CEC Compliance Status (Simplified)

  • ℹ️ Configure parameters to see compliance checks.
Disclaimer: This tool performs *highly simplified* checks based on common interpretations of the Canadian Electrical Code (CEC), assuming standard conditions. Key rules considered include 8-102 (Voltage Drop Recommendation - Secondary), 8-104 (Continuous Load - Secondary), 14-104 (Secondary OCPD/Wire), and basic transformer protection concepts (Ref Rule 46-204, simplified). Primary side checks (wire ampacity, protection) are basic estimates. This is NOT a substitute for professional engineering/electrical design or full CEC analysis. Many factors (transformer impedance, inrush current, specific equipment, temperature/conduit derating, local amendments, grounding/bonding, 3-phase systems) are NOT fully accounted for. Always consult the complete, current CEC and/or a qualified person.
