A standard 13A plug (BS 1363) is designed to fit cables up to a maximum of 1.5mm2. The maximum current capacity of a 1.5mm2 cable is 15A and should be protected by a maximum fuse size of 13A. A 20A fuse in a domestic 13A plug should never be used.
What is a Type W fuse?
Type-W fuses are an older style of fuse utilizing an Edison base and are all but obsolete today. They are general-purpose plug fuses and are fast-acting—that is, they have no time-delay fuse element and quickly interrupt the circuit once the fuse’s rated amperage is exceeded.
What does W mean on a fuse?
Type W: These fuses react fast to the amperage if it exceeds the rating. These fuses ae used for general purpose circuits and lights. They are not recommended for circuits with motors.
Can you use a 13 amp fuse in a 3 amp plug?
Yes of course there is. The cable or flex attached to the gas fire is purely to supply the ignition. The flex provided is not rated to 13A because the ignition requires very little current and so the flex requires protection by a 3A fuse.
Can you use a 3 amp fuse in a 13amp plug?
Can I replace a 15-amp fuse with a 20-amp fuse?
The answer: It’s possible, but not advisable without an electrician evaluating the situation. You should never just upgrade from a 15-amp breaker to a 20-amp one just because the current one is tripping. Otherwise, you may burn your house down via electrical fire.
What amp fuse do I need for a cooker?
Electric cookers require lots of power to operate since they generate intense amounts of heat. This means that you need to get at least a 13 amp fuse, although newer models will most likely require a 32 amp fuse (read your product’s specifications to check its exact amp rating).
