minimum clearances [RE-wrenches]

[Marco Mangelsdorf]

I've got an install using several SMA 6000s.  I know what the clearances for
the working spaces for electrical equipment are: 36" in front, 30" wide, and
6'6" high. The SB6000 inverters need 8" clearance around them. Does anyone
know what the minimum clearances are as far as mounting an inverter off the
floor as far as the NEC is concerned? Is it 3", 12", 36" or nothing at all?
How about an inverter AC output load center? Same thing as any distribution
panel I would think. I can't find anything to say what the min. or max.
would be off the floor though. I know a manually operated disco handle can
not be higher than 6'7" without some special attachments. I thought there
was a min of 36" for the handle in the off position off the floor. I just
can't seem to find it in the code. Any ideas?

thanks,
