becoming an inter-tie system [RE-wrenches]

[Jeffrey Wolfe, Global Resources]

Hi Larry,

Trace does call for a 12" x 12" box for mounting the GFI, to provide proper 
wire cramming (I mean bending) space. While the accessible face cover is 
nice in some ways, we like it in a screw closed blank faced box to avoid 
untrained access. "Out of sight...)

<<File: ATT00002.htm>>
Wrenches, I have a system on a customers house that consists of 4 SP75's 
roof mounted, a 4024 with a DC 250 disconnect, a C-40 charge controller and 
8 T-105's.  This is a grid connected house and we set up a separate 
subpanel for the loads that run off the 4024.  The grid feeds AC1 and acts 
as the back up.  Therer is no generator on this system.  This system was 
always intended to grow as the customers budget could afford.  Now we are 
adding 12 more SP75's on the roof and they are going to inter-tie with the 
grid.  We will add an outside disconnect to comply with requirements.  The 
question is about GFI protection for the roof mounted array.  What has 
anyone been doing to provide for GFI protection for roof mounted arrays? 
and where in the control room equipment has anyone mounted the GFI 
protection?  There is a 60 amp DC breaker mounted in the DC250 from the 
array on the way to the C-40
Thanks for any feedback
