Answer: If a fuse is not is not inserted in household electric wiring, the fault current flowing in the defective circuit will cause heating and potentially cause a fire before the upstream protection opens the circuit.
Why is a fuse used in electrical appliances?
The fuse breaks the circuit if a fault in an appliance causes too much current to flow. This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily.
Can I use an appliance without a fuse?
While most of us know that without a fuse, a household plug, and whichever appliance it’s attached to, won’t work. … A plug fuse is a safety device which is connected into an electrical circuit to prevent excessive current flow during fault conditions.
What is an electric fuse what is its importance?
In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current.
How does fuse wire protect an electric circuit?
A fuse is used in live wire to prevent short circuits. The fuse wire gets heated up and it melts and creates a gap in the live wire and current cannot flow through it and the appliance is saved from being damaged.
What appliances have fuses?
Plugs for appliances rated between about 700 watts and 3000 watts (the maximum rating of a wall socket) should be fitted with a 13-amp fuse (coloured brown). For example: 13A Fuse – Washing machine, dishwasher, microwave, kettle, toaster, iron.
How do fuses work in domestic appliances?
The fuse breaks the circuit if a fault in an appliance causes too much current to flow. This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily. If the current going through the fuse is too great, the wire heats up until it melts and breaks the circuit.
What fuse to use?
If it’s a rewireable type plug and the original fuse size fitted by the manufacturer is not known, the recommended method is to use the 700W rule: For an appliance rated as 700W or less, a 3A fuse should be fitted. For appliances above 700W, a 13A fuse should be fitted.
What is the disadvantage of using fuses?
It is not suitable for overload, at that time fuse blow off replacing of fuse takes time. During this period of lost power. The protection of fuse is not reliable.
What is fuse and its advantages and disadvantages?
Fuse is cheapest type of protection in an electrical circuit. Fuse needs zero maintenance. Operation of fuse is simple and no complexity is involved. Fuse has the ability to interrupt enormous short circuit current without producing noise, flame, gas or smoke.
Should every appliance has a fuse wire?
Answer Expert Verified
as the fuse help in the break off of circuit. … then if the high voltage is passes through it then the fuse wire get melt and cut off the circuit, Hance, the electricity of full house will be interrupted. but if every appliances every appliances then, the interruption may be reduced.
What might happen if the fuse is not inserted in a household wiring?
If a fuse is not is not inserted in household electric wiring, the fault current flowing in the defective circuit will cause heating and potentially cause a fire before the upstream protection opens the circuit.
How does electric fuse help in preventing from fires and damage to electric appliances?
Here is your answer: When excess current flows through a circuit, the fuse wire melts and breaks off. By this, fuse prevents damage to electrical appliances.
