It is a power safety move. When you are heating your home in the winter time and maybe the heat gets turned up on a very cold day, the temperature could go higher that where the set-point for cooling is set on the air conditioner. The two devices would be in conflict with each other. The heating system trying to warm the house and the A/C trying to cool the house both at the same time. With the breaker turned off to the A/C this will not happen and the house will heat up to where you set the heating thermostat. Most large commercial and industrial businesses have interlocks between the two systems so that only one system can work at a time.

What would happenif you put an 8 amp circuit-breaker in a power circuit?
The circuit would be protected up to 8 amps before the breaker would trip. Any more that 8 amps and the circuit would open and shut the circuit off.
Circuit breaker trip cause smoke will homeowner insurance pay for it?
A circuit breaker does not "cause" smoke. A circuit breaker "breaks" a circuit when there is too much current, creating a hazardous condition for the wires that are connected to the circuit breaker. The circuit breaker PROTECTS you from electrical fire. Find the source of the smoke; what burned? If a circuit breaker tripped during the incident, it is usually caused by melting/burning wire insulation, either inside or outside of an appliance. If the insulation inside the walls of your house has burned/melted, it could be that the circuit breaker was too large for the wire or that the circuit breaker failed to shut off at the appropriate current load. If the circuit breaker failed, your insurance should help you. If an appliance overloaded the circuit, your insurance should help you. If someone connected an oversized circuit breaker, causing the wire to overheat, your insurance company may refuse to help you.
Does the current still flow when the circuit has blown?
If everything is working as it should then no current flows when the breaker is off. This is no better example of this than there is on answers. When a do it yourselfer looks for an answer and gets one, the answer is always ended with the suggestion that before doing any work always shut off the breaker. If the breaker is malfunctioning one symptom is that a voltage is still present even though the handle is in the off position. If this is the case change the breaker out immediately.
Can you use two 15 amp single pole breakers in place of a double pole 30 amp breaker?
Yes. An everyday occurrence of this circuitry is in your kitchen counter split receptacles. The top half of the receptacle is a 15 amp circuit and from the same breaker the bottom half of the receptacle is another 15 amp circuit. A two pole single handle breaker is a common trip. If one of the circuits fed from the breaker faults the other connected circuit will shut off also. If you are talking about slot position in a breaker panel, you can remove the two pole breaker and install two single pole breakers.
What are the advantages of 3 pin plug?
The three prong plug incorporates a ground wire for safety. If there is a short circuit in an appliance that has a three prong plug, the current will travel back to the electrical panel and either blow the fuse to that circuit, or trip the circuit breaker to shut power down on that circuit.

Do you shut the water valve first or the hot water circuit breaker when going away for an extended vacation?
the hot water circuit beaker
Do you have a 15 0r 20 amp circuit?
Go to your distribution panel and shut off the breaker that you think is the circuit in question. If the circuit becomes de-energized then the breaker you just turned off feeds that circuit. Look on the handle of the breaker and the number you see is the amperage of that circuit. <<>> Determination of a 15 or 20 Ampere circuit is normally indicated by a combination of a 20A breaker and a 20A dedicated outlet. A 15A circuit normally has multiple outlets; not typical in a 20A circuit.
What is the latest technology in circuit breaker?
The latest technology used in circuit breakers are Arc Fault Circuit Interrupters. They will shut off the circuit if the hot and neutral or two hots touch.
What do you call a push button switch that you push on when power supply shut down you have to push it on again?
That would be a breaker, as in circuit breaker. Just like the ones on your house.
What devices shut down immediately if a short circuit occurs?
A circuit breaker shuts down and can be reset. (A fuse does not "shutdown", it fails, or blows, or breaks and cannot be reused.)
Purpose of a breaker in an electrical circuit?
Breakers ensure that when too much amperage is being drawn through the circuit the power is shut off. Excessive amperage creates heat. Without a breaker that heat buildup could lead to fire.
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.
Does the current still flow when the circuit has blown?
If everything is working as it should then no current flows when the breaker is off. This is no better example of this than there is on answers. When a do it yourselfer looks for an answer and gets one, the answer is always ended with the suggestion that before doing any work always shut off the breaker. If the breaker is malfunctioning one symptom is that a voltage is still present even though the handle is in the off position. If this is the case change the breaker out immediately.
How can you push 30 amp breaker to 50 amp?
Not if it's functioning properly. The purpose of a circuit breaker is to shut off power if the circuit exceeds the rated power capacity of the wires. Don't plan to exceed the 30 Amp capacity of your house wiring; the results will be destructive.
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.
