Rewirable Fuses
ANSWER
Rewirable fuses are a safety device used between the 1920's to the 1970's in New Zealand.
Rewirable fuses are used to protect the cabling in your home.
The fuse is made of porcelaine with a single strand of fuse wire of the size to suit the size of the cable. The fuse wire is rated to only carry a certain load or current through it.
When faults are present on the cable it will blow the fuse.
Re-wirable fuses allow the homeowner to place a replacement fuse wire in the holder, this must not exceed the rating printed on the front of the fuse holder.
With the repeated blowing of the fuse (over years) it can plaster the inside of the fuse with spattered copper so that the wire no longer is the wire or conductor, this is an extreme FIRE RISK.
Rewirable fuse wire can carry an overload on it for a considerable length of time which can cause a FIRE.
Rewirable fuses are to be replaced by Electricians when seen and upgraded to MCB's. Do you have rewirable fuses in your home, contact us and sleep safe at nights.
