CEC conduit fill calculator
Size raceways with a Canadian conduit fill calculator that respects CE Code raceway fill practice. Ideal when you are bundling conductors in EMT, PVC, AC90, or TECK-style installations and need a clear fill percentage.

How this calculator works
Enter raceway type and each conductor or cable; the app totals cross-sectional area and compares it to allowable fill for the scenario you select.
CE Code alignment
Outputs follow the fill logic used for Canadian conduit and tubing work. Confirm specific rule selections and any local amendments on site.
Run in the app
Sign in to run the conduit fill calculator (pipe sizing workflow).
FAQ
- How do I calculate conduit fill in Canada?
- Use conductor and raceway dimensions with the fill rules applicable to your installation. Current Systems automates the geometry and fill percentage so you can size EMT, PVC, AC90, TECK-style runs, and mixed conductor bundles with less table lookup.
- Does the tool handle multiple conductors?
- Yes. You can combine multiple conductors and cables to see total fill and minimum trade size recommendations based on the inputs you provide.
- Is this a substitute for raceway tables in the code book?
- The calculator is a workflow aid. You remain responsible for verifying raceway type, derating context, and any project-specific constraints with the Canadian Electrical Code and AHJ.
