No, you cannot put a 30 amp fuse in a 20 space. The reason for this is that the 30 amp fuse would allow more current to flow through than what the 20 space is rated for and this could cause damage to your electrical system or start a fire.
- Check the amperage of your fuse box
- Find a 30 amp fuse that fits your box 3
- unscrew the 20 amp fuse currently in use and screw in the 30 amp fuse 4
- tighten the new fuse

Can I Use a 20 Amp Device on a 30 Amp Circuit?
No, a 20 amp device cannot be used on a 30 amp circuit. The 20 amp device would overload the circuit and cause it to trip.
Can You Use a 30 Amp Fuse in a 15 Amp?
No, you cannot use a 30 amp fuse in a 15 amp circuit. The reason for this is that the fuse is designed to protect the circuit from excessive current. If you were to use a 30 amp fuse in a 15 amp circuit, it would allow too much current to flow through the circuit and could potentially cause damage or even start a fire.
Can You Put a 30 Amp Fuse in a 25?
No, you cannot put a 30 amp fuse in a 25. The difference in amperage between the two sizes is too great and could cause serious damage to your electrical system.
Conclusion
No, you cannot put a 30 amp fuse in a 20 slot. The amperage rating for a fuse is too high and will cause the wires to overheat and potentially start a fire.
