The short answer is No. If you replace a fuse with a piece of wire. The chances are you bypass the safety protection to over-current. A fuse works as a safeguard to an electrical circuit. It provides protection to electrical wiring harnesses and electrical components from damage. A fuse consists of a thin metal strip, which is designed to carry a limited amount of current. If the current exceeds its pre-determined current value, the metal strip will melt and stop the flow of current. This melting in one case is a good thing. It protects the entire circuit and electrical components from catching fire. If for example you replace a fuse with a piece of wire or rotate the wire to the blades of the fuse. There is a high chance that you will damage the protection of the circuit. This is because a piece of wire especially copper has a high melting point than the tin material used in the fuse’s metal strip. When a high amount of current flows through copper wire. It continues to heat up the circuit but will not melt the fuse. Whereas, it will cause a fire on the wiring harness. In conclusion, you should never go the other way replacing a fuse with a piece of wire or rotating the wire to the blades of the fuse. In one case, you can rotate the wire around the fuse is, in an emergency case. You can use the thinnest piece of wire, according to the amp, not a thick one, until you reach the workshop. Remember, it should be a temporary solution, not a permanent one. In one case, you can rotate the wire around the fuse is, in an emergency case.
