ately derived system and would not require it's own system ground. At
that point, would the AC side of the inverter still be considered a
separately derived system or would the need for system grounding go away?

Aaron,
Can you give a bit more information? Is this a situation where the meter and
the main disconnect are located on the outside of the building, with a
feeder running to a load center in the garage? Does the utility at this
location require a external lockable disconnect?

Thanks August,
NFPA says there are giving away a softcover copy of 2011 to folks who take a
years subscription to NECPLUS before February something.
Seems like a good value.

Know where to get it?

I assume that the fused disconnect is co-located in the basement with the

they located on the roof?

How do utilites go about adjusting the voltage at any given site? Adjustable
taps on the transformers on the poles? Do they have to go back to the
nearest sub-station? Re-arrange the distrubution of customers across
differenat areas of the grid.
I am in the dark here.

I am wondering if anyone has gotten any info since then.
