Yes, a 30 amp breaker is a 30 amp breaker. It must however be able to fit the box it is installed in.
No tandem breakers are of the same value.
If it is a 30 amp breaker then it is a 240 volt outlet.
You have a double pole breaker for 240Volt supply. The maximum current is 15 amp.
For typical residential house wiring 12 AWG wire is required for a 20 Amp breaker. If you change out the breaker for a 25 A breaker you would have to rewire the circuit with 10 AWG. In that case you could up the breaker to 30 Amps. All outlets and switches should be rated at the same voltage and current as the breaker.
No. The breaker must protect the circuit components such as wiring, outlets and switches that are connected to the breaker. Therefore if you have a 30 amp circuit as dictated by its components you need to protect it with a 30 amp or less breaker.
A 15 amp breaker is not sufficient for a 225 amp load. You would need a breaker that matches the load current, such as a 225 amp breaker. Using a 15 amp breaker for a 225 amp load would cause the breaker to trip immediately due to overcurrent.
Replace the 30 Amp Breaker with a 15 Amp breaker.
The breaker commonly used for ranges is a 40 amp. This size is used to cover the total wattage of the range. If for some reason all of the top elements and the oven were in use at the same time then the amperage drawn would be just under the trip setting of the breaker. If this same scenario were played out on the range with a 30 amp breaker supplying the power it would trip the breaker.
A 50 amp breaker is an overcurent device.
To replace a 20 amp breaker, first turn off the power to the circuit at the main electrical panel. Remove the panel cover and locate the 20 amp breaker. Carefully disconnect the wires from the old breaker and remove it from the panel. Install the new 20 amp breaker in the same position and reconnect the wires. Finally, replace the panel cover and restore power to the circuit.
No, you should not replace a 15 amp breaker with a 20 amp breaker without consulting a licensed electrician. The breaker size should match the wire size to prevent overheating and potential fire hazards.
Yes, but they obviously cannot be simultaneously loaded their maximum loads because the 400-amp breaker will blow well before that. Similarly, you can have multiple 100-amp panels fed from a 200-Amp main breaker, knowing that you will NEVER have 100 amps running in all panels at the same time.
