What defines a "dedicated circuit"?

A dedicated circuit is specifically designed for a single appliance or device, ensuring that it receives a consistent and uninterrupted power supply. This type of circuit is essential for high-power devices or appliances, such as refrigerators, air conditioning units, or industrial equipment, which may require more power than general circuits can safely handle. By servicing only one device, dedicated circuits help to prevent overload situations and reduce the risk of electrical hazards, such as tripped breakers or electrical fires.

In contrast, circuits that are shared by multiple devices can lead to issues with voltage drops and potential overloads if too many devices are drawing power simultaneously. Heavy-duty circuits or those designed to handle multiple loads may not necessarily be dedicated to one device, which does not align with the defining characteristics of a dedicated circuit.
