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.

It is not recommended to replace a 20 amp fuse with a 15 amp fuse as it may not provide enough protection for the circuit. Using a lower amperage fuse can lead to overheating and potentially cause a fire hazard. It's best to use the correct amp fuse as specified by the manufacturer.

Yes, but a 20 amp fuse will not protect the #12 conductor from an overload condition like a 20 amp circuit breaker will. The fuse will only protect against high current in a circuit.

you misspoke a 20A fuse offers far more protection than any circuit breaker

small circuit breakers are sometimes rated for less than 5000A on AIC

small cartridge fuses are rated 200,000 amps

circuit breakers usually fail by welding contacts together on a short

fuses open

Type 1 circuit breakers are the worst possible choice

similar to the clixon in the coffemakers they reset after an arbitrary cool down period and have burned quite a few houses down.

now they must have two fuses in series with the clixon

these are common in battery chargers if the battery is very low they deliver all the power the circuit will supply then open for a while and try again

Type 2 circuit breakers are a bit better they will reset only after removing power

and restoring then will apply full power until they notice the overload again.

Perhaps for sump pumps you could pump out the basement

unplug the sump pump plug it back in, find the rock jammed in the impeller

plug it back in and try again.

Type 3 the only kind almost as good as a fuse must be manually reset

you may have to run up and down the stairs ten times before you notice your fondue pot has melted thru its cord and it needs to be unplugged before you can get the superbowl to come back on.

a fuse will never reset and you are more inclined to spend a couple minutes to find the problem before spending $1 for a new one

How do you change from 15 amp fuse to 20 amp fuse?

It is not recommended to replace a 15 amp fuse with a 20 amp fuse as this can overload the circuit and pose a fire hazard. It is important to use the correct amperage fuse that is specified for the circuit to prevent damage or danger. If you are experiencing frequent blown fuses, consult an electrician to address the underlying issue.


Can you replace a 20 amp fuse in your car with a 25 amp due to the fuse keep blowing?

No, it is not safe to replace a 20 amp fuse with a 25 amp fuse. The fuse is designed to protect the circuit from overloading, and using a higher amp fuse can lead to overheating and potential fire hazards. It is important to troubleshoot and address the underlying issue that is causing the fuse to blow rather than increasing the fuse rating.


What colour goes to fuse in American wire?

The standard color coding for fuses in American wire is as follows: 15-amp fuse: blue 20-amp fuse: yellow 30-amp fuse: green


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

No, it is not safe to use a 20 amp fuse and wire rated for it in a 15 amp outlet. The outlet is designed for a maximum of 15 amps, so exceeding this limit could lead to overheating and potentially start a fire. It is important to use components that are rated for the appropriate amperage to ensure safety.


What is a common fuse rating?

15 and 20 amps for receptacles and lights, and anywhere from 20 to 60 amps for dedicated loads such as water heaters and air conditioning. The fuse size MUST be matched to the load and wire size, you cannot just arbitrarily pick one!

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 20 amp fuse with a 10 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.

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.
