Can you use two 15 amp single pole breakers in place of a double pole 30 amp breaker?

No, you cannot use two separate 15 amp single pole breakers in place of a double pole 30 amp breaker. A double pole breaker is designed to simultaneously disconnect both circuit conductors, whereas using two single pole breakers would not provide the necessary protection for the circuit. It is important to use the correct size and type of breaker as specified by the electrical code for safety and functionality.
