Question: 1 / 140

For ranges rated at 8 ¾ kW or more, what is the minimum branch circuit requirement?

30 A

40 A

The minimum branch circuit requirement for ranges rated at 8 ¾ kW or more is indeed 40 A. This specification ensures that the circuit can handle the load associated with such high-power appliances, preventing overload conditions that can lead to tripped breakers or even electrical fires.

When a range pulls 8 ¾ kW, it can create a significant demand for current, especially during peak usage times, such as when multiple burners or the oven are in operation simultaneously. The National Electrical Code (NEC) provides guidelines for branch circuit requirements to ensure safety and efficiency in electrical installations. A 40 A circuit allows for adequate capacity considering factors like load diversity and potential inrush currents when heating elements are activated.

Understanding the context of why a range with this power rating needs a 40 A circuit highlights the importance of careful planning in electrical systems, ensuring devices operate within safe parameters.
