3. I would like to mention one previous difference related to the smallest unit of indicated delivery that has been resolved. The CCR specification states that this value for, AC systems, shall not exceed 0.0001 kWh and for DC systems, shall not exceed 0.001 kWh. Editions of HB44 prior to the 2023 edition stated that this value shall be 0.001 kWh for both AC and DC systems. While never a real issue, The CCS wording was adopted into HB44 during the 2022 NCWM Annual Meeting and is first seen in the 2023 edition of HB44. The NTEP Certificate: An NTEP Certificate issued to an AC System will be what is referred to as a ‘full’ certificate meaning it is issued to a permanent code and without any limitations. However, a certificate issued for a DC System will have a Provisional status indicated by the CoC number having a “P” as the last character. The Provisional status is required as there is no certified testing equipment currently available for use during the eval - uation and there are no defined tolerances in HB44 for DC Systems. Both of these items are currently being worked on. Once the items are resolved, the system can be evaluated to the requirements and the Provisional Status can be removed. If you have any questions about the information in this article or need assistance with the application process, please contact the NTEP Administrator at darrell.flocken@ncwm.com or the NTEP Specialist at jeff.gibson@ncwm.com.
