🇨🇦 Canadian Electrical Guides

Written to the Canadian Electrical Code — where the voltage-drop limit is mandatory, the cable is NMD90, and the code speaks metric. 🇺🇸 US guides

How these guides are made

Every number comes from our verified data tables — Canadian ampacity values confirmed harmonized with the tables we verified against published code reproductions — and the Canadian rules cited here (Rule 8-102, 4-006, 14-104, Table 68) were researched against Canadian sources including ESA bulletins. The calculators these guides link to work for Canadian circuits directly: same wire sizes (Canada uses AWG), same physics, with the Canada edition selected. Planning reference, not a substitute for a licensed electrician or your provincial inspection authority.
