It seems as if the above 32VDC market hasn't been significant enough to get the same recognition.
A bit of thread drift:
The last time our USCG rep visited us I asked him specifically about the "above 50V" specifications in the CFRs and the ABYC standards. Specifically, would they apply to a nominal 48VDC system that would charge to well over 50V?
He said that the over 50V category was only meant to address AC installations. I thought this was strange, why not say so in the regs? It's not like anybody is running 55VAC house loads...
