Main information
What it could mean
If your installation still has fuses (more common in older setups), a blown fuse cuts power to that circuit until it's replaced.
Safety first
Don't replace a fuse with one of a higher rating than specified; get it checked if it blows repeatedly.
Next step
If fuses blow often, it's usually a sign the installation needs upgrading to breakers, which are safer and more convenient.
Frequently asked questions
Is it normal for my installation to still have fuses?
Common in older, unupgraded installations; modern breakers offer more safety and convenience.
Can I replace a blown fuse myself?
Not recommended to handle the switchboard yourself; worth getting it checked, especially if it blows repeatedly.
Is it worth upgrading the whole fuse system to breakers?
If fuses fail often, it's usually the moment to consider upgrading the switchboard.
