What is typically assessed by the demand factor in residential electrical installations?

• A. The total potential amp draw
• B. Future load predictions
• C. User behavior patterns
• D. Total wattage installed

Answer: (A)

The demand factor in residential electrical installations is a measure used to assess the total potential amp draw that a system can expect during its peak usage time. This factor takes into account how much of the electrical capacity will actually be used at any given time, rather than simply the maximum possible usage if every appliance were to run simultaneously. By using the demand factor, electricians can better design systems that are both efficient and cost-effective, as it helps them understand and estimate the actual expected load rather than just the theoretical maximum. This plays a crucial role in ensuring that the electrical system can handle the common peak loads without being overbuilt, which can lead to unnecessary costs and energy waste. Other options may relate to aspects of electrical design but do not fundamentally represent what the demand factor is intended to assess. Future load predictions and user behavior patterns focus on forecasting and understanding usage trends, while total wattage installed refers to the sum of all connected devices without considering their usage patterns over time.
