What does the term "connected load" refer to?

The term "connected load" refers to the total wattage of all devices that can potentially draw power from the system. This measurement includes the sum of the rated load of all the electrical devices and loads connected to a power source, regardless of whether they are currently in operation. It represents the maximum possible demand on the electrical system if all connected devices were to draw power simultaneously.

Understanding connected load is critical for designing electrical systems and ensuring that feeders and services are adequately sized to handle the load under peak conditions. While actual power consumption during operation reflects the real-time usage of electricity and idle power measures passive energy use, connected load provides a broader overview of capacity planning. Power loss in the distribution system pertains to inefficiencies in energy transmission rather than the total load that could be drawn.
