[RE-wrenches] PV Recombiner

[jay]

I”ll chime in here.

Yes the GSLC is a piece of junk.  
However it is UL listed for the job. And while you could put together something that would work with Airpax breakers together, but it wouldn’t be UL.

What I do is to swap out all the wires to Arctic ultra flex.  This allows much better movement of the wires with significantly less stress on the terminals.   And if you want to not attach wires to the back of the breakers then you can and I’ve seen outback do it, install lay in lugs facing outwards so you can use a screwdriver or allen key on them.  Allows for installation and removal of wire without removal of the breaker or the plate/breakers.  With thimbles of course. And I can’t find them but I know they make them, shields that fit between each breaker so the lay in lugs are insulated.

I just don’t like the design concept that clutters the cabinet with AC and DC breakers that are difficult to access and block other components.  See photo below of a prewired GSLC Cabinet we were asked to work in.  Not a good scenario.

We run all AC leads to adjacent load centers and we try to minimize the DC breakers in the cabinet.  It is our goal to completely eliminate all breakers from the removable dead-front.  I think it is pretty self-explanatory why one would not prefer to make connections in a hard to reach location.
