Can I use 30 amp instead of 20?

As the title suggests, I was curious if it would be possible to up the voltage on the fuses I am using.

Changing fuses will not do anything to the voltage. Fuses limit current.

To answer your main question, No. Unless the wire the fuse is protecting is #10 copper, AND the circuit is not a receptacle or general purpose circuit, the circuit will likely only be limited to a 20 amp or smaller. On that same line, the fuse can only be a 20 amp if the wire is #12 copper, or 15 amp for #14 copper wire.

No and in fact the two 20 amp fuses probably need to be changes to 15 amps. Fuses are to protect the wiring. On a panel that old the wires are probably #14. Without correct size fuses the chance of fire is greatly increased.

to up the voltage on the fuses I am using.
Fuses are rated in amps.

Please give us full details of your situation and problem and we may be abel to help you.

That 30A figure on the panel is referring to the total ampacity of that fuse box.

Thank you guys for the prompt response, I just moved into a new apartment and the power in the kitchen recently went out. I will go down to the local appliance store and switch it out to a 15 amp fuse.
