A continuous load is defined as a load where the maximum current is expected to continue for how long?

A continuous load is defined as a load where the maximum current is expected to continue for a duration of 3 hours or more. This definition is important in electrical design and safety considerations, particularly when sizing conductors and equipment.

When a load is classified as continuous, it helps engineers and electricians understand that the load will not only draw current consistently but may not allow for temporary fluctuations. The 3-hour specification ensures that installations can safely handle this sustained demand without overheating or risking failure.

Understanding this classification helps in adhering to the National Electrical Code (NEC), which takes the duration of the load into account during system calculations and the selection of appropriate protective devices to prevent hazards.
