Hello NEC forum,
I'm building PV panels and want them to meet or exceed all applicable specs (UL 1703, NEC 690, IEC, ...).
Right now, I'm focused on US specs.
I thought copies of the text of at least the NEC specifications would be free or cheap, but haven't been able to find it yet.
Also, I thought I might be able to find UL specs, such as UL 1703 for free too, but I realize UL is a for-profit company. I just thought they made their money by testing products for safety, not for letting you know the criteria of their testing.
Any help on CHEAP or FREE sources of NEC, UL, and IEC specs is greatly appreciated.
I can't believe a PDF from ul.com is worth $400.
Thanks,
Mark
