What is the rating of 2 20 amp breakers tied together?

When two 20-amp breakers are tied together, they are typically used in a configuration known as a double-pole breaker. This setup allows for a combined rating of 40 amps for the two-pole circuit, as each breaker can handle 20 amps individually. However, it's essential to ensure that the wiring and devices on the circuit are rated to handle the combined load safely. Always consult the National Electrical Code (NEC) and a qualified electrician for specific applications and safety guidelines.
