Understanding CSA C22.2 No. 198.1-06 (R2015): Canadian Standard for Plugs, Receptacles, and Similar Wiring Devices
Scope, Technical Requirements, and Compliance for Electrical Wiring Devices in Canada
Scope and Application
CSA C22.2 No. 198.1-06 (R2015) – hereafter referred to as CSA 198.1 – is the primary Canadian standard for plugs, receptacles, and similar wiring devices intended for connection to branch circuits. Developed under the Canadian Electrical Code (CE Code) framework, this standard covers devices rated up to 600 V and up to 200 A, including attachment plugs, cord connectors, receptacles, current taps, and other interconnecting wiring devices used in ordinary (non-hazardous) locations.
The standard harmonizes closely with UL 498 (Standard for Attachment Plugs and Receptacles) and is part of the bi-national effort to align electrical safety requirements across North America. CSA 198.1 applies to devices installed in accordance with the CE Code, Part I, and is referenced by provincial and territorial authorities having jurisdiction.
Tip: CSA C22.2 No. 198.1-06 (R2015) was reaffirmed in 2015 without significant technical changes. Always verify the latest amendment status when designing for the Canadian market.
Technical Requirements
Construction and Materials
Devices covered by CSA 198.1 must be constructed of materials resistant to impact, heat, and moisture. Current-carrying parts are required to be of copper or copper alloy, and live parts must be protected against accidental contact. Receptacles must incorporate shutters (for tamper-resistant constructions when mandated) or alternative designs that prevent insertion of a single blade. Specific requirements include:
- Minimum pull-out force of 15 N (3.4 lbf) for attachment plugs.
- Dielectric voltage withstand of 1500 V between live parts and accessible metal.
- Secure terminal connections capable of accepting copper or aluminum conductors as per CE Code.
- Marking of current rating, voltage rating, and manufacturer identification.
Performance and Testing
Manufacturers must subject devices to a series of type tests. The table below summarizes key test parameters:
| Test | Condition | Requirement |
|---|---|---|
| Temperature rise | At rated current | ≤ 30 °C rise above ambient |
| Dielectric voltage | 60 Hz, 1 min | No breakdown at 1500 V |
| Overload | 1.25 × rated current, 50 cycles | No damage or interruption |
| Mechanical endurance | 6000 cycles (plug/receptacle) | No loosening of parts |
| Strain relief (cord connectors) | 80 N pull for 1 s | Cord must not displace |
Grounding and Polarization
The standard mandates grounding for all receptacle configurations rated 125 V and above, with grounding blades configured to ensure first-make, last-break continuity. Polarization is required for 125 V, 15 A and 20 A configurations, aligning with NEMA configurations. Devices for use with aluminum conductors must have terminals marked “AL” and be evaluated for compatibility.
Warning: Devices that do not comply with the grounding polarity requirements of CSA 198.1 may not be acceptable for installation under the CE Code. Always confirm grounding continuity and blade orientation during design verification.
Implementation Highlights
For manufacturers and specifiers, implementing CSA 198.1 involves several critical steps:
- Certification: All devices must be certified by an accredited organization (e.g., CSA Group, UL, Intertek) to ensure compliance. Certification typically covers construction review, testing, and ongoing factory inspections.
- Marking: Devices must bear the certification mark (e.g., CSA Mark) and the rating information. For receptacles with integral shutters, the words “Tamper Resistant” or “TR” must appear.
- Wiring configurations: The standard references NEMA configuration designations for non-locking and locking types. Receptacles must be marked with the appropriate configuration designation (e.g., NEMA 5-15R).
- Field installation: Installers must follow the CE Code requirements for box size, conductor size, and torque values. Receptacles installed outdoors require weather-resistant covers and must comply with additional provisions in CSA 198.1.
Best practice: Early engagement with a certification body can streamline the compliance process. Submitting design documentation and sample devices for preliminary review reduces the risk of costly redesigns.
Compliance Notes
Compliance with CSA 198.1 is mandatory in all Canadian jurisdictions under the CE Code. Key compliance points include:
- Harmonization with UL 498: While the standards are closely aligned, differences exist (e.g., Canadian ambient temperature rating of 30 °C vs. US 25 °C). Devices certified to both standards typically carry a bi-national mark.
- Aluminum conductor compatibility: Receptacles listed for aluminum wiring must meet additional heat cycle tests (500 cycles at 100 % rated current). Marking requirements for “AL” and “CO/ALR” are specified.
- Tamper-resistant (TR) receptacles: Since 2015, the CE Code requires TR receptacles in all dwelling units. CSA 198.1 includes construction and test requirements for the shutters.
- Renewal and amendments: The standard is periodically updated. At the time of writing, the 2015 reaffirmation is current; users should monitor CSA Group announcements for new editions.
Critical: Non-compliant devices can lead to installation rejections, product recalls, and liability issues. Always source devices bearing a recognized certification mark and maintain traceability records.
Frequently Asked Questions
Q: Does CSA C22.2 No. 198.1-06 (R2015) cover GFCI or AFCI receptacles?
A: No. This standard deals only with basic wiring devices. Ground-fault circuit-interrupters (GFCIs) and arc-fault circuit-interrupters (AFCIs) are covered under separate standards (e.g., CSA C22.2 No. 144.1). However, the physical plug and receptacle portions of those devices must still comply with the dimensional and strength requirements of CSA 198.1.

Q: What is the relationship between CSA 198.1 and the Canadian Electrical Code?
A: CSA 198.1 is one of many standards referenced by the CE Code (CSA C22.1). Section 26 of the CE Code mandates that plugs, receptacles, and similar devices conform to CSA 198.1. Therefore, it is a normative part of the regulatory framework.

Q: Can a product certified to UL 498 alone be sold in Canada?
A: Not without additional evaluation. While the standards are harmonized, UL 498 certification does not automatically satisfy all Canadian requirements. Manufacturers must obtain a separate CSA certification or a bi-national listing that confirms compliance with CSA 198.1.

Q: Are there any unique marking requirements for Canada?
A: Yes. In addition to the CSA mark, devices must be marked with the electrical ratings, configuration identifier (e.g., NEMA 5-15R), and, if applicable, “Tamper Resistant” or “TR”. Devices rated for aluminum conductors must show “AL” or “CO/ALR”. All marking must be durable and legible after installation.
