HU361 as Combiner/Disconnect [RE-wrenches]

[Jeff Clearwater]

<x-flowed>
Hi Matt,


Yes I see your points.  I was trying to get away with only one line 
to the SB by combining a the HU361  but if each lug is rated for only 
one cu landing that won't work and it defeats what I was after.

But it strikes me as very odd that a PSSB breaker can be rated to two 
conductors/lug but not the nice big lugs on a HU361.  Any chance of 
that rating changing?  John B?

Thanks,

Jeff C.

My drawing was electrical not orientation - but yes thanks for the 
reminder of using the shieded side correctly.
