NEC compliance, built in
Cable sizing, overcurrent protection, derating factors, and voltage drop — all checked against NEC 2023 automatically as you design. No separate compliance step.
What you get
Sizing and compliance checks reference the current National Electrical Code.
Conductor sizing based on NEC ampacity tables with proper temperature ratings.
Overcurrent protection sizing following NEC 240 requirements and standard sizes from 240.6.
Automatic application of conduit fill, ambient temperature, and bundling derating per NEC.
125% continuous load factor applied automatically per NEC requirements.
Non-compliant selections are flagged automatically. No manual cross-checking needed.
NEC compliance as part of the design process
Instead of checking NEC compliance as a separate step after design, ekx checks it continuously as you build. Every cable, every breaker, every circuit — always compliant.
- Equipment sizes follow NEC requirements from the start
- Derating factors apply automatically based on installation conditions
- Non-compliant configurations are flagged in real time
- Manual overrides are checked against NEC minimums

NEC 2023. Ampacity tables, derating factors, and overcurrent protection requirements all reference the current edition.
For cable sizing, OCPD sizing, and derating factors — yes. ekx automates the table lookups and calculations. You should still apply engineering judgment and verify results.
ekx follows the national code. Local amendments or AHJ-specific requirements should be verified separately by the engineer of record.
Derating for conduit fill, ambient temperature, and bundled conductors is handled automatically. You configure the installation conditions, and ekx applies the correct factors.
NEC compliance built into every design decision.
Stop flipping through code books. Let ekx check compliance automatically.
