Yes you can but you are setting yourself up for a big problem. There is a reason the 20 amp fuse is blowing. By installing a bigger fuse it allows the current that is causing the 20 amp fuse to blow to stay in for a longer period of time. This can cause excessive heating and melting of the wires on the circuit that is blowing on a 20 amp fuse. Trace the wire and find the fault. Always use the manufacturer's recommended fuse sizing for your own protection.

Can a 25 amp fuse replace a 30 amp fuse in a central ac unit?

Yes, as long as it doesn't blow. You can always go lower with a fuse, but not higher.


Can you use a 1.5a 125V fuse to replace a 5a 125V fuse?

It depends on what you are powering with the circuit, but probably not. The 1.5 amp fuse would blow in normal operation of the device.


Will it work if you replace a 1.25 amp 125 volt fuse with a 1 amp 250 volt fuse?

Yes you can do that as long as it will fit in the fuseholder. It is acceptable to replace a lower Voltage Rated fuse with a higher but NEVER replace a higher with a lower. There are several things to consider when replacing a fuse: 1) The minimum voltage rating of the fuse is equal to or higher than the voltage of the circuit you are placing it in 2) The Amperage rating of the fuse does not exceed the capacity of the circuit you are trying to protect. Always replace a fuse with one that has the same amperage rating. 3) The interrupting rating of the fuse is sufficent for the capacity of the circuit supplying the fuse. If replacing a fuse always use one with an interrupting capacity equal to or greater than the fuse you are replacing.


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

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


Where can you find a 10 amp 125 volt fuse at?

Assuming the wiring is sized for 12 amps, you can replace your fuse with any 12 amp fuse or smaller and with a voltage rating at or above what you expect to connect to it. The amp rating protects the wire, so you cannot go above what the wire can handle. The voltage rating is the max voltage that it can safely protect, so you cannot use a fuse with a lower voltage rating than you expect to connect to.

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.

Can a 30 amp fuse replace a 40 amp fuse on a lawnmower?

You can replace a higher rating fuse with a lower rating provided it works with the device without constantly blowing. So try the 30 amp fuse in your lawnmower and if it doesn't blow and the mower works okay, you are fine. If it blows you will have to go back to 40.

A 3 amp fuse sounds pretty small for that application. I would suggest at least a 5 amp, and probably a 10 amp.
