UL 1310 (Class 2) — Power Unit Safety
UL 1310 is the U.S. safety standard for Class 2 power units — low-voltage, limited-power supplies that simplify installation wiring. YHYadapter provides UL 1310 Class 2 certification availability on select power adapter models for North American market requirements.
What is UL 1310?
UL 1310 covers Class 2 power units with limited output power and voltage characteristics. Class 2 circuits have fewer conduit and installation restrictions than Class 1 circuits, simplifying luminaire and low-voltage product wiring in the United States.
UL 1310 and UL 1012 are separate U.S. safety routes and must not be merged or cross-labeled. UL 1310 Class 2 is not automatically applicable to all low-power adapters — applicability depends on model-level certification evidence.
Confirmed Model Evidence
Available by model — 8 models confirmed (EVID-006/007): UL certificate UL-US-2018654-0 (UL LLC) and ETL certificate 22100852HKG-001 (Intertek) support Class 2 certification on select YHYadapter models. Certification availability varies by model and configuration.
Why UL 1310 Matters
Simplified Wiring
Class 2 circuits require fewer conduit and distance restrictions than Class 1 circuits in US installations.
North American Access
Supports compliance requirements for products entering US and Canadian markets.
Evidence-Driven
YHYadapter applies the Class 2 claim only where model-level evidence supports it.

UL 1310 Frequently Asked Questions
Is the YHYadapter adapter certified to UL 1310 Class 2?
Certification availability is model-dependent. Eight YHYadapter models are confirmed with Class 2 evidence (EVID-006/007). Verify your specific model with our engineering team.
What is the difference between Class 2 and non-Class 2 power units?
Class 2 power units (UL 1310) have limited output power and voltage, allowing simpler wiring methods. Non-Class 2 units require Class 1 wiring (conduit) in most US installations.
Is UL 1310 the same as UL 1012?
No. They are separate U.S. safety routes and must not be merged or cross-labeled.
How can I verify a specific model?
