The fuse is supposed to be the weakest link in the circuit. The circuit is rated to handle a specific load current. The wire and insulation rating of the circuit is governed by this specific load. If this load malfunctions and the load current becomes higher that what is specified, the fuse is there to break the circuit. Never over fuse an electrical circuit with a larger amp rated fuse.

What else can I help you with?
A fuse is not used for?
A fuse is not used for increasing electrical current. Fuses are designed to protect electrical circuits by breaking the circuit when there is an overload or short circuit, preventing damage to the circuit and potential fire hazards.
Why is it that every house supplied with electricity is provided with a box of fuses?
A box of fuses is used to protect electrical circuits from overloading and overheating, which can cause fires. Fuses act as a safety device by breaking the circuit if too much current flows through it. This helps prevent damage to appliances and wiring in the house.
Does sugar create electrical resistance?
Sugar is not used in electrical circuits.
Where would one use electrical connectors?
An electrical connector is a device used for joining electrical circuits. These connectors can be temporary or permanent. An electrical connector is also called a physical interface.
What is the name of an instrument for measuring electrical current?
A multimeter is a common instrument used to measure electrical current. It can measure current, voltage, and resistance in electrical circuits.
Can parallel circuits be used instead of fuses?
No. Parallel circuits are not fuses. Fuses can be used to protect parallel circuits.
A fuse is not used for?
A fuse is not used for increasing electrical current. Fuses are designed to protect electrical circuits by breaking the circuit when there is an overload or short circuit, preventing damage to the circuit and potential fire hazards.
What are 3 conductors used in your home?
Copper, aluminum, and silver are commonly used conductors in homes for electrical wiring and circuits.
Is it common for the hot wire to be used in electrical circuits?
Yes, it is common for the hot wire to be used in electrical circuits to carry the current from the power source to the electrical devices.
Why is it that every house supplied with electricity is provided with a box of fuses?
A box of fuses is used to protect electrical circuits from overloading and overheating, which can cause fires. Fuses act as a safety device by breaking the circuit if too much current flows through it. This helps prevent damage to appliances and wiring in the house.
What are the kinds of electric circuits?
In the electrical trade there are three types of electrical circuits. They are series, parallel and series - parallel. All three types are used every day in building construction and home construction.
Does sugar create electrical resistance?
Sugar is not used in electrical circuits.
Which electrode is typically used as a ground reference in electrical circuits?
The electrode typically used as a ground reference in electrical circuits is the earth ground electrode.
Which electrical unit is used to rate cartridge fuses?
Amperage is used to rate cartridge fuses.
What element is used in jewelry tableware electrical circuits and to coat glass?
Silver is used for all these. Gold could be, but silver is more likely to be used in electrical circuits and for mirrors.
What are the common fuses for household use?
In tht UK, common fuses used in the plugs are 3 amp, 5 amp and 13 amp. We have rather seperseded fuses at the main distribution points domestically by installing re-settable circuit breakers, and they have ratings between 6 amps and 80 amps depending on what the circuits are supplying.
Where are parallel circuits used?
Parallel circuits are used when there are many electronics on the same circuit, such as Christmas lights, for example. If they were on a series circuit, if one bulb went out all of them would go out. In your home, parallel circuits allow you to turn any electrical device on or off, independently of the others.
