Getting Tied to the Right Standard
UL 62275 establishes the performance and safety requirements for cable ties used in electrical installations, defining how they are tested, classified, and marked for compliant field use. The standard aligns U.S. and Canadian expectations through its harmonization with CSA C22.2 No. 62275 and provides the framework inspectors rely on when evaluating whether a tie is suitable for securing or supporting conductors in different environments.
The following questions outline the key requirements installers should understand when selecting cable ties that meet UL 62275.
UL 62275 Cable Tie Requirements
1. What does UL 62275 cover?
UL 62275 defines the performance, construction, and testing requirements for cable ties and associated fixing devices used in electrical installations. It applies to nonmetallic, metallic, and composite ties and establishes minimum mechanical, thermal, and environmental performance. The standard is harmonized with CSA C22.2 No. 62275, aligning U.S. and Canadian requirements.
2. How does UL 62275 classify cable ties?
UL 62275 uses “Type” designations to indicate performance and material qualification:
- Type 1 — Nonmetallic/composite ties meeting baseline requirements
- Type 11 — Type 1 with enhanced long‑term material performance
- Type 2 — Metallic or nonmetallic ties retaining full strength after conditioning
- Type 21 — Type 2 with enhanced long‑term material performance
- Type 2S / 21S — Ties additionally qualified to support conduit or cable during construction
3. What does “Type 21S” mean?
Type 21S ties meet all Type 21 requirements and are additionally tested to support conduit or cable during building construction, making them suitable when ties serve as primary support rather than bundling.
4. Are UL 62275 cable ties Listed or Recognized?
Cable ties may be UL Listed for field installation or UL Recognized as components for equipment. Listed ties fall under UL Category ZODZ; Recognized components fall under ZODZ2.
5. Does UL 62275 replace UL 1565?
Yes. UL 62275 supersedes UL 1565 and is the harmonized standard for cable ties used in electrical installations across the U.S. and Canada.
6. Can any UL‑marked cable tie be used in electrical installations?
No. Only cable ties evaluated to UL 62275 are acceptable for electrical installations. Cable ties marked only as UL Recognized under unrelated categories, or ties evaluated for packaging or general‑purpose use, are not approved for securing or supporting conductors. Installers must verify the tie is specifically evaluated to UL 62275 and marked with the correct Type classification.
7. Can UL 62275 cable ties be used in plenum spaces?
Only cable ties that are additionally evaluated to UL 2043 are acceptable for use in environmental air (plenum) spaces. UL 62275 alone does not qualify a tie for plenum use. The product must be marked or documented as UL 2043‑rated to meet flame‑spread and smoke‑generation requirements.
8. Do all UL 62275 cable ties have the same temperature rating?
No. UL 62275 cable ties are tested and marked for specific temperature ratings, and installers must select ties appropriate for the environment. Common ratings include 85°C and 105°C, but higher‑temperature metallic ties may be rated above this range. Using a tie outside its marked temperature rating can lead to premature failure and inspection issues.
9. Are all UL 62275 cable ties suitable for outdoor or UV‑exposed environments?
No. UL 62275 includes UV exposure testing, but only ties specifically marked or documented as UV‑rated are suitable for outdoor use. Installers must verify UV suitability when ties are used on rooftops, exterior conduit, solar arrays, or other sun‑exposed locations.
With these criteria understood, installers can confidently select cable ties that meet UL 62275 expectations.
