After applying demand factors, what is the park electrical wiring system load for six mobile homes in a park?

To determine the electrical wiring system load for six mobile homes in a park, demand factors are applied, which take into account the fact that not all homes will use their maximum load at the same time. This is important since it allows for a more accurate estimation of the electrical demand.

The correct choice of 27,840 VA likely results from applying an appropriate demand factor to the sum of the individual loads associated with each mobile home. For instance, if each mobile home has a specified maximum load and utility demand factors are applied to reflect typical usage, the cumulative load for all six homes will yield a significantly lower figure than just summing their maximum potential loads.

To put this in context, the use of demand factors is a standard practice in electrical design, especially in residential and park settings, where peak demands can occur at different times. The calculated total will account for certain statistical probabilities of simultaneous use, effectively reducing the total demand, thus arriving at 27,840 VA as the system load for the six mobile homes when considering typical usage patterns.

Other choices would reflect either the sum of maximum loads without considering the demand factors or assume an unrealistic situation where all maximum loads are applied at once. Therefore, option B represents a realistic value for the expected load based
