Standard 3 Pin UK Plug 3A, White

Product Information

What is really great about Bright Spark Electrical is that they communicate well and get the job done precisely exactly as agreed and bang on time. The job is thoroughly discussed beforehand, you know who is coming and when and have a full list of the parts to be installed. They perform tasks efficiently with no mess. They have done jobs for me in Tunbridge Wells, both in the Culverden Down area and at High Brooms and I would recommend them 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 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. Hi, as already explained both r good ideas, plug would be easier, if u change for switch furs spur , u would have to test ring continuity, ect which gets technical! 2018-01-12T17:45:01+00:00 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? 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.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. 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. Wiring a plug seems to cause all kinds of confusion, which it shouldn’t really as it’s not that complicated, if perhaps a little bit fiddly. When we’re working we actually come across people quite often who jest us with things like –“ what’s the point of PAT Testing; anyone can wire a plug“, only for us later to find an incorrectly wired plug, done by that very same person!

Thermal fuses are used in settings that produce heat. The internal resistor blows when the surrounding temperature reaches a certain level and the fuse must then be replaced with a fully compatible new one. I'd be wonderingwhy the PAT testers are asking. have they found devices with blown fuses, are they doing the replacing of fuses. If so, even a small degee of electrical competence would help them make their decision.Bottle fuses are bottle-shaped, with ends in two different sizes. The lower end is precisely aligned with the screw holes in the circuit adaptor, so no other type of fuse can be fitted into that slot. These fuses also feature an indicator in their head that drops out when the fuse blows, to show that there has been a problem in the circuit. Once this occurs, the fuse must be replaced.

The standard UK plug is like no other in the world; it has three chunky, metal pins when most others just have two, and the plug in the main is bigger than elsewhere in the world – how can they get their electricity on such a smaller unit than us? So from this calculation the ideal fuse would be the one amp fuse, but again, most manufacturers will have put in a three amp fuse. Typical example: A Kettle. Fuses are very simple components. Inside each is a thin metal strip or wire called a resistor that forms a link in an electrical circuit. A number of different metals are used to make resistors. Tinned copper wire is a popular choice. This is copper which has been coated in a thin layer of tin to protect against corrosion. 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.

You can only compare up to four products at a time.

Depends on why your PAT testers are asking, if the equipment is blowing 3amp but not 5amp fuses, it’s less of a risk having 5amp as they don’t create a fire hazard.
