If you are using 14AWG wire in your circuit, you will fuse with a 15 amp breaker as 14AWG maximum amperage is 15 amps to 100 ft of wire. If the wire run is longer than 100ft, then you would fuse for 10 amps max.
If you are using 12AWG then it can carry 20 amps, etc. Longer than 100ft you would fuse for 15amps. note: 14AWG is called 14/2 and 12Awg is called 12/2 commonly.
The sizing of circuit breakers is dependent on the wire size going to the load. A #14 wire is protected by a 15 amp breaker. #12 a 20 amp breaker, #10 a 30 amp breaker, #8 a 40 amp breaker and #6 a 60 amp breaker. These are the most common breakers found in home electrical panels. On motor loads the breaker is sized to 2.5 times the full load amps of the motor. If it is not a standard breaker size then the next size up.
To answer this question a voltage value must be given. Circuit breakers protect the conductors that feed the load. The lower the voltage value, the higher the current value, hence a larger the wire size is needed and therefore larger the breaker size for the circuit. In reverse the higher the voltage value, the lower the current value, hence a smaller the wire size can be used therefore smaller the breaker size for the circuit.
Yes, the total current delivered to multiple devices in parallel is the sum of the individual branch currents (the vector sum if there is inductive load). Circuit breakers are resettable automatic switches that help protect against circuit overload (such as running too many hair driers and heaters on at one time) and faults (such as dropping the hair drier into a bathtub). Circuit breakers "operate" (or open) to stop current flow to the fault or overloaded circuit.
Switches, fuses and circuit breakers are examples of some of the electrical parts which can connect or disconnect a circuit to a source of current. A diode does it for alternating current, but only for one half of each cycle. "Connecting" allows an electric current to flow through the circuit. "Disconnecting" stops an electric current from flowing through the circuit.
60898 is an IEC standard; there are two parts. 1 is for AC, 2 is for DC. IEC 60898-1 "applies to a.c. air-break circuit-breakers for operation at 50 Hz or 60 Hz, having a rated voltage not exceeding 440 V (between phases), a rated current not exceeding 125 A and a rated short-circuit capacity not exceeding 25000 A." IEC 60898-2 "gives additional requirements for single- and two-pole circuit-breakers suitable for operation with direct current, having a rated d.c. voltage not exceeding 220 V for single-pole and 440 V for two-pole circuit-breakers, a rated current not exceeding 125 A and a rated d.c. short-circuit capacity not exceeding 10000 A. This Part 2 is to be used in conjunction with IEC 60898-1." (quotes taken from IEC abstracts)
For the US, the two common values are 15 and 20 amps, with 20 being the most common in newer homes and 15 more common in older homes. Which one is used is determined by what size of wiring is run. 15A breakers feed 14 AWG wire, and 20A breakers must use 12 AWG or larger. If you simply replace a 15A breaker with a 20, you will create a fire hazard.
Transformer voltage regulation and size of the circuit breakers have no direct relation
The purpose of the SEC's circuit breakers rule is to:
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.
most circuit breakers are under the hood near the battery. major breakers. you have to unscrew cover.
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.
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.
3 pole circuit breakers are used for 3 phase lines

Yes, different amperage rating circuit breakers can have the same short circuit characteristics.
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.
