Complete Technical Guide to Tri-Rated Cable — H05V2-K / H07V2-K / BS 6231 / UL1015 for Switchgear, Control Panels & Equipment Wiring
1. Introduction to CSA 22.2 No. 210-11 Cable
The Canadian Standards Association (CSA) sets out the requirements for the Canadian Electrical Code (Part 2) including flexible cords, elevator cables, and hoistway cables with a maximum voltage rating of 600V in the standard CSA 22.2. Standard CSA 22.2 Part 210-11 is designated for Appliance Wiring Material (AWM) Products such as heavy-duty cables with an increased voltage rating and a higher temperature rating than ordinary panel wires. The standard applies to both single conductor and multi-core cables, either round, flat, or coiled, which includes the range holding CSA, UL, and British Standard approvals.
Tri-rated cable is a high temperature, flame retardant electrical wire designed for use inside electrical equipment. Tri-rated cable meets the requirements of three different international standards: BS 6231, UL 758, and CSA 22.2. Combining three standards in one product makes tri-rated cable suitable for use in equipment that is required to meet both North American and British/European wiring regulations. This triple certification makes it highly sought-after around the world, particularly in the equipment export market, as it enables a leaner and more flexible equipment manufacturing process.

4. Voltage & Temperature Ratings by Standard
One of the key features of tri-rated cable is that it meets different voltage and temperature specifications depending on which standard is applied. UL and CSA give tri-rated cable a voltage rating of 600V, while it is rated at 1000V in the BS 6231 standard. Similarly, the maximum operating temperature varies between 90°C (BS 6231) and 105°C (UL/CSA).

7. Applications
Tri-rated cable is a fire retardant cable used in electrical cabinets, switch control, relay and instrumentation panels of power switchgear, and for internal connectors in rectifier equipment, motor starters and controllers. The cables are intended for use in the wiring of switch, control, metering, relay and instrument panels of power switchgear. They are intended for use at alternating voltages not exceeding 600V to earth and direct voltages not exceeding 1000V to earth.

8. European Harmonised (HAR) Designations
Under the European harmonisation system, tri-rated cables are also known as H05V2-K and H07V2-K cables. The designation depends on the conductor cross-sectional area and corresponding voltage rating. BS EN 50525-2-31 covers harmonised conductor sizes up to 35mm², with cables above this size generally manufactured to the same specification.
| Code Element | Meaning |
|---|---|
| H | Harmonised (HAR) cable |
| 05 / 07 | Voltage rating: 05 = 300/500V, 07 = 450/750V |
| V2 | PVC insulation, heat resistant (T13 compound) |
| -K | Flexible conductor (Class 5) |
HAR Designation by Conductor Size
| Conductor Size | HAR Designation | Voltage Rating | Standard |
|---|---|---|---|
| 0.5mm² – 1mm² | H05V2-K | 300/500V | EN 50525-2-31 |
| 1.5mm² and above | H07V2-K | 450/750V | EN 50525-2-31 |
