If by circuit breakers you mean fuses the answer is yes they do. The 03 Passat fuse box is located behind a panel on the drivers side where the dash board meets the door. You have to open the drivers door to see it. Pry the panel out by the front edge facing you and it will pop out revealing the small multi colored fuses.
Homes should have circuit breakers so that you can slow down voltage in electronics.
Lowes and Home Depot carry circuit breakers as well as the wiring and box. Circuit Breakers come in several watts, so be sure you get what is appropriate for your living space.
You don't specify whether you mean low-voltage circuit breakers, such as MCBs (miniature circuit breakers) or high-voltage circuit breakers. In either case, repeated tripping under fault conditions causes arcing which damages the main contacts of the circuit breakers. For this reason, high-voltage circuit breakers are taken out of service after a specified number of tripping operations, so that the contacts can be maintained or, if necessary, replaced. MCB contacts are inaccessible, and the MCB may eventually require replacing.
They are in series with the load so that if tripped no current will flow to any connected device.
It depends what circuit you are making.Circuit breakers come in different 'ratings' and so are chosen according to the power demands of the circuit you have.You don't choose a circuit for a circuit breaker as such, you choose a circuit breaker according to what circuit you have made.
That depends on what you're calling "piggy back". Most manufacturers provide a breaker category that allow two circuit breakers to fit into what would normally be the space for one. Breakers should NEVER be connected such that the output is tied together to provide for greater current output, so if that's your definition of piggy back, the answer is "no".
Fuses and circuit breakers are designed to open a circuit when an excess amount of current occurs, so as to break that flow of current.A circuit breaker or fuse.
He may have installed Tandem breakers. Tandem breakers allow you to fit 2 breakers into one standard breaker slot. They are slimmer in design to allow for this.
Presumably, you are describing the spring-charging mechanism on high-voltage circuit breakers? If so, then the reason is because, in the event of an electrical fault in which the substations loses its a.c. supply, the circuit breakers can be recharged from the standby d.c. batteries.
we can use air at wide range owing it is so economic,,,,,no polution leave after operation,.
When a thunder falls on a sub station, immediately a high voltage is produced in the bus bars connected to the substations. This high voltage is sensed by the relays & they send signals to circuit breakers, due to automatic system circuit breakers they are opened immediately. After clearing the faults the breakers closes automatically. so that sub stations are free of damages.
You can't change the one breaker, but you can't use two separate arc fault breakers unless you separate the neutrals. However double pole arc fault breakers are made for this purpose and the common neutral would be O.K.
Circuit breakers are overcurrent protective devices, so must be capable of interrupting a fault current, and closing onto a fault, without damage to the circuit breaker. Circuit breakers are also used to interrupt load currents. Isolators are generally designed to disconnect circuits on 'no load' -that is when there is no current is flowing through the circuit; their function is simply to provided a physical break between the load and the supply once the circuit has been interrupted by a load-breaking device such as a circuit breaker.
A parallel circuit is used in a strand of Christmas lights so that if one bulb goes out, the rest don't. A parallel circuit is also used in circuit breakers of houses. A series circuit is used in a flashlight. Everything follows one path.
Because the amount of heating depends on how much current is in the wires. So you set the CB to cut the current if it exceeds the rated current for that wire.
To protect the system from faults the equipment used is known as switch gearAnswerSwitchgear is the generic name for transmission and distribution equipment designed control, disconnect, and protect an electrical system. Switchgear includes circuit breakers, fuses, and isolators (US term: disconnectors). As well as being used to control circuits by opening or closing those circuits, circuit breakers are designed to interruptand to close onto electrical faults so must incorporate means of extinguishing the arcing associated with such faults. Circuit breakers, therefore, have a essential role in responding to protection systems. Isolators are non-load breaking switches, designed to isolate equipment (including circuit breakers) from high voltages, so that the equipment can be maintained.
a method of interconnecting several circuits and breakers in a switchyard so that three circuit breakers can provide dual switching to each of two circuits by having the circuits share one of the breakers, thus a breaker and one-half per circuit; this scheme provides reliability and operating flexibility, and is generally used at 500 kV when more than five lines terminate in a substation.
Fuses and circuit breakers are meant to protect your home's wiring from the heat generated from fault-currents and over-currents. Over-currents happen when you exceed the amperage the fuse or breaker is rated for over a period of time (IE: drawing 20 amps on a 15 amp circuit breaker). When this occurs a fuse or circuit breaker will open the circuit so the wiring in your home will not be damaged. Over-currents happen when electricity finds a path, other than the one intended, to ground. When this happens there is very little resistance to slow the flow of electricity and the amperage through the circuit can exceed the fuse or circuit breakers rated capacity by several hundred times . These type of faults cause the fuse or circuit breaker to open the circuit very quickly.
All Circuit Breakers have a current rating and a FAULT current rating. The current rating refers to the current at which the circuit breaker is designed to 'break' the circuit and this is generally shown in Amperes (A). FAULT current rating is generally alot higher rating and is therefor shown in kilo Amperes (kA). This kA rating refers to the amount of current which a circuit breaker is designed to handle under fault conditions and can still maintain operation and 'break' contact. Most household circuit breakers are around 7.5 kA, so any fault over 7,500 Amperes could potentially damage the circuit breaker contacts to the point which it can not open the circuit. Larger fault ratings are found in larger applications such as MCC's on plants, minesites or power stations.
The previous answer is incorrect, and I would advise that user to not give out information if they are going to give completely misguided information. The interrupting rating of a breaker is the maximum current that the breaker is designed to handle, at the breaker's rated voltage, before damage will occur to the breaker. A breaker will trip at FAR LESS than the interrupting rating, but it is extremely dangerous to expose the breaker to any situation where it will have more than the rated interruption current. the breaker is designed for. The reason some breakers are rated at 22kA instead of 10kA is because they typically have far larger conductors hooked up to them, so with the lowered impedance on the circuit there is more of a chance for the breaker to experience a higher fault current at the breaker. So electricians install 22kA breakers to handle the higher "available fault current."
Tandem breakers, often called split breakers or double breakers, provide two separate circuits in the space of a regular sized breaker opening. Every circuit breaker panel has a limited number of circuit openings available. The problem is that when the openings are all used up and you still need to add another circuit, what do you do? You could change the electrical panel or double up circuits on a breaker, but this could place too much load on a particular circuit. So what then? The answer that many have found is a tandem breaker. This type breaker is the same size as any other breaker, but it has its difference. This breaker sports two smaller breakers built into one regular sized breaker. Each has its own breaker switch and the breaker snaps in just like a regular breaker. With this simple innovation, you can add a circuit and protect the circuit on its own dedicated line.
'Electricity' is not a quanitity, so you cannot have 'too much' or 'too little' electricity! On the other hand, if a load draws too much current, then it may cause a circuit breaker to open. Circuit breakers are 'overcurrent' protection devices, which will operate in the event of an overload current or a short-circuit current.
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.
Each color identifies the amp rating, yellow=20 amp, blue=15 amp and so on.
There are many examples of precautionary measure about electricity. Use of fuses, circuit breakers, insulators and so on is a good example. There are many hazards that are associated with electricity.
