ZW hazards

[Fred Bear]

Bob, if I have isolated blocks assigned to different posts on the ZW, will that alone cause problems? Thanks, Jake

No as long as the outside rail goes to the U terminal on all blocks and the center rail of each block to the ABC or D of the corresponding block throttle.

That is how I've set this up. All outside rails ALWAYS go to the U post on any transformer I set up, with the " hot " side, going to the middle rails. Any danger this way? Thanks, Jake

Yes.  See my reply on the "Grades" topic.
