CEC Compliance Status (Simplified)
ℹ️Select an installation type or enter custom values to see compliance checks.
Disclaimer: This tool performs *simplified* checks based on common interpretations of the Canadian Electrical Code (CEC), assuming standard conditions (e.g., Table 2/4, 75°C termination, ≤3 conductors in raceway/cable, 30°C ambient).
Key rules considered include 8-102 (Voltage Drop Recommendation), 8-104 (Continuous Load - 80% Rule), and 14-104 (Overcurrent Protection Rating vs. Conductor Ampacity).
This is NOT a substitute for a full CEC analysis or professional consultation. Factors like ambient temperature derating, conduit fill derating, specific equipment requirements, local amendments, and voltage system details (e.g., 120/240 vs 120/208) are NOT fully accounted for. Always verify calculations and consult the complete, current CEC and/or a qualified person for any real-world installation.
