<DIV dir=ltr align=left><SPAN class=734410122-12012011><FONT color=#0000ff

690.14 (D) also have to comply with or be counted in with 690.14 (4) and
(5).</FONT></SPAN></DIV>

<DIV dir=ltr align=left><SPAN class=734410122-12012011><FONT color=#0000ff
size=2 face=Arial>690.13 and 690.14 are pretty confusing in the use of the term
disconnect. Which sections apply to the disconnecting DC PV source circuits and
which sections apply to AC PV system circuit, which to both? Can the switches
integrated into some inverter by the manufacturer be regarded as the disconnects
required in these sections?</FONT></SPAN></DIV>

<DIV dir=ltr align=left><SPAN class=734410122-12012011><FONT color=#0000ff
size=2 face=Arial>Here is my take: The fused disconnect in the basement is
the PV system disconnecting means of which there is only one. This switch meets
the requirements of 690.15 "...A single disconnecting means in accordance with
690.17 shall be permitted for the combined ac output of one or more inverters or
ac modules in an interactive system." It meets the requirements 690.14 (C) (1)
Exception so long as you comply with 690.31 (E). You still need additional
disconnects on the roof and labelling in accordance with 690.14 (D), but they
don't have to comply with 690.14 (4) (5) so long as there ac outpust are
routed thru the 8th floor load center and thru the switch in the
basement.</FONT></SPAN></DIV>

<P class=MsoNormal>Hi Wrencher’s<o:p></o:p></P>
<P class=MsoNormal>I am working on a system with 10 inverters. The output
of all 10 single phase inverters will be combined in a main lug only panel
located on the 8<SUP>th</SUP> floor (each inverter will have a 2 pole
breaker). The MLO Panel will be protected by a fused switch located in the
basement. Does the panel on the 8<SUP>th</SUP> floor used to combine all
10 inverters need to have a main breaker in order to comply with 690.14 (4)?
