Load and demand
Compare connected and design load, apply circuit diversity and include power factor when calculating current and apparent power.

Temporary Power Calculations Software
LVA Power Planner connects temporary-power calculations to the sources, distribution equipment and circuits they describe. Designers can move from connected load to planned demand without rebuilding the same system across separate spreadsheets.
Cable design
Review cable capacity, parallel runs, derating, section voltage drop, cumulative voltage drop and estimated end voltage.
Connected system
Propagate downstream distro demand through upstream circuits so calculations remain tied to the planned distribution hierarchy.
