When calculating service load, which of two noncoincident loads needs to be included?

• A. smaller
• B. equal
• C. larger
• D. none

Answer: (C)

When calculating service load, the larger of two noncoincident loads needs to be included because this reflects a more accurate representation of the maximum potential demand on the electrical system. Noncoincident loads are defined as loads that do not occur at the same time; hence, their peak demands may happen during different periods. Since only the maximum demand needs to be accounted for in situations of noncoincidence, using the larger load ensures that the system can handle the highest level of demand that could potentially occur at any time, which is critical for safety and reliability. Selecting the larger load helps in ensuring that the system is adequately sized and prevents issues such as overloads or failures that could arise if only the smaller load were considered. This approach is in line with electrical codes and standard practices, which prioritize safety and system efficiency.
