How do circuit breaker keep the wires in a electrical circuit from overheating?

A circuit breaker is designed to 'break' in a circuit if a short circuit (or other malfunction) occurs. This prevents overheating (or burn-out) of the circuit wires. In older systems, you would need to find which fuse wire has fused and replace it. In a circuit breaker, once the fault has been found and corrected, the breaker is simply switched back on.

Can you upgrade a 15 Amps circuit breaker for a 40 Amp for a 8.5 Watt shower?

Not unless you change the wiring for that circuit. The breaker protects the wiring and if you install a 40 amp breaker on a 15 amp wire circuit you will have a fire in your home.

Should 25 amps breaker be replaced by 20 amps?

For typical residential house wiring 12 AWG wire is required for a 20 Amp breaker. If you change out the breaker for a 25 A breaker you would have to rewire the circuit with 10 AWG. In that case you could up the breaker to 30 Amps. All outlets and switches should be rated at the same voltage and current as the breaker.

Can you wire 10 Gauge and 12 Gauge in the same circuit?

Yes but there are two stipulations, one that the join or splice must be made in a junction box that is accessible and has a removable cover and the second stipulation is that the breaker that is supplying the power can not be larger that the smallest conductor. In this case no breaker larger that a 20 amp breaker as #12 wire is only rated at 20 amps..

Size fuse for 12 AWG wire?

Use a 20 amp fuse or breaker.

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.

What is a reusable circuit protector a circuit breaker - a fuse - a 10 gauge copper wire or a three prong outlet?

A reusable circuit protector would be a circuit breaker. It is designed to trip and be reset, whereas a fuse would need to be replaced once tripped. A 10 gauge copper wire and a three-prong outlet are components used in electrical systems but do not serve the same function as a circuit protector.

A circuit breaker is designed to 'break' in a circuit if a short circuit (or other malfunction) occurs. This prevents overheating (or burn-out) of the circuit wires. In older systems, you would need to find which fuse wire has fused and replace it. In a circuit breaker, once the fault has been found and corrected, the breaker is simply switched back on.

Give one advantage of using a circuit breaker rather than a wire or cartridge fuse?

An electrical breaker is dual function an electrical fuse just has one purpose.

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.

When installing a circuit breaker do you size the breaker to correct wire size or the device its controlling?

When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.

Can you upgrade a 15 Amps circuit breaker for a 40 Amp for a 8.5 Watt shower?

Not unless you change the wiring for that circuit. The breaker protects the wiring and if you install a 40 amp breaker on a 15 amp wire circuit you will have a fire in your home.

Your home has a fuse box at 15 amp is blowing can it be replaced with a 20 amp?

The only safe way to change your (fuse/breaker) would be to check your wire size and your load size. Fourteen guage wire is rated for a maximum capacity of 15 amps, if your wire size if 12 guage copper then the answer to your question is yes you can change your (fuse/breaker) to a 20amp. You should also call a qualified electrician to install your (fuse/breaker)

14 gauge wire can be on what size circuit breaker?

A 14 gauge wire is typically used on a 15 amp circuit breaker. It is not recommended to use a larger circuit breaker with a smaller wire size as this can create a fire hazard.

What device can break an electric circuit?

A switch or a circuit breaker can break an electric circuit by interrupting the flow of electricity. When the switch is turned off or the circuit breaker is tripped, the circuit breaks, stopping the flow of current.

What is the effect of changing the types of wire?

When ever a wire is changed, change it by the same type, rating or capacity of wire.

In electrical circuits what wire protects the operator?

Earth wire is meant to protect the user in case there is earth fault in the device or circuit. Only earth wire alone is not sufficient. It needs to be provided with suitable circuit breaker that breaks the circuit automatically.
