* Circuit Breakers are Single-Pole or Double-Pole: Circuit breakers are designed to protect a single circuit (single-pole) or two circuits (double-pole). A double-pole breaker would have two "handles" that trip together, typically used for 240-volt circuits.
* Amperage Rating: Each individual pole of a breaker has its own amperage rating. So, you wouldn't have one breaker with two different amperage ratings.
What you might be thinking of:
* Two Separate Breakers: You could have two separate breakers, one rated at 20 amps and another rated at 30 amps. These would be installed in the electrical panel individually.
* Tandem Breakers: Some panels have tandem breakers, where two breakers share a single space. While they appear as one unit, they are still two separate breakers. You might have a tandem breaker with a 20-amp and a 15-amp rating, but not 20 and 30.
* A Special Circuit: If this is for a specific appliance or application, it's possible that you need a custom-designed breaker. However, this would be uncommon.
Important Note: It's crucial to work with a licensed electrician for any electrical work. They can determine the correct type and size of breakers for your specific needs.
