The maximum current rating for the circuit breaker should be at least 30 amps to accommodate the continuous current of 25 amps required by the load.
For a continuous load the circuit breaker is set 25% higher than the load current. So a 20-amp breaker is used with a continuous 16-amp load.
Depends on what you have connected to the circuit. It is less than 10 amps or the breaker would trip. A rule of thumb is you design for about 80% load related to the breaker. For 20 amps that would equal 16 amps.
A circuit breaker does not give off amperage. A circuit breaker allows a flow of current up to the rating of the breaker. Any current higher than that of the breaker's rating will open the breaker's contacts and stop the flow of current.
the maximum short current that can be safely break by the circuit breaker.
The maximum current rating for the circuit breaker is 150 amps.
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."
200. Although you cannot exceed current ratings on any branch circuit without tripping that circuit. You need to make sure that you do not exceed 160 continuous load amps to meet NEC requirements of not overloading a breaker to more than 80% under continuous load.
Circuit breaker labels should include the voltage rating, current rating, type of circuit, and the location of the circuit breaker.
No, a circuit breaker is a safety device that is used in a circuit to limit the amount of current in an overload or short circuit condition. The number on a breaker is the top end current that the breaker will handle before opening the circuit.
The maximum current rating for a 15 amp circuit breaker is 15 amps.
The maximum current capacity of a 100 amp circuit breaker is 100 amps.
The maximum current capacity of an 80 amp circuit breaker is 80 amps.
