Can you replace 20a fuse with 25a fuse?

No, you should not replace a 20A fuse with a 25A fuse. Fuses are designed to protect circuits by breaking the connection when the current exceeds a certain level; using a higher-rated fuse can result in overheating and potentially cause fires or damage to the wiring and connected devices. Always replace fuses with the same rating to ensure safety and proper functionality.
