Our two Z4000 transformers have one throttle dedicated to each TIU fixed input with a bridge to the variable input, i.e., Throttle A feeds Fixed 1 and VAR 1, and so on ...
So two Z4000s feed two TIUs, equal power to each TIU ...
I've tried to insure the loads are pretty much equalized between heavy use tracks (main lines) and no-so-heavy use tracks, like the freight yard, are on the VAR channels, as are a couple of sidings I can turn on and off with the remote.
Works great .... so far ....

If using an older transformer that lacks modern circuit protection, such as a postwar ZW, it is extremely important to place fast-blow fuses or quick-acting circuit breakers in the Hot wire between the transformer and the TIU channel input.
