Can you replace a 20 amp circuit breaker with a 25 amp circuit breaker?
No. The breaker must protect the circuit components such as wiring, outlets and switches that are connected to the breaker. Therefore if you have a 30 amp circuit as dictated by its components you need to protect it with a 30 amp or less breaker.
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 a 8 amp be changed to 15 amps on circuit breaker?
If you are asking if you can change an 8 Amp Circuit Breaker to 15 Amps, the answer is no. If there is an 8 A breaker in place it is sized to protect the wiring and devices on the circuit. Increasing to 15 A would defeat this protection and could cause a fire or cause a connected device to be destroyed with higher amperage.
How to bypass single phase circuit breaker?
You should never try to bypass any protection devices. This is just asking for trouble down the road. The circuit breaker is there to protect the wiring to the device that is powered from that breaker. If the load is too large and keeps tripping the breaker install a larger breaker with new wiring sized to the breaker to accommodate the higher load current. Again do not bypass circuit breakers as you will have no short circuit or overload protection.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliancesalways use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
How do you avoid overheating of the electrical wiring of the equipment?
Overheating of electrical wiring is overcome by installing the correct size conductors to carry the load amperage of the equipment. Use a larger size wire to the load. The main purpose of the breaker is to protect the wire that is connected to it. If the wire becomes overloaded due to a high current flow the breaker will trip.
What is the function of the fuse or circuit breaker in a circuit?
A circuit breaker/fuse is designed to protect the wiring from getting overloaded.

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.
What size amp circuit breaker would protect a 12kW boiler?
The breaker protects the wiring not the boiler. 12,000 watts at 240 volts will require 50 amps. So, you will need a 60 amp breaker using AWG# 6 wire on a dedicated circuit.
What do fuses and circuit breakers do?
Fuses and circuit breakers protect the conductors that are connected to them from not letting the current going above the current rating that is given to individual size conductors.the main function is to quickly stop the power to continue threw the loop., and to protect ,equipment from damage and people from dying, that may be in contact to a shorted circuitCommentFuses and circuit breakers are overload protection devices, designed to protect loads (e.g. appliances) against overload or short-circuit currents. They are not designed to protect people.to over come the over load conditions.In simple terms the purpose of a fuse or circuit breaker is to protect the wiring from overheating and causing a fire. That is why it is so very important to match the fuse or breaker with the size wire in the circuit.Protect the circuit from over current. Fuses and breakers prevent excessive amounts of current to flow through the conductors in a circuit which causes heat to build up making for a fire hazard.A circuit breaker or fuse is a protective device that shuts off power when the current exceeds a preset limit. It is designed to protect the wiring, and thus prevent damage to the equipment and fire.
Circuit breakers are used for what?
Circuit breakers prevent excessive current from flowing in the circuit by "tripping" when the current exceeds the circuit breaker rating. This causes the current to be cut off, and is used to protect the wiring as well as the appliances.
Can a 8 amp be changed to 15 amps on circuit breaker?
If you are asking if you can change an 8 Amp Circuit Breaker to 15 Amps, the answer is no. If there is an 8 A breaker in place it is sized to protect the wiring and devices on the circuit. Increasing to 15 A would defeat this protection and could cause a fire or cause a connected device to be destroyed with higher amperage.
How you select a circuitbreaker?
A circuit breaker is intended to protect the wiring of the circuit from overload. The larger a CB is, the faster it will operate, thus in a short circuit situation, the (say) 60Amp breaker will trip before the 30 amp one that is in series. You should only have a moderate factor of safety in your choice of CB. The wiring itself will have a recommended current rating and this is a guide as to the CB.

In the electrical circuit of a house the fuse is used?
A fuse/breaker is used to protect the wiring within the home for overheating and catching on fire. When the fuse/breaker detects an excess flow of current beyond the range of the fuse/breaker, within a circuit, it will blow/trip to shut off the flow of electricity in that circuit thus preventing a possible fire.
What is the safety feature in preventing overheating of wiring?
A circuit breaker, or a fuse.
