Is there a safety issue between having the old rewirable fuses instead of circuit breakers?
ANSWER
Yes, it is a safety issue.
There are three main issues with rewirable fuses:
- First, after a fuse blows to protect your home from an overloaded circuit, it splatters copper over the procelaine fo the fuse holder. This can then bypass the fuse and slow the fuse blowing next time.
- Secondly, the majority of insurance companies now require that rewirable fuses be replaced with circuit breakers.
Finally Rewirable fuses react a lot slower than circuit breakers. A fault on your wiring can turn into a fire before a fuse will blow therefore they are unsafe. Replace them if you're having electrical work undertaken on your switchboard.
