A different Transformer Phasing question

J jcstrainsOGR Forum Member

I’m a new forum member but a long time lurker with a Transformer phasing question.

 

I’m familiar with transformer phasing as I have 2 heritage ZWs, one MRC Dual Pure Power and one new ZW (with 3 bricks) that are correctly phased.  All are plugged into the same polarized  power strip.

 

However, I just purchased a Z4000 and upon plugging it into the same power strip, it is NOT in the correct phase with the other transformers (based on the polarized plug).

 

It’s not about turning the plug around as to the wider blade as you would need an adapter plug.

 

So, is this a wiring error by MTH or are their Z4000’s just wired differently?

jcstrains,

   There actually were some Z4K's that got out of MTH that seem to have been wired with a different phase set up, they were early transformers as to my understanding, and some have recently shown up as resales.  I actually got to see one of these transformers on a layout a few years back, we used the old style adapter plug on her.  I always advise the people I am helping to make sure their transformers are in phase, no matter how old or how new the transformer happen to be.
