Under normal conditions, a PV module may produce more current and/or voltage than reported at Standard Test Conditions. Accordingly, the values
of Isc and Voc marked on UL 1703 listed modules should be multiplied by a factor of 1.25 when determining component voltage ratings, conductor
ampacities, fuse sizes and size of controls connected to the module output. Refer to Sec. 690-8 of the National Electric Code for an additional
multiplying factor of 125 percent (80 percent de-rating) which may be applicable. Where Canadian UL listing applies, installation shall be in
accordance with CSA C22.1, Safety Standard for Electrical Installations, Canadian Electrical Code, Part 1.
