CEC Compliance Report (Simplified)

  • Load a preset or configure parameters to begin analysis.
Disclaimer: This tool is for educational purposes only. It performs simplified checks based on CEC (Canadian Electrical Code) concepts like Rule 8-102 (Voltage Drop), 8-104 (Continuous Load), and 14-104 (Small Conductors). It ignores factors like temperature derating, conduit fill, specific equipment ratings, and fault current. Always consult a qualified electrician or engineer.

SimpeElecCECCheck

Explore a transformer and feeder configuration through a single-line diagram with simplified Canadian Electrical Code checks.

What this tool does

SimpeElecCECCheck visualizes a utility source, primary protection, transformer, panel, secondary protection, and load. It calculates estimated full-load current, voltage drop, conductor ampacity, and load voltage, then presents a simplified compliance report.

Who this is for

How to use this tool

  1. Choose a preset configuration or select Configure Parameters
  2. Enter primary supply, protection, conductor, material, and circuit-length values
  3. Enter transformer capacity and secondary voltage, then configure the secondary circuit and load
  4. Review the single-line diagram, calculated values, and simplified CEC Compliance Report

Inputs

Inputs include preset selection, primary supply voltage, primary OCPD rating, conductor AWG and material, primary circuit length, transformer kVA and secondary voltage, secondary protection and conductor settings, and load values.

Outputs

The diagram shows source, protection, transformer, panel, and load values. Calculated results include primary and secondary FLA, secondary voltage drop, voltage at load, and primary and secondary wire ampacity, followed by status items in the compliance report.

Example use cases

Limitations and safety

This tool performs simplified educational checks based on selected Canadian Electrical Code concepts, including voltage drop, continuous load, and small-conductor rules. It does not account for every code requirement, temperature derating, conduit fill, equipment rating, fault current, site condition, or authority having jurisdiction. Do not use it as a permit, installation, or safety decision; always consult a qualified electrician or engineer.

Frequently asked questions

What code checks are included?

The simplified report considers selected voltage-drop, continuous-load, and small-conductor concepts. It shows calculated values and warning or failure states for the configured scenario.

Can I start from a preset?

Yes. Choose a preset from the toolbar, or open Configure Parameters to enter a custom primary, transformer, secondary, and load setup.

Is this a substitute for a code review?

No. It is a simplified educational visualizer. A qualified electrician or engineer must verify any real installation against the current code, equipment documentation, and site conditions.
