Interesting question concerning XLPE cover on PV cabling to interior raceway installations. As one might know that cross-linked polyethelyne is a sunlight-flame resistant cover (over the primary XHHW conductor insulator) used on USE (Direct Burial) and triplex (Drop cabling) that are not dwelling indoor permitted according to the NEC general wiring entrance applications. Depending on feeder and main service cable applications will determine whether Table 310.15 or Table 310.16 is selected for PV cabling ampacity as a separate power source.
