How to Rewire a Fuse
• Turn off the mains supply at the main switch. Turning off the switches which control the appliances does not isolate the mains at the fuse.
• Pull out the fuse carriers in turn to find the faulty one. This is indicated by broken or fused wire.
• Remove the broken wires, and clean the carrier. Often it is blackened by the burnt wire; these are carbon products which must be removed. Also make sure thethat clamp the wire are clean.
• Rewire the carrier, using wire of the correct rating.
• Replace the fuse and close the fuse box before re-connecting the supply.
You may notice that there is a fuse box in the mains supply before the meter. This is called the company fuse box which is sealed. It must not be opened.
If the fuses in this box go then someone from theboard must be called in to replace them. Opening the box yourself will incur a penalty.
Three-pin 13 amp plugs are available in 3A, 7A and 13A ratings. Thirteen-amp fuses are used for heating, 7A for electric drills and 3A for standard lamps and other lighting. Appliances to be wired in have literature indicating the fuse rating used with them. Food mixers and TV sets, for example, generally use 3A fuses.
TVs and amplifiers usually have their own fuses as well. Amplifier fuses can blow if speakers are short circuited. Also they blow because of switch-on surge. If an amplifier is fitted with anti-surge or slow-blow fuses then they must be replaced with the same type. If the correct fuse is not used to replace a blown one, then it may not adequately protect an amplifier.
