IRC Electrical Inspector Practice Exam 2025 - Free Electrical Inspector Practice Questions and Study Guide

A continuous load is defined by its operational characteristics, specifically in how it draws electrical current over time. The concept of a continuous load refers to any load that consistently draws the maximum current for a duration of three hours or more. This is significant because it affects how electrical systems are designed and managed, especially in terms of ensuring that circuits and wiring can handle sustained current over long periods without overheating or becoming inefficient.

Choosing the option that identifies a load consistently drawing maximum current for three hours or more directly aligns with the standard definitions found in electrical codes and practices. These guidelines are crucial for ensuring safe operation, particularly in residential and commercial settings, where understanding load dynamics informs both installation practices and subsequent inspections.

In contrast, the other options describe different types of loads but do not accurately define a continuous load. For instance, intermittent loads (mentioned in the first choice) suggest that the load does not run continuously enough to meet the three-hour criterion, while loads that are only active during peak times refer to usage patterns rather than consistent current draw. Lastly, a permanently connected load that does not fluctuate might either represent a continuous load or could imply a steady load that doesn't draw maximum current consistently, which doesn't fit the definition of a continuous load as clearly as the chosen answer.
