Cable lengths (to determine voltage drop).Conductor types (i.e., cable or busway) and sizes.Overcurrent / short-circuit protection.Electrical distribution equipment ampacity and short-circuit ratings.
Incoming service voltage and utilization voltages required.Initially, the Single Line Diagram (SLD) provides a framework for the incorporation of different types of required information such as: It then follows the power flow down through the various conductors as well as any voltage transformations to feed distribution equipment buses for the key loads served. Single line drawing starts with the incoming power source from the utility service and/or on-site generation and their associated distribution equipment.
