CEC tap conductor calculator

Check tap conductor sizing against CE Code tap practices, including common 3 m and 7.5 m scenarios. Built for Canadian electricians who need defensible documentation on taps fed from larger feeders.

How this calculator works

Enter upstream feeder ampacity, tap length, load, and protection details. The app evaluates the tap against the rule set implemented for Canadian installations.

CE Code alignment

The checks follow Canadian Electrical Code tap conventions. Confirm rule selection with the code edition adopted in your jurisdiction.

FAQ

What are tap conductor rules in Canadian work?
Tap rules allow smaller conductors than the upstream feeder when specific length, protection, and ampacity conditions are met. A calculator helps you verify those relationships for common 3 m and 7.5 m tap scenarios.
Does the tool cover both short tap lengths?
Yes. You can work through the tap scenarios supported in the app, including the commonly referenced short tap lengths used in Canadian designs.
Should I still coordinate with overcurrent protection?
Absolutely. Tap conductors must be compatible with upstream and downstream overcurrent devices. The tool helps document sizing relationships; field devices must match the approved design.
