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.
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..
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.
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 number wire gauge for a single pole light switch?
For a single pole light switch, typically you would use 14-gauge wire which is commonly used for lighting circuits in residential settings. It's always a good idea to check your local electrical code requirements to ensure you are using the correct wire gauge.
What happens when you connect live wire to ground?
Connecting a live wire to ground can cause a short circuit. This can lead to a sudden surge of electricity flowing through the circuit and may result in a tripped circuit breaker or blown fuse, as well as potential damage to electrical equipment and a risk of fire. It can also pose a serious shock hazard to anyone in contact with the grounded object.
How do you tell if a wire is shorted out?
If a wire is shorted out, you may notice sparks, smoke, or a burning smell coming from the wire. You can also use a multimeter to test for continuity between the two ends of the wire - if there is continuity, it indicates a short circuit.
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.

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)
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.
