Equipment to meet the requirements of the Ontario Electrical Safety Code must be approved to Canadian standards.
Electrical component parts in primary circuits of equipment shall be of types specifically approved for the use intended or shall be investigated with, and as an integral part of, the equipment.
This is signified by the "C" outside the Entela, ETL, MET, OMNI, QAI, TUV Rheinland and UL marks.
The “NRTL/C” shown with one Canadian Standards Association mark, and the “cULus” shown with one Underwriters
Laboratories mark, indicate the equipment with those marks is also compliant with United States standards.
A Canadian Standards Association mark with "NRTL" only, and Underwriters Laboratories mark without the “c” at
the eight o’clock position, indicates the equipment is compliant with United States standards.
