Standard 3 Pin UK Plug 3A, White

Product Information

As modern day living has progressed and technology improves, lightbulbs are changing over to LED. A lot of the LED lightbulbs are 5 W (that’s one 20 th of a hundred watt lightbulb) so a calculation for this would be: T o the untrained eye it may not be obvious and you can be forgiven for missing the issues, for now. It’s bigger than in other countries on purpose; the designer didn’t do that to annoy or frustrate – its size makes it safer, how?

The wires are cut to the wrong length– To be fully correct, the coloured wires should have been cut at better lengths so that the white covering is fully into the plug before it is secured. Most plugs actually have a cable grip that screws across the main outer insulation sheath. Fuses and circuit breakers serve a very similar function - both break electrical circuits in the event of a current surge or short circuit. However, there is a crucial difference. Circuit breakers are switches, and like all switches, they can be reset once they have been flipped. Most fuses, though, can only be used a single time. Once they have blown, they must be replaced. They are, by definition, a weak link - entirely by design. The time taken for a particular type of fuse to blow is called the fuse speed. The three principal fuse speeds available 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 caseHowever a 13 amp fuse would be fitted as standard into the plug by the manufacturer, any fuse lower than even the 10 amp would fail.

You may be surprised to learn but there is a very high percentage of British adults who do not know how to wire a plug. We as PAT testers come across literally thousands of badly wired plugs every year – it is our job to make sure plugs are wired correctly. 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,.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:

In the UK, the majority of domestic appliances can stay with a pre-fitted moulded plug. The plugs have either a 3 amp or a 13 amp rated fuse - It is very rare that you find anything inbetween although there are other fuses available. The plug with its fuse for the appliance make the minimum protection required for your piece of equipment/appliance. An incorrect fuse however will continually blow if it is incorrectly rated or fail to protect your equipment from a catastrophic meltdown if it is too high. Each coloured cable has copper wires inside because copper is a good conductor of electricity. The outer layer (what we tend to refer to as the “wire” is flexible plastic, as plastic provides good insulation; this wire is commonly referred to as the “ flex“; short for the “ flexible cable“.

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 The fuse in the plug is not fitted to protect the appliance, although in practice it often does this. Appliances are generally designed to European standards for use throughout Europe. In most countries the plug is unfused. If an appliance needs a fuse to comply with the standard it must be fitted within the appliance. The fuse in the plug protects against faults in the flex and can allow the use of a reduced csa flexible cable. This is advantageous for such appliances as electric blankets, soldering irons and Christmas tree lights, where the flexibility of a small flexible cable is desirable. How to wire a plug– this article is intended to guide you in wiring a plug or rewiring a plug, so that when you have to change a plug at home or work you know how to do it correctly. Set out below is a grid which will give you an indication as to which fuse rating will typically be used within your appliance. I have a pre-fitted moulded plug on my appliance and there is no fuse? I have no idea what type or fuse rating I require!"

Kettles have a wide range of wattages depending on if it is a slow boiling kettle, or a rapid boiling kettle. The simple calculation is watts divided by volts equals amps. After you have calculated this, it is a simple case of adding around 10% to the value and choosing the nearest fuse to match. This is a more precise method then just guessing should you require a 3, 5, or even 13 amp fuse. Replacing the incorrect fuse with the correct one will avoid the risk of you blowing the fuse. The 10, 30, 100, 300mA residual rating is the residual rating. This is the live to earth fault current that the device will detect. 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. Fast Acting Fuses: these are a more general-purpose fuse typically used with cabling and sturdier components. They are also known as Fast Blow or F-Type fusesSurface 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. Resettable SMD fuses, by contrast, can be used multiple times. They function in a similar way to resettable thermal fuses and are available in multiple sizes and capacities. Striker Fuses Switch fuse units distribute current while shielding cables and devices from the damage that would be caused by power fluctuations along a particular electrical circuit. Switch fuse units are used in industrial and commercial buildings as well as domestic properties. HRC Fuse Types High rupturing capacity (HRC) fuses feature a transparent capsule around the central resistor.
