Quebec electricians work under the CEC 2021 with provincial amendments. Whether you are sizing a service entrance, calculating voltage drop on a long feeder run, or verifying conduit fill for a commercial panel installation, SparkShift's 40+ CEC calculators run in any browser and require no sign-up.
Province note: Quebec uses Chapter V of the Quebec Construction Code (Code de construction du Québec), which is based on CSA C22.10 (the Québec-specific CEC adaptation) with additional Quebec amendments. The code is enforced by the Régie du bâtiment du Québec (RBQ). Quebec's electrical code has historically followed the CEC with significant provincial modifications, including language-specific terminology and some differing requirements for residential and commercial installations. Always verify the current edition of Chapter V and any amendments with the RBQ.
Electrical safety in Quebec is regulated by the Régie du bâtiment du Québec (RBQ). All SparkShift calculations can be toggled between CEC and NEC editions using the standard picker on each calculator.

Yes — the Canadian Electrical Code (CEC, CSA C22.1) and the US National Electrical Code (NEC, NFPA 70) are separate standards developed by different organizations. While they share many concepts, specific values differ: the CEC uses metric units in many tables, has different demand factors, different conduit fill rules, and different allowable ampacity tables (CEC Table 2 vs. NEC Table 310.16). SparkShift supports both CEC and NEC standards — use the code standard picker in each calculator to select the appropriate edition.
Yes — virtually all Quebec jurisdictions require an electrical permit and inspection for service upgrades, panel replacements, new branch circuits, and other significant electrical work. The permit is obtained through your local AHJ, which may be the Régie du bâtiment du Québec (RBQ) directly, or a municipality or utility with delegated authority. Contact the Régie du bâtiment du Québec (RBQ) for specific permit requirements in your area.
