Which type of circuit may utilize a 30-amp breaker?

Utilizing a 30-amp breaker is appropriate for circuits with higher electrical demands, and electric range circuits fall into this category. Electric ranges require a significant amount of power to operate, typically ranging from 20 to 50 amps, depending on the model and features. A 30-amp breaker is commonly used to ensure that the circuit can handle the load safely without tripping under normal usage conditions.

It is important to understand that circuits such as bathroom circuits, air conditioning circuits, and low-voltage lighting circuits typically operate on lower amperage breakers. Bathroom circuits usually use 15 or 20-amp breakers, while air conditioning circuits vary but often use 20 or 30 amps depending on the unit size. Low-voltage lighting circuits are designed for low current and would not use a standard breaker, making the 30-amp requirement specific to electric range circuits. This illustrates the significance of matching the breaker size to the specific demand of the electrical load being supplied.
