Impact Statement: A review of all Listing Reports is necessary to determine which products comply with new/revised requirements and which products will require re-evaluation. NOTE: Effective immediately, this revised standard will be exclusively used for evaluation of new products unless the Applicant requests in writing that current requirements be used along with their understanding that their listings will be withdrawn on Effective Date noted above, unless the product is found to comply with new/revised requirements.
Overview of Changes(Specific details of new/revised requirements are found in table below): Deviation added to clause 10.2 – limitation on rated power input. Specific details of new/revised requirements are found in table below.
- Addition of marking of allowable amperage of field installed conductors
- Addition of marking where a transfer switch is included.
- Addition of finger probe requirements
Schedule: So that shipping of products with Listing Marks will not be interrupted, an approximate schedule has been established to ensure Listing Reports are found compliant by Effective Date:
- December 28, 2015 = 8 Month Report Review – Intertek will review all Reports. Update if compliance is verified or issue Findings Letter/Quote for any re-evaluations needed
