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.
Circuit breakers protect your home by stopping the flow of electricity if there is too much amperage draw. If there were no circuit breakers installed, then you could overload wires; when too much is plugged into a circuit, or the circuit shorts out, the wires can heat up very quickly and cause a fire. Circuit Breakers prevent this by disconnecting the circuit before the wires get hot enough to catch fire.
A circuit breaker sets a limit on the amount of amperage that can be applied to the circuit's conductor. This is why wires and breakers have amperage ratings. The wires ampacity is matched to the breakers ampacity. If there is a higher that normal amperage capacity, than what the wire is rated for, the breaker will trip the circuit open.
Homes should have circuit breakers so that you can slow down voltage in electronics.
A circuit breaker can be reset, and it responds faster.
Yes, different amperage rating circuit breakers can have the same short circuit characteristics.
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.

Circuit breakers do not have circuit diagrams. The breakers have an input where the distribution voltage is applied and an output where the load is applied. If you want to know what is inside a breaker, the electrical terminology to use is "shop drawings" of the specific breaker that you need information on.
1950's
During an electrical fault, be it a short circuit or circuit overload, fuses and breakers are designed to open at a specific amperage. This opening of either device eliminates a fire hazard before it gets a chance to start. This is how fuses and breakers protect the home.
It is recommended to use a circuit breaker with a rating of 15-20 amps for plugs and geysers in residential homes. However, it is important to consult an electrician to determine the appropriate circuit breaker size based on the specific electrical load requirements of your plugs and geysers.
From the beginning of electricaly wired homes (aprx. 1880) until about the late 50's or early 60's. They were replaced with circuit breakers because circuit breakers will trip a lot faster when a short occurs and can be re-used as apposed to having to be thrown out and replaced after a short.
No. Plugs, lamps and 220 V a.c. items are in parallel with the breakers.CorrectionAll loads are in parallel with the supply voltage, but in series with the circuit breakers or fuses.

Square D circuit breakers can be purchased from various homeware and DIY stores such as Home Depot or Lowes. Websites that specialise in circuit breakers such as Circuit Breaker Service or All Breakers do sell them as well.
GE circuit breakers with catalog numbers ranging from THQL1115 through to THQL1150 can be substituted like for like with Cutler-Hammer circuit breakers coded CL115 through to CL150, ITE Siemens circuit breakers coded Q115 through to Q150 and Square D circuit breakers coded HOM115 through to HOM150. These are single pole breakers. GE circuit breakers with catalog codes from THQL2115 through to THQL2150 can be substituted with Cutler-Hammer circuit breakers CL215 through to CL250, Square D circuit breakers HOM215 through to HOM250 and ITE Siemens circuit breakers Q215 through to Q250 of the same amperage and voltage. These are double pole breakers.
most circuit breakers are under the hood near the battery. major breakers. you have to unscrew cover.
Certainly not in the case of high-voltage circuit breakers. Probably not in low-voltage circuit breakers, as copper is a better conductor and has a higher melting point.
