Why does fuse wire burn and what is advisable?
Understanding Fuse Wire Burning
When a heater is turned on, the fuse wire repeatedly gets burnt even after changing the same fuse wire with the same length and width. This happens because all of the circuit's current flows through the fuse wire, which is a metal ribbon inside the fuse. The fuse wire is designed to allow a specific amount of current to pass through it. However, if the current exceeds this capacity, the wire heats up, melts, and opens the circuit, protecting the rest of the electrical system from damage.
Advisable Actions
What is advisable to prevent fuse wire burning?It is advisable to check the current rating of the fuse wire and ensure that it matches the current flowing through the circuit. If the current is consistently higher than the fuse wire's capacity, a larger or higher-rated fuse should be used to prevent burning. Additionally, checking for any short circuits or overloads in the electrical system can help prevent excessive current and protect the fuse wire from burning out.
In conclusion, the fuse wire burns when too much current flows through it, causing it to overheat and melt. By ensuring that the fuse wire's current rating matches the circuit's requirements and taking preventive measures against overloads, the risk of fuse wire burning can be minimized.
