So while the TPC will accept two transformers or outputs connected in parallel, the Z4000 two outputs cannot be connected together. Dale says there is a fault detected by the Z4000 if you try to do that.
Incidently, I have had my (new) ZW B and C outputs tied together for several years (fed by two PH 180s). The only thing that didn't work about it was trying to address channel 2 or channel 3 under command control to vary the voltage. Often, one address would vary both outputs but it varied as to which address would do it. Then maybe neither one would do it. A short on the track did shut down both outputs. I run command, so I didn't need to adjust them...just was trying it. Emergency shut down worked perfectly however.
I am running it separated now...feels better and I don't think I needed more than 10 amps anyway.
