Active material. The chemically reactive compound on a battery cell plate. . A representation of the relative thickness of atmosphere that solar radiation must pass through to reach a point on earths surface.
The systems you are installing will be in service for decades or more – and you want components that are built to last. This is particularly true with rooftop PV junction boxes. There is a lot of voltage in these systems, and if your junction box cracks, is damaged, or is otherwise compromised things can get bad quickly. This has been a gray area. The proposed language for NEC 2014 is more clear: 690.31 Methods Permitted (B) Identification and grouping. PV source circuits and PV output circuits shall not be contained in the same raceway, cable tray, cable, outlet box, junction box, or similar fitting as conductors, feeders, branch circuits of other non-PV systems, or inverter .
