[RE-wrenches] 690.14 (4) Max Number of Disconnects

[Darryl Thayer]

I had a similar situation in Minnesota, my local inspector was puzzeled but the 
regional inspector said ABSOLUTLY  the solar equipment has to be shut off with 
no more than 6 motions of the hand.  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

Hi Wrencher’s
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 8th 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 8th floor used to 
combine all 10 inverters need to have a main breaker in order to comply with 
690.14 (4)?   
 
Any and all feedback is appreciated.
