⚡ Reactive Project Workflow

One state. Edit any section. Everything updates.

Service, panels, loads, feeders, voltage drop, single-line diagram — they all bind to the same project state. Edit any field anywhere and the entire derived project recomputes against the active rule pack (NEC 2023 or CEC 2024). Override a feeder OCP and the conductor resizes; push it past the upstream OCP and a coordination violation surfaces.

Sandbox — project not yet saved to DB. Local edits only.

5 Feeder overrides — engineer-set OCP / conductor

Override a feeder's OCP or conductor to override the engine. Conductor auto-resizes for OCP overrides; if the override violates upstream coordination (downstream OCP > service OCP) a violation is flagged below in real time.
