If you have had a new kitchen fitted for example, you may find that you have a fuse spur above the worktop beside or close to a socket outlet. They act as terminating points for one or more neutral wires in an electrical circuit and can be used to isolate them from the power supply. This is a more precise method than just guessing 3, 5 or 13Amp and adds greater protection to your appliance, but you do risk blowing the fuse often if the operating or starting current (Amps) are very close to the fuse rating you have selected.

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.

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. The fuse in the plug protects against faults in the flex and can allow the use of a reduced csa flexible cable. 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? Double Break Combination Fuse Switch Units are a higher capacity model used to ensure an uninterrupted power supply to machinery and appliances. Once you have replaced any necessary powerpoint fuses, locate your fuse box, using your torch if necessary.

I am happy to be proved wrong but it is my understanding that the fuse rating was to ensure that the cable did not take more current than it was capable of and thus presented a potential fire risk. These housings are available in 1 through 15 circuit versions and are intended for use in wire to wire (panel mounted or . Fuses are basic safety devices widely deployed in electrical circuits for excess current or overcurrent protection.Example 2: A table lamp - There is no ID plate but we know the maximum lamp wattage that will be used in the lamp is 100w. Some of our PAT testers have asked whether it is acceptable to replace a 3 amp fuse with a 5 amp fuse if the rating moulded into the plug allows it? In the UK we operate on a 230 volts electricity supply which has the power to kill if it’s not used sensibly.

Fuses for cars function as protective devices for the many electrical components in modern vehicles. At some point in life, with all the electrical appliances we have you may need to know how to wire a plug. The fuse spur then fades down and isolates the appliance below so you do not have to uplug it should there be an appliance failiure (there is a chance you could be electricuted just pulling the socket out). The 206437-1 is a 57-position straight Free Hanging Plug with pin type contacts and 23-57 insert arrangement. Insert the new wire, threading this through the central component of the fuse (normally made from porcelain).

The AMP connector fully polarized to provide proper plug-to-cap mating incorporating a positive locking mechanism t. Even if you don’t use us for PAT, if you need a plug rewiring, we may be able to come do it for you.
