Electrical System Designer

Size panels, branch circuits, conductor runs and short-circuit interrupting capacity for your facility. Includes IEC 60909 short-circuit calculations, motor-starting analysis (DOL / wye-delta / soft-start / VFD), and per-run voltage-drop check against NEC recommendations.

Facility footprint: 40 × 20 × 12 ft (default; open the designer to use your real footprint)

Lighting Electrical

Place fixtures in the designer and they'll be sized into circuits here — connected load, service size, and a panel schedule.

Facility workspace below is demo data — the 1,525A service, panels, and equipment in the visualization that follows are illustrative. The lighting circuits and load above ARE computed from your design; full multi-system panels come from per-circuit measurements once configured.

Planning estimate only — not a stamped design. These calculations reference the National Electrical Code (NEC / NFPA 70); the adopted code edition and local amendments vary by jurisdiction. Confirm the applicable edition and all requirements with your local Authority Having Jurisdiction (AHJ), and have a licensed electrical engineer (PE) review and approve the final design before installation.
