CSA C22.2 No. 214-17: Safety Standard for Communication Cables and Communication Equipment
An in-depth look at the scope, technical requirements, and compliance framework of the Canadian standard for communication cabling systems
Scope and General Overview
CSA C22.2 No. 214-17, Communication Cables and Communication Equipment, is a mandatory safety standard within the Canadian Electrical Code (CE Code) framework. It establishes the minimum safety requirements for communication cables and equipment intended for installation in ordinary locations and hazardous locations classified in accordance with the CE Code. The standard covers a wide range of products including coaxial cables, twisted‑pair cables, optical fiber cables, and associated equipment such as connectors, patch panels, and enclosures.
The 2017 edition supersedes the previous 2011 edition and introduces harmonized requirements with the latest US National Electrical Code (NEC) and UL standards, while maintaining distinctive Canadian safety criteria. It applies to products rated 50 V or less and intended for signaling, communication, or power‑limited circuits.
Technical Requirements
Fire Performance and Flammability
One of the central safety aspects of CSA C22.2 No. 214-17 is fire performance. Cables are classified according to their flame propagation and smoke generation characteristics. The standard references the same test methods used in the US (ANSI/UL 1685, ANSI/UL 2556) but with Canadian-specific smoke density criteria.
| Classification | Test Method | Flame Spread | Smoke Density |
|---|---|---|---|
| FT4 (Vertical Tray) | CSA C22.2 No. 0.3 (FT4) | ≤ 1.5 m from flame origin | Peak rate ≤ 0.25 m⁻¹ |
| FT6 (Riser) | CSA C22.2 No. 0.3 (FT6) | ≤ 1.5 m from flame origin | Peak rate ≤ 0.20 m⁻¹ |
| FT1 (General purpose) | CSA C22.2 No. 0.3 (FT1) | ≤ 0.5 m from flame origin | Not specified |
Tip: When selecting cables for high‑rise buildings, pay careful attention to the FT6 (Riser) classification. This is the most stringent Canadian fire rating and is comparable to the US NFPA 262 (Riser) test.
Electrical Safety Requirements
All equipment and cables must be designed to prevent electric shock, fire, and injury. Key electrical requirements include:
- Dielectric Withstand: Cables must withstand 1000 VAC for 1 minute between conductors and between conductors and shield (if any).
- Insulation Resistance: Minimum 100 MΩ·km at 500 VDC after water immersion.
- Clearance and Creepage: Equipment enclosures must provide at least 3.2 mm of creepage for basic insulation (working voltage up to 50 V).
- Bonding/Shielding: Shields must be bonded to the equipment grounding conductor in a manner that maintains integrity during normal operation and faults.
Warning: CSA C22.2 No. 214-17 does not permit the use of cables or equipment that rely solely on the communication cable shield for fault clearing. A separate bonding conductor is required unless the shield is specifically rated as a grounding conductor.
Mechanical and Environmental Requirements
Products must be robust enough to withstand installation and service environments. The standard includes tests for:
- Crush Resistance: Cables must survive a 445 N crushing force (applied for 5 minutes) without electrical breakdown.
- Temperature Rating: Cable jackets must be marked with the maximum operating temperature (e.g., 60 °C, 75 °C, 90 °C). All components must be thermally compatible.
- UV Resistance: If the cable is marked for outdoor use, it must pass a 720‑hour xenon‑arc exposure test (CSA C22.2 No. 0.3).
Implementation Highlights
Marking and Documentation
Every product that complies with CSA C22.2 No. 214-17 must carry the manufacturer’s identification, product designation, and the CSA mark (or an accredited certification mark). In addition, the following markings are required:
- Year of manufacture (or date code).
- Flame‑test classification (e.g., FT4, FT6).
- Voltage rating (or “CABLE − COMMUNICATION”).
- Maximum operating temperature.
Best Practice: Use the CSA Group’s online certification directory to verify that a specific product listing is current. Certified products are re‑audited annually to ensure continued compliance.
Testing and Certification Process
Manufacturers seeking CSA certification must submit representative samples to an accredited laboratory (CSA Group or a recognized third party). Testing includes:
- Full type‑testing per the applicable test methods listed in Annex A of the standard.
- Factory inspections (initial and periodic) to verify quality control and product consistency.
- Review of the product’s technical dossier including construction details, materials, and intended use categories.
Once certified, the manufacturer is authorized to apply the CSA mark and must maintain compliance through ongoing factory inspections and follow‑up testing.
Compliance Notes and Global Harmonization
CSA C22.2 No. 214-17 is largely harmonized with the US UL 444 (communication cables) and UL 1863 (communication circuit accessories) but contains notable differences:
| Area | CSA C22.2 No. 214-17 | UL 444 / UL 1863 |
|---|---|---|
| Riser flame test | CSA FT6 (modified Steiner tunnel) | UL 1666 (vertical shaft) |
| Plenum flame test | CSA FT6 (no plenum‑specific test) | NFPA 262 (Steiner tunnel) |
| Smoke measurement | Mandatory for FT4 & FT6 | Optional for most categories |
| Bonding wire requirement | Mandatory for shielded cables | Not required if shield is bonded via connector |
Caution: Products that are certified only to UL standards may not automatically comply with CSA C22.2 No. 214‑17. Even when tests are similar, the Canadian requirements for smoke density and bonding can lead to non‑compliance. Always verify the CSA mark or a recognized Canadian certification body (e.g., cUL, cETL) when selling into Canada.
Inspection and Enforcement
Enforcement of CSA C22.2 No. 214‑17 is carried out by provincial and territorial authorities having jurisdiction (AHJs) under the CE Code. Common compliance gaps found during field inspections include:
- Use of unmarked or improperly marked cables (e.g., lack of temperature rating).
- Installation of cables with an FT4 rating in vertical runs that require FT6.
- Failure to provide a separate bonding conductor for shielded communication cables.
To avoid project delays, specifiers should mandate CSA certified products and include the required classifications (including smoke density) in their purchasing documents.
Frequently Asked Questions
Q: Does CSA C22.2 No. 214‑17 cover the same products as UL 444 and UL 1863?
A: Yes, the scope is essentially the same: power‑limited communication cables and equipment rated ≤ 50 V. However, Canadian fire testing and bonding requirements differ, so a separate CSA certification is mandatory for the Canadian market.

Q: What is the difference between FT4 and FT6 flame test ratings?
A: Both are vertical tray tests, but FT6 is more stringent: it requires a lower peak smoke density (0.20 m⁻¹ vs. 0.25 m⁻¹) and a stricter flame propagation limit. FT6 is required for riser applications in buildings over 3 stories; FT4 can be used in general‐purpose and horizontal runs.

Q: Can I use a UL‑labeled cable in a Canadian installation?
A: Only if the UL label is accompanied by a “cUL” mark indicating certification to Canadian standards. Even then, verify that the cable’s flame classification (e.g., FT4, FT6) is included on the marking. Many cUL cables are dual‑listed, but some UL‑only cables lack the mandatory smoke density testing.

Q: Are there any significant changes in the 2017 edition compared to 2011?
A: Key changes include the adoption of a new smoke density measurement method (same as UL 2556), updated requirements for bonding conductors, and a revision of the marking requirements to include temperature ratings. The 2017 edition also clarifies the use of cables in hazardous locations.
