To answer this question a voltage needs to be stated and whether the load is three phase or single phase. Without the voltage the amperage can not be calculated. For single phase, Amps = kva x 1000/voltage, for three phase, Amps = kva x 1000/1.73 x voltage.
No.
The proper ampere rating of a circuit breaker for an electric arc welder depends on the arc welder. Each is different. Look at the nameplate on the arc welder and choose the circuit breaker and wiring accordingly.
The ampere frame rating for a circuit breaker designates how the circuit breaker should be configured. It also states the trip unit of the amp.
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."
The maximum rating or a VCB is 32 KV.The maximum curent rating is up to 3000 A.
The maximum current rating for the circuit breaker needed for a 60 amp electrical load is 60 amps.
The maximum current rating for the circuit breaker needed for a device that operates at 20 amps is 25 amps.
Circuit breaker labels should include the voltage rating, current rating, type of circuit, and the location of the circuit breaker.
The maximum current rating for the circuit breaker is 150 amps.
The maximum current rating for a 15 amp circuit breaker is 15 amps.
The maximum current rating for a 30 amp circuit breaker is 30 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 amperage rating for a circuit breaker that can safely protect a 20 amp circuit is 20 amps.
No.
The maximum current rating for the circuit breaker required for a 125 amp load is 125 amps.
The maximum current rating for the circuit breaker that can handle a load of 40 amps is 40 amps.
The recommended amperage for a circuit protected by a 50-amp breaker is 80 of the breaker's rating, which is 40 amps.
