CSA C22.2 No. 81-14 (2019): Safety Standard for Household and Similar Electrical Appliances
Comprehensive Guide to Canada’s 14th Edition National Safety Standard for Cord-and-Plug-Connected Appliances
Scope and Application
CSA C22.2 No. 81-14 (2019) is the 14th edition of the Canadian national safety standard for household and similar electrical appliances. It applies to appliances for household and similar purposes, with a rated voltage not exceeding 250 V for single-phase appliances and 480 V for other appliances. The standard covers both cord-and-plug-connected appliances and those intended for permanent connection to the electrical supply.
This standard is the Canadian adoption of IEC 60335-1 Ed. 5.2 (Safety of household and similar electrical appliances – Part 1: General requirements), incorporating national differences that reflect Canadian electrical codes, environmental conditions, and language requirements. It serves as the basic safety standard for a wide range of household appliances, including kitchen appliances, cleaning equipment, heating devices, and personal care products.
The scope explicitly excludes:
- Appliances intended exclusively for industrial or commercial use
- Appliances for hazardous locations (unless specifically referenced)
- Appliances that are part of building installation (e.g., wiring systems)
- Appliances with heating elements immersed in liquids where special requirements apply
Technical Requirements
Construction and Marking
The standard establishes rigorous construction requirements to ensure safety under normal and abnormal use. These include:
- Protection against electric shock (clearances, creepage distances, insulation coordination)
- Heating and temperature rise limits for materials and accessible surfaces
- Mechanical strength and stability
- Protection against moving parts and other mechanical hazards
- Resistance to fire and heat (glow-wire tests, ball pressure tests)
National Differences from IEC 60335-1
CSA C22.2 No. 81-14 includes specific deviations for Canada. Key differences are summarised in the table below.
| Requirement Area | IEC 60335-1 Ed. 5.2 | CSA C22.2 No. 81-14 Deviation |
|---|---|---|
| Rated voltage | Up to 250 V single-phase | Up to 250 V single-phase supported for Canada (120/240 V 60 Hz system) |
| Supply cord & plug | Min. cord length, no polarisation requirement | Polarised plugs (NEMA 1-15P or 5-15P) required for certain classes; specific cord types (e.g., NMD-90 for built-in appliances) |
| Marking language | English or French optional | Mandatory bilingual marking (English and French) on appliance and packaging |
| GFCI / Leakage protection | Leakage current limits only | Additional GFCI requirements for appliances in damp locations (e.g., portable heaters, pumps) |
| Installation reference | IEC 60364 | Must comply with Canadian Electrical Code (CEC) Part I (CSA C22.1) |
| Temperature class | According to IEC 60335-1 | Same, but with additional derating for ambient conditions typical of Canadian climates (summer/winter extremes) |
Tip: Manufacturers seeking CSA certification should carefully review the national differences document (C22.2 No. 81-14) before testing, as even small deviations from the IEC base can affect product design and certification cost.
Testing and Verification
All appliances must undergo type-testing for compliance. Critical tests include:
- Dielectric voltage-withstand test (hi-pot)
- Leakage current measurement at operating temperature
- Abnormal operation tests (locked rotor, blocked air intake, etc.)
- Rain test (for outdoor or laundry appliances)
- Drop and impact tests for portable appliances
Implementation Highlights for Manufacturers
To bring a compliant product to the Canadian market, manufacturers should follow these steps:
- Identify applicable part‑2 standards: Most household appliances require a particular part (e.g., C22.2 No. 81‑2 for vacuum cleaners, 81‑3 for dishwashers, 81‑4 for washing machines, etc.). The general part and the particular part must be used together.
- Design to Canadian voltage and frequency: 120 V / 60 Hz (single-phase) or 208 V–240 V / 60 Hz (three-phase). Supply cords must be rated for the Canadian system and terminated with the appropriate NEMA plug types.
- Prepare bilingual documentation: Instruction manuals, labels, and warnings must be in English and French as required by Canadian consumer protection laws.
- Select an accredited certification body: CSA Group itself, UL (as SCC‑accredited), Intertek, or other Organizations accredited by the Standards Council of Canada (SCC) for product safety certification.
- Plant inspection and factory follow-up: Certification includes initial factory inspection and periodic unannounced audits to ensure ongoing compliance.
Best Practice: Engage a local certification engineer early in the design phase to review the standard’s national differences. This can reduce redesign costs and shorten time-to-market.
Compliance Notes
Transition from Previous Editions
CSA C22.2 No. 81‑14 (2019) replaced the earlier Edition 13 (C22.2 No. 81‑10, published 2010). The transition period allowed products certified to 81‑10 to be sold for a limited time, after which all new certifications had to meet 81‑14. Key changes include alignment with IEC 60335‑1 Ed. 5.2 (which introduced new requirements for electronic circuits, motor overtemperature protection, and enhanced fire test criteria) and updated national differences for Canadian plug-polarity and GFCI requirements.
Common Pitfall: Overlooking the requirement for polarised plugs on certain Class I appliances. Even if the IEC base does not mandate polarisation, the Canadian deviation does. Failure to address this can lead to certification delays.
Certification Marks
Products certified to CSA C22.2 No. 81‑14 typically bear one of the following marks:
- CSA Mark (Canadian Standards Association)
- cUL or cULus Mark (Underwriters Laboratories, indicating compliance with both Canadian and US standards)
- ETL cETLus Mark (Intertek)
The mark confirms that the product has been tested and meets the requirements of the standard and applicable provincial regulations.
Critical Non-Compliance Risk: Selling an appliance in Canada without the appropriate certification mark is illegal under provincial electrical safety acts. Non‑compliant products can be subject to seizure, fines, and liability for damages.
Maintaining Compliance
After certification, manufacturers must:
- Notify the certification body of any product changes that could affect safety.
- Maintain traceability of materials and components.
- Participate in follow-up inspections (typically quarterly).
- Respond promptly to any corrective action requests from the certification body or market surveillance.
Frequently Asked Questions
Q: What is the relationship between CSA C22.2 No. 81‑14 and IEC 60335‑1?
A: CSA C22.2 No. 81‑14 is the Canadian adoption of IEC 60335‑1 Ed. 5.2 with national differences. It includes all the IEC requirements plus deviations specific to Canadian electrical practice, language, and safety regulations. Manufacturers can use a single test report for both IEC and CSA compliance if the testing covers the Canadian deviations.

Q: Does the standard apply to commercial or industrial appliances?
A: The standard covers household and similar appliances. Appliances intended for commercial or industrial use are generally covered by other standards in the C22.2 series (e.g., No. 0, No. 169, No. 250). However, some appliances used in light commercial environments (e.g., hotel kitchen equipment) may still fall under No. 81‑14 if they are of a type typically used in households.
