Low-voltage fuses - Part 19: Photovoltaic fuses
Scope:
Note: The standard development activity of this Notice of Intent (originally published on March 26, 2024) was updated by the responsible SDO on 3 July 2024.
1.1
This Part applies to fuses for photovoltaic (PV) systems rated up to 2000 Vdc.
1.2
Fuses for photovoltaic (PV) systems are intended to be used for the protection of photovoltaic strings or arrays and their associated wiring to provide protection against overloads or short circuits within the marked electrical ratings in accordance with the Canadian Electrical Code (CSA C22.1 Canadian Electrical Code Part I) in Canada, the Standard for Electrical Installations, NOM-001-SEDE, in Mexico and the National Electrical Code NEC), NFPA-70, in the United States of America.
1.3
These types of fuses are not intended to protect downstream inverter components, such as capacitors and against the discharge of such capacitors back into the arrays.
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
