What is the typical method for calculating residential service size?

The method commonly used for calculating residential service size is the Service Selection method. This approach takes into account various factors unique to residential settings, focusing on the anticipated electrical demand of the household, which includes lighting, appliances, and other devices that will significantly affect service requirements.

The Service Selection method is advantageous as it allows for adjustments based on the specific characteristics of the residence, including the number of occupants, types of appliances, and usage patterns. This tailored approach helps ensure that the service size is adequate to meet the actual load without being oversized, which can lead to unnecessary costs.

In contrast, other methods like the Demand Factor method, while useful in assessing load requirements, may not be as directly applicable to unique residential scenarios where personal usage factors play a significant role. Similarly, the Load Average and Maximum Load methods tend to provide more generalized data or peak demand scenarios that might not accurately reflect everyday usage in a household, making the Service Selection method a more reliable choice for residential calculations.
