Yes you can. It will provide better protection because it will blow quicker than a 20 amp if there is a fault in the circuit.
Not advisable. If the normal current is little more than 15 amps, then the fuse will blow. If the actual current is less than 15 amps, then it would work.

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 20 amp fuse to replace a 15 amp fuse?

In a temporary situation yes but it should be replaced with the correct size as soon as possible. No, the fuse is meant as protection for the circuit. Installing a larger fuse can cause the wiring to burn if a short occurs.


Can you use a 15 amp fuse instead of 20 amp?

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.


How do you change a 15 amp outlet to a 20 amp outlet?

The only way you can change a 15 amp to a 20 is you have to replace the 14 gauge wire going to it with a 12 gauge wire, then replace the 15 amp breaker with a 20 amp breaker. You can put a 15 amp outlet on a 20 amp circuit as long as there is more then one receptacle. A double receptacle counts as two receptacles. Steve Green Coeur d'Alene, Idaho


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

No. Always replace a fuse with the same type and rating.

Can you replace a 15 amp fuse in your car with a 20 amp fuse for a cigarette lighter It keeps blowing the 15 amp?

No, you could overload the wiring and start a fire.


If your fuse box supports 20 amp fuses can you replace one current 15 amp fuse with a 20 amp fuse?

The purpose of a fuse it to protect the wire that goes to the load. A 15 amp fuse protects a #14 gauge wire. A 20 amp fuse protects a #12 gauge wire. To answer your question if the wire size is #12 coming from the 15 amp fuse now then it can be upped to 20 amp fuse. If it isn't then you are taking the risk of overloading the #14 wire with a 20 amp fuse. This can lead to insulation failure of the #14 wire, overheating with the possible outcome of a fire breaking out somewhere in the circuit.

Can you replace a 10 amp fuse with a 20 amp fuse?

NO! Using a larger amp fuse defeats the purpose of the fuse to protect the wiring in the circuit. This can cause a fire. Always use the correct amp fuse for that circuit.

I believe that it's either a 10 amp fuse or 20 amp. Check your fuses out. It should tell you.

Can I replace a 10 amp fuse with a 20 amp fuse in the AC?

No, you cannot replace a 10-amp fuse with a 20-amp fuse. Fuses are meant to guard your wiring and equipment by melting or 'blowing' before the wiring, itself, melts and causes a fire. It is safe to use a smaller fuse than called for, but never, ever is it safe to use a larger fuse than called for.
