Commercial Electric Cooking Appliances: Designing for Compliance to UL 197


This comprehensive one-day workshop will help engineers design commercial cooking appliances more rapidly by more thoroughly understanding the safety requirements needed to comply with UL 197. The course emphasizes the purpose of UL performance tests and construction, and their impact on appliance construction and functionality, rather than on a line-by-line review of the standard.  The connection between portions of the National Electrical Code and UL 197 is also covered, as engineers at times need to speak the language of the “code” with local AHJ’s. Descriptions of the types of markings used for installation and servicing are also provided during the course.

A copy of the UL 197 Standard is included with your workshop materials ($490 USD value).
