William, The first time I saw a prototype of the XW system I groaned at the use of QOU breakers. Partly it was for the reason you mention, and partly because the QOU had become a white elephant, not used in our industry since the demise of the APT/Trace Powercenters. QOUs aren't normally stocked at our local SqD distributor, so we would have to carry yet another stock of breakers, besides OBDC and the CBI lines. My comments to the Xantrex techies didn't make any difference, either.

Too bad we can't have a bus bar for plug on breakers. .I emphasized that I would like to see the AC KO a standard distance from the back plane to allow connection via standard offset to an off-the-shelf load center. Never happened... William Miller
