Q: Will Grace products affect the NRTL (Nationally Recognized Testing Laboratories) rating of a application they are installed on?

A: As long as Grace Technologies products are installed in enclosure with other equipment meant for the certified safety rating intended for the environment they are in, Grace products will not affect the NTRL rating of the application. NTRL is not affected as long as instructions for installation are followed as well the NEC(National Electric Code) or the CEC (Canadian Electrical Code). Follow all Local, State, and National Electrical Codes when
installing our equipment.
