What statement accurately describes the term "'continuous load"?

Question

Options

• AA load left on for 3 consecutive hours or more
• BA load supported by a direct feed from the utility
• CA load that supports a continuous run of 208 V cables
• DA load that consists of components that support both AC and DC power

• A
  84% (47)
• B
  4% (2)
• C
  9% (5)
• D
  4% (2)

Explanation

Option A is correct because the National Electrical Code (NEC) defines a continuous load as one where the maximum current is expected to continue for three or more consecutive hours - this definition drives key wiring and breaker sizing rules (conductors and overcurrent devices must be rated at 125% of continuous load current). Option B is wrong because how a load is fed (utility vs. generator) has no bearing on whether it is continuous. Option C is wrong because there is no such thing as a "continuous run of 208 V cables" as a defined load type - voltage and wire runs are separate concepts. Option D is wrong because AC/DC compatibility is a property of equipment design, not a definition of load duration.

Memory tip: Think of "continuous" the way you would a long meeting - three hours or more means it qualifies. The number 3 is the key: three consecutive hours makes a load continuous.
