Demand load calculation from your actual design
NEC 220 demand factors applied to the real loads in your model. Connected load, demand load, and service requirements — all calculated from the one-line diagram, not a separate spreadsheet.
What you get
Standard demand factors applied per NEC Article 220 based on load type and quantity.
Total connected load calculated from all devices in your model.
Demand load derived from connected load using applicable demand factors.
Calculated demand drives service entrance sizing — main breaker, conductors, and grounding.
Loads classified by type (lighting, receptacle, motor, HVAC) for proper demand factor application.
Add or change any load and demand calculations update throughout the system.
Demand calculation connected to your design
Spreadsheet demand calculations drift out of sync with the design. In ekx, demand load is calculated directly from the loads in your model — always accurate, always current.
- Connected loads feed directly into demand calculation
- Demand factors apply based on load type and NEC requirements
- Service entrance sizes from calculated demand automatically
- Add a load and demand recalculates throughout the system

NEC Article 220 for demand factor calculations, including standard and optional calculation methods.
Yes. Loads are classified by type — general lighting, receptacles, motors, HVAC, cooking equipment, etc. — and the appropriate NEC demand factors apply.
No. Demand load is calculated from the actual loads in your one-line diagram model. It's not a separate data entry exercise.
Yes. The calculated demand load drives service entrance sizing — main breaker rating, service conductor size, and grounding electrode conductor size.
