Can you use a higher amp fuse for a lower amp machine?

No, you should not use a higher amp fuse for a lower amp machine. Fuses are designed to protect electrical circuits by breaking the connection when the current exceeds a specific limit. Using a higher amp fuse can lead to overheating and potentially damage the machine or cause fire hazards, as the fuse may not blow in a fault condition. Always use the fuse rating specified by the manufacturer to ensure safety and proper operation.
