15 amp fuses are available in many different sizes and types. The correct answer to your question will depend on the type of circuit and the voltage and power rating of the electrical equipment which the fuse has to protect. Asking this type of question usually means you aren't yet ready to select fuses yourself.

Study some books about electrical wiring and appliances - and maybe also some electrical engineering technical textbooks - but in any case be sure to read and learn from your country's Wiring Regulations - in USA that is the National Electrical Code - and work out the answer to this question for yourself. If you get any answer here, you might attempt to do something you shouldn't be doing,

and that may cost someone a shock, a home fire, or their life. <><><>

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.

If the two fuses are from the same manufacturer they are likely to be the same i.e design and the only difference is the elements in the fuses are of such a nature that they will blow at those currents respectively.

If the circuit is rated for 20 Amps you can use a smaller fuse as long as it doesn't blow when the circuit is loaded.

What fuse do you use for a fridge?

Most branch circuits in kitchens are either 15 or 20 amp. if in doubt use the lower (15) amp fuse.


Can you use a 15 amp fuse instead of a 10 amp fuse for your car gauges?

It is NEVER a good idea to use a higher value fuse. The reason for the 10 Amp fuse is that it blows at 10 amps which the wire and device being protected is designed to handle. If you substitute 15 amps and that amount of current flows in your device, it may destroy the device and other things in the path of the current.


Can you use a 20 amp fuse and wire rated for it in a 15 amp outlet?

You can use the wire rated for 20 amps on a 15 amp receptacle but you can not use a 20 amp fuse on any device rated at 15 amps. This is a tricky part of the code about receptacle outlets, You can use a 15 amp duplex outlet on a 20 amp circuit. (duplex outlet two devices can plug in) If it is a single outlet then the outlet must be rated 20 amp. NEC table210.21(B)(3). ============ A 15 amp duplex receptacle can be wired to a 20 amp rated circuit. This means the breaker OR fuse protecting the circuit can be rated 20 amps if the wire is also rated at 20 amps (12 AWG). --Sparkfighter


What amp fuse do you use for a 100 watt bulb?

Fuses or breakers are used to protect the conductor to the load. A #14 wire conductor is rated for 15 amps. Most home circuitry is done with #14 wire. The minimum size breaker in an electrical panel is 15 amp so it looks like a 15 amp fuse or breaker can be used for a 100 watt light bulb.

What if you use 20 amp instead of 15 amp fuse with the same 250 volts in microwave?

In most cases the size of a fuse is not critical and so changing from 15 to 20 amp will not effect anything - BUT the function of a fuse is to destroy itself before some more expensive component gets destroyed by too high a current flow. As you raise the current rating of your fuses you increase the chances of negating their function,
