You guys know all this stuff. Dave I believe you were running around 12 amps (+ ) total with the 2 Z1000 bricks in parallel?
Posting publicly that you can combine bricks, may lead to some users trying it that maybe don't understand fully the issues. They may not be getting full power to their track for various reasons. So they would attempt to overcome this by cranking up the incoming amps. That may lead to more issues like frying things that are not up to handling the current.
For other readers who come across this post, I feel it is important to state the facts like only 10 amps max per TIU channel when wired normally.
Otherwise run in passive wiring mode. That keeps the TIU channels safe from the higher current.
Sorry for the interruption!
