Fuseholders - Part 19: Photovoltaic fuseholders
Scope:
Remarque : L'activité d'élaboration de normes de cet avis d'intention (initialement publié le 26 mars 2024) a été mise à jour par l'OEN responsable le 3 juillet 2024.
1.1
This Part is intended to be read together with the Standard for Fuseholders – Part 1: General Requirements, hereafter referred to as Part 1. The titles of the Clauses in this Part correspond to the similarly titled Clauses in Part 1. The requirements of Part 1 apply unless modified by this Part. For the Part 1 requirements, refer to the Standard for Fuseholders – Part 1: General Requirements, NMX-J-009-4248/1-ANCE / CSA C22.2 No. 4248.1 / UL 4248-1.
1.2
This Part applies to Fuseholders for Photovoltaic (PV) Systems rated to 2000 Vdc.
1.3
This Part applies to PV fuseholders that accommodate PV fuses as described in the Standard for Low-Voltage Fuses – Part 19: Photovoltaic Fuses, NMX-J-009/248/19-ANCE /CSA C22.2 No. 248.19 / UL 248-19 to be employed in Photovoltaic (PV) systems and that are intended to be used in accordance with the Canadian Electrical Code, Part I, CSA C22.1, the National Electrical Code, NFPA 70, and the Mexican Electrical Code, NOM-001.
1.4
Fuseholders that meet another Part also need to comply with those requirements of that Part.
Project need:
This proposal has been made to address the growth within the photovoltaic industry specific to the maximum voltage levels which are and will be made available. Increasing the voltage in the aforementioned standards will allow for manufactures to provide a certified and listed fuse to the market. Presently fuses with these ratings application are not covered under other standards. To revised existing requirement and align Canadian requirements with those of our harmonized partners from USA & Mexico in the subject area of Class CC fuseholders This proposed New Edition are being developed at the request of manufacturers, certification bodies, and the CANENA Technical Harmonization Committee 32B. It will provide the industry with latest requirement of Class CC fuseholders and improve the overall usability of the C22.2 No. 4248 series of Standards.
