that it is feeding. The calculation would be 2200 Watts divided by 240 Volts equalling 9.17 A +10% which equals 10.087 amp. So from this calculation the ideal fuse would be a fuse of around 10 A amp. The definition of a D-type fuse is a miniature circuit breaker that trips when the current exceeds the rated level by between ten and 20 times. Therefore, a 16 amp Type D breaker will trip if the current reaches between 160 and 320 amps. Type F Fuses If your car radio has stopped working, a blown fuse may be the cause. These steps will help you identify and replace a broken car radio fuse:

There are multiple different types of automotive fuses. Varying types and sizes will be needed for dealing with specific electrical equipment within the vehicle. For this reason, it is common for a single car to include many different types of fuses. Striker fuses are fuses fitted with a spring-loaded striking device that can trip adjacent switches and also indicate that a fuse has blown. Type C Fuses Fuse boxes can essentially be explained as control panels for the electrical system in a particular location. They are the location at which incoming power is divided into separate circuits. Typically, they feature a central switch controlling: A Type C fuse is actually a type of miniature circuit breaker (MCB). MCBs are a type of circuit breaker used with lower-powered circuits to cut off current in the event of an overload. Type C fuses trip circuits when the current exceeds the rated one by between five and ten times - i.e. at 100-500 amps for a 20amp device. Type D Fuses It is important to note that the section of cable coming from the battery +ve terminal to the first fuse (or battery distribution box) is effectively an unprotected part of the circuit. If there is a short anywhere along this length then it is very likely to catch fire as the first fuse will not experience the excess current. For this reason the length of cable from the battery +ve to the first fuse should be as short as possible so that damage is minimised in the event of an electrical fire.Generally in this instance you will be having a 13 amp fuse in the fuse spur, feeding down to a 13 amp fuse in your plug,. If you find that you have a three amp fuse in the fuse spur feeding down to your appliance, and using the calculations above, you have a requirement for 13 amp fuse, then the fuse in the fuse spur needs to be upgraded to the 13 amp fuse. Despite their everyday name, domestic fuse boxes now typically contain circuit breakers rather than fuses, and they are more formally known as consumer panels. However, if your property still contains a traditional model, here is how to go about changing the wire in a fuse if it blows and cuts the power to one of the circuits that run through the building.

For example, if an electric drill requiring a new fuse has a 700-watt rating, divide this by 230 (the standard UK mains voltage). The result is 3.04, so you will require a 3A amp fuse for the plug. Where Would a Type D Fuse Be Installed? When a fuse blows, the electrical supply to a particular circuit is immediately cut off. This lowers the risk of fire and prevents damage to the wiring. The blown fuse can safely be replaced without the risk of electrocution. Are Old Fuse Boxes Illegal?If replacing a blown fuse in a manufacturer-designed (factory) application, e.g. in a vehicle fuse panel, then the same type and rating of fuse should be used. If a fuse continues to blow then there must be a fault with the circuit and a higher rating fuse should never be fitted to overcome this, even temporarily. Doing this creates a high risk of component failure and electrical fire.

Fuse boxes have a number of alternative names, including control board panels, distribution boards, breaker panels, fuse boards, and fuse panels. Domestic fuse boxes are frequently referred to as consumer units. What is a Switch Fuse Unit? Cylindrical fuses are a basic design and many of the most widely used and familiar models fall within this category. HRC Fuse Types

The technical reference for a UK plug is BS 1362.

The standard blade fuse (also known as APR, ATC or ATO fuses) is the most common with many cars now using the mini blade version (also known as APM or ATM fuses). Increasing in popularity is the micro blade version (also known as APS or ATT fuses) with more widespread use expected in the future as manufacturers attempt to fit more electrical systems into the same space The majority of the time there is no identification plate on the table lamp, however we know that the maximum lightbulb wattage is going to be 100 W, so the calculation would be: As explained above, the first steps to replacing a car fuse are to locate the fuse box and the blown fuse and buy a new fuse of the same type, size, and current rating. Once you have the new fuse, you will need to carefully insert it into position within the fuse box or housing. Make sure to insert it into the correct location where the blown fuse was situated.

The time taken for a particular type of fuse to blow is called the fuse speed. The three principal fuse speeds available are: Surface mount devices (SMDs) are electrical components that sit on the surface of printed circuit boards (PCBs). SMD fuses are available in both resettable and non-resettable forms. A typical identification plate which can be found on the base of the kettle could show the following information 220–240 Volts – 50 Hz 1850 to 2200 Watts the ID plate shows that this is a kettle that is suitable for Europe 220 V (1850 Watts) and the UK 240 Volts (2200 Watts). The 50 Hz is a frequency and is not required for the calculation. When specifying a fuse for an after-market application, the key consideration is that the fuse should be the weakest point (i.e. lowest rated component) so that it always blows before any damage occurs to other parts of the electrical circuit. However, you also do not want the fuse to keep blowing under normal operation (known as a nuisance blow), so the two elements to consider are:Once you have replaced any necessary powerpoint fuses, locate your fuse box, using your torch if necessary. Ensure that the master switch is in the off position. It should be following a trip, but you should always make sure that this is the case Gently slot the new fuse into position in the fuse panel, taking care not to damage it or any surrounding fuses Kettles have a wide range of wattages depending on if it is a slow boiling kettle, or a rapid boiling kettle. Strip and midi link fuses are for higher current or 'power' applications (e.g. winch motors) with mega link fuses used for very high current applications. These fuses are bolted down into fuse holders or boxes. We will explain the different car fuse types further on in this guide, but the specific type of fuse your car needs will depend on a selection of factors. This includes the make and model of the vehicle, the existing fuse, and the electrical circuit or equipment it is designed to protect.
