[RE-wrenches] 690.31E (through a building)

[Mark Dickson]

Thanks for the reply William!  We will be running it through a fused
combiner at the array prior to that-this would not allow us to disconnect
under load, however I cannot see the need to. . .

 

Best regards,

Mark:

If it were me, I'd put a disconnect prior to entry to the building.  How are
you going to service the connections without a disconnecting means?

Hello there, 
Due to a lot of concrete and asphalt, we are forced to run our PV source
circuits in through one exterior wall, through a crawl space and out through
the opposite exterior wall to our inverter and disconnect.  We will be using
EMT and will not be making any stops while inside the building.  We will
however need to place a couple of pull-boxes due the various required bends
in excess of 360*.  Will we be required to place a DC disconnect at the
"first readily accessible" point inside the building?
