The recommended load for a 30 amp breaker is typically 24 amps, which allows for a 20% safety margin to prevent overheating and ensure safe operation. This is based on the National Electrical Code (NEC), which advises that continuous loads should not exceed 80% of the breaker's capacity. Therefore, for short-term or non-continuous loads, a 30 amp breaker can handle up to its full rating of 30 amps, but it's best to stay within the recommended limits for safety.

What is the max load on a 30 amp breaker?
The maximum load on a 30 amp breaker is 30 amps at 40 degrees C. If the ambient temperature is higher that 40 degrees C then the breaker will trip at a lower current. Keep in mind the breaker is a dual function device. On a short circuit the magnetic component will trip the breaker instantaneously. If you are designing a branch circuit for a load that is constantly on, code may require you to "derate" the branch by 20 percent so that the ordinary load is not at the rated load of the overcurrent protection.
What is the difference between a 30 amp and a 40 amp breaker?
A 30 amp breaker is designed to handle a maximum continuous load of 30 amps, while a 40 amp breaker can handle a maximum continuous load of 40 amps. The 40 amp breaker allows for more current to flow through before tripping, making it suitable for higher power requirements compared to the 30 amp breaker. Always consult with a qualified electrician before adjusting or replacing circuit breakers to ensure safety and compliance with electrical codes.
What is breaker size for 240 volt 9 KW?
The formula you are looking for is I = W/E.
What happens when you plug a 30 amp appliance into a 50 amp breaker?
The appliance works perfectly. If you did it the other way around (50amps on a 30amp breaker, you would be tripping the breaker. Think of it as a mercury thermometer. The circuit breaker is the maximum temperature and the load on that breaker is the mercury. If the load is lower than the max, everything works beautifully. If the load becomes greater than the maximum rating, then things starting popping.
Is a 40 amp circuit breaker ok for a 30 amp air conditioner?
No, it is not recommended to have a circuit breaker with a higher amperage rating than the device it is protecting. In this case, you should use a 30 amp circuit breaker for a 30 amp air conditioner to ensure proper protection from overcurrent.

What is a 30 amp circuit breaker used for?
A 30 amp circuit breaker is needed unless the load is a motor circuit, then it has to be sized to 250 percent of the motors full load amps. For 30A circuit is needed breaker 30*1.25=37.5 --> 40A. If load is lamp or heater, then use breaker of group A or B. If load is motor, then use breaker of groupC or D (very hard start) or special safe breaker for motor - with variable amp setpoint. See related link also. By code you are only allowed 80% of the rating of a breaker. So 30x80%=24amps. 24 amps is the MAX allowed on a 30 amp breaker. You would need a 40amp breaker for a 30 amp circuit. 40x80%=32. So you would want a double pole 40amp breaker.
