What Is The Purpose Of A Fuse In A Plug?

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.

Does the fuse in a plug matter?

The appliance itself is fused

and that is to help protect the appliance. The fuse in a mains lead just needs to be rated at less than the maximum current capacity of the cable. So if you're using 20 amp rated cable then a 13 amp fuse protects it.

What is the main function of fuse?

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.

What happens if you take a fuse out of a plug?

Without a fuse, a household plug, or any appliance that's attached to it,

it won't work

. A plug fuse is a safety device that is connected into an electrical circuit to prevent excessive current flow during fault conditions.

What is the purpose of fuse in a consumer unit and main plug?

The circuit will break if the current is too large. The flexible lead between the plug and the appliance can be protected with a fused lead. The main purpose of the fuse is

to prevent fires due to large currents

.

What are the advantages of a fuse?

• 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.

What are the 3 types of fuses?

• DC Fuses.
• AC Fuses.
• Cartridge Fuses.
• D – Type Cartridge Fuse.
• HRC (High Rupturing Capacity) Fuse or Link Type Cartridge Fuse.
• High Voltage Fuses.
• Automotive, Blade Type & Bolted Type Fuses.
• SMD Fuses (Surface Mount Fuse), Chip , Radial, and Lead Fuses.

Will a plug work 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.

Is it safe to use a plug without a fuse cover?

Without a fuse, a household plug, or any

appliance that's attached to it, it won't work

. … The plug fuse is thought of as an electrical safety valve which provides extra protection in addition to the main house fuse box or circuit breaker.

What fuse should be in a TV plug?

Plugs for appliances rated up to about 700 watts should have a 3-amp fuse (coloured red). For example:

3A Fuse

– Table lamp, standard lamp, television, video, computer, mixer, blender, fridge, freezer, power drill, jig saw, soldering iron.

How do you know if a plug fuse is blown?

Remove the fuse from its holder. In some cases you may need a small screwdriver to unscrew the fuse holder cap. Look at the fuse wire.

If there is a visible gap in the wire or a dark or metallic smear inside the glass

then the fuse is blown and needs to be replaced.

Who is responsible for the main fuse?

Your fuse delivers power into your home

The fuse carrier

is what holds your main electrical fuse and can sometimes have an outer fuse case. The company you pay your electricity bills to own your electricity meter, then you own the fuse box (sometimes called trip switches) inside your property.

What is the purpose of a plug?

How do you choose a fuse rating for a load?

In order to select the right amperage of the fuse, you first need to know the full-load steady-state current of the circuit at an ambient temperature of 25o C (68o F). Once the current value is determined, then a fuse rating should be selected as to be

135%

of this value (taken to the next standard value).
