<DIV><SPAN class=031232601-06122008>Wait a minute...I may be wrong here, as I
have become the "graybeard guy who handles off-grid and weird stuff" at Positive
Energy, but I think the 2008 Code allows 120% for commercial, not just
residential, as long as it is fed at the bottom of the bussbar. 2011 NEC is
trying to make it a bit less confusing by adding a set of
alternatives.</SPAN></DIV>

<DIV>A line tap typically occurs between the utility meter and the main breaker
- not after the main breaker on the load side. It seems that you are describing
a load side tap which follows the 120% rule under 2008 NEC; I might be
misunderstanding the situation. Please clarify. There are few folks out there
who are able handle these large commercial grade interconnections and I think it
is well worth discussing.</DIV>

Miller<BR><BR>>Wreches,<BR>><BR>><BR>>I have a system where we are

breaker using the existing bolts.<BR>><BR>><BR>>The inverter and
utility fused disco are about 200 ft away, and the tap <BR>>conductors travel
about15ft in EMT conduit before leaving the <BR>>building. After that the
circuit is outdoors. NEC 240.21(B)5 allows taps <BR>>of unlimited length for
conductors located outside of a building, except <BR>>at the point of load
