Which component is NOT typically included in a load calculation?

When conducting a load calculation for electrical systems, the primary goal is to determine the power requirements and size of the electrical components necessary to ensure safe and efficient operation.

In the context of load calculations, the type of conductors, voltage levels, and power requirements of connected devices are all essential factors that directly impact the design and functionality of the electrical system. These elements help in selecting the appropriate conductors and protective devices and determining the overall system capacity.

On the other hand, the physical size of wiring conduit is not a factor in the load calculation itself. While conduit size is important for protecting wires and ensuring compliance with installation standards, it does not influence the electrical load or safety calculations. Load calculations focus on power demand and circuit design rather than the conduit sizes required for installation. This distinction clarifies why the physical size of wiring conduit is not typically included in load calculations.
