RECORDED WEBINAR - UL Knowledge Services together with the National Electrical Manufacturers Association (NEMA) is pleased to offer a recorded webinar on Insulation Coordination for UL 60947-1 and UL 60947-4-1A.
This recorded webinar included discussion of principles and terms associated with insulation coordination, including creepage, clearance, material group categories, overvoltage categories and pollution degree. The course focused on in-depth explanations on how to measure creepage distances and clearances in accordance with UL 60947-1 from both an IEC and North American certification compliance perspective. Finally, we discussed clearances and creepage distance requirements as they relate to UL 60947-4-1A along with standard defined construction techniques for mitigating spacing construction concerns.
Topics covered in this workshop were:
- The UL and IEC approaches to insulation coordination
- Definition of terminology associated with insulation coordination
- UL 60947-1 and UL 60947-4-1A requirements for measuring creepage distance and clearances
- Annex G of UL 60947-1
- Annex C of UL 60947-4-1A
