What will happen if a thick copper wire is used in fuse?
If a thick copper wire is used in a fuse then by definition of a fuse this device would no longer be defined as a fuse. A fuse in a circuit is used to protect the conductors feeding the load of that circuit. The circuit, if using a thick copper wire in a fuse, would then be considered as a non fused circuit.
What happen if fuse is connected to neutral wire?
The fuse will be blown off in case of any fault. But the circuit will not be isolated because of the presence of fuse in nutral line. current will still flow and the line will be so dangerous.
What number wire gauge for a single pole light switch?
In residential wiring applications the most used is 14 gauge wire for light switches as long as the circuit breaker or the fuse is 15A. If your lighting circuit is on a 20A fuse/circuit breaker then you need to use 12 gauge wire
How does a fuse break?
A fuse is a piece of wire that has a lower current rating than the rest of the circuit. When power is applied to a wire, it heats up (which is why electrical items get hot with use). The fuse wire melts at a lower temperature than the rest of the circuit - meaning that it breaks before the device is damaged by high current.
Why fuse wires are not used in a circuit containing electric circuit?
The size and composition of fuse wire is designed to "burn through" in an over current situation. That works fine as long as the current is lower than the fused rating. If you were to use the wire in the circuit then all your wire would essentially disintegrate in an over current situation.
How do you change wire fuse for circuit breaker?
A circuit breaker does not have a wire fuse in it.
Does subwoofer have fuse?
No the subwoofer itself does not contain a fuse. The Amplifier Connected to the sub should consist of a fuse or the power wire leading to the amp should contain one.
What is fuse what is it made up of?
A fuse in its simplest form - is simply a short piece of wire that is weaker than the circuit it is protecting. When the current flowing through the circuit exceeds the fuse rating, the fuse wire melts - breaking the circuit.

Why does the wire from the fuse box to the head light switch burn up?
Check the headlight fuse that's INSIDE the box. If an oversized fuse has been put in the fusebox you will have problems with the wire overheating whenever there is a problem in the circuit. There is a short circuit (wire touching chassis ground) somewhere in the lighting circuit, but the wire is burning because an oversized fuse has been put in the circuit.
How does circuit breaker or fuse protect the house from fire?
The fuse is matched to the size wire in the circuit the breaker/fuse it is protecting. For instance, a 20 amp breaker/fuse is used in combination with AWG 12/2 wire. A 15 amp breaker/fuse would be used with AWG 14/2 wire. If there is too much current flow in the circuit caused by either overloading the circuit or by a short in the wires the wiring would overheat and catch fire if not for the breaker/fuse. The breaker/fuse is designed to detect this and to trip or blow and shut off all power flowing to that circuit and prevent a fire. This is why you should never install the wrong size fuse. Put a 20 amp fuse on a 15 amp circuit and it would not protect the circuit as it should.
Why the fuse wire necessary in a circuit?
It is a safety device. It is not an essential part of the circuit.
What is an electrical fuse used for?
It's a safety device put in almost all electrical appliances and in all electrical systems (such as your house, and car). Should there be a power-surge or a short-circuit somewhere in the appliance or system the fuse will "blow" breaking the circuit and stopping the flow of electricity. this is done by having the centre of the fuse contain a wire which can only allow a certain amount of current through, if this current is exceeded, the wire will burn away/melt.
What is caused when the hot wire and either the neutral or ground wire make contact?
A short circuit. If things are working as they should breaker will trip or fuse will blow.
What happen if fuse is connected to neutral wire?
The fuse will be blown off in case of any fault. But the circuit will not be isolated because of the presence of fuse in nutral line. current will still flow and the line will be so dangerous.
Why is it not okay to use a fuse with a higher amperage rating in an electrical circuit?
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. A fuse of a higher rating than what is called for will allow a higher current to flow through the circuit which could cause the insulation on the wire to melt, the wire to burn open or components in the circuit to become unusable. Never over fuse an electrical circuit with a larger amp rated fuse.
Which do you think melts faster the wires in a circuit or wire that make up a fuse?
The fuse wire is thinner and it's designed to melt faster.
