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?
If you plug a 30 amp appliance into a 50 amp breaker, the breaker will still function to protect the circuit from overheating due to excess current. However, the appliance may not draw enough current to trip the breaker in case of a fault, potentially causing damage to the appliance. It is generally recommended to match the amperage of the appliance to the appropriate breaker size.
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 the recommended amperage for an RV breaker, specifically for a 30 amp RV breaker?
The recommended amperage for a 30 amp RV breaker is 30 amps.
What is the recommended amperage for a breaker to use with a 30 amp dryer?
The recommended amperage for a breaker to use with a 30 amp dryer is 30 amps.
What is the recommended wire size for a 30 amp breaker?
The recommended wire size for a 30 amp breaker is typically 10 gauge wire.
What is the recommended amperage for a 30 amp RV circuit breaker panel?
The recommended amperage for a 30 amp RV circuit breaker panel is 30 amps.
What is the maximum electrical load that can be safely handled by a 15 amp 2 pole breaker?
The maximum electrical load that can be safely handled by a 15 amp 2 pole breaker is 30 amps.
What is the maximum electrical load that can be safely handled by a 15 amp breaker 2-pole?
The maximum electrical load that can be safely handled by a 15 amp 2-pole breaker is 30 amps.

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.
How do you turn a 30 amp circuit into a 15 amp cicuit?
Replace the 30 Amp Breaker with a 15 Amp breaker.
