I combined the AC into a panel of 12 breakers, with one main (i had 12 inverters). For the DC side I did something DT but I could have used 2 each 6 pole Square D 600 volt 30 amp Disconnects or 3 each 4 pole, or 4 each 3 pole to complete the disconnect requirement</DIV>

<P class=MsoNormal>Hi Wrencher’s</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)? </P>
<P class=MsoNormal> </P>
<P class=MsoNormal>Any and all feedback is appreciated.</P>
