Question about reversing H1 and H2 on Step up step down transformers

[Installer]

H1 and H2 are going across a conduit maybe 300 yards or more. If H1 and H2 of the Step up / Stepdown got reversed because we didn't tone them out, would the physics of the windings change and the transformers behave incorrectly?
This may not sound like a bright question but I got up at 4 am this morning .

No it would not matter. What's the point in stepping up the voltage then reducing it? Are you trying to adjust for voltage drop? You must consider the transformer losses. If you need a voltage drop calculation I can do that for you.

Does not matter. How did someone manage to swap a black wire with a white one?

Just curious why you are grounding one of the 600 V legs.

Must be a heck of a long run to need #6 wire for 8 amps.

The grounded leg should not be fused.

The grounded leg should not be fused.

Almost missed that. It also only has a connection to earth.

And, the center of the secondary winding of the downstream transformer (neutral connection) should also be grounded.

It would not matter for typical 600V class transformers.

It absolutely would be a problem for higher voltage 'single bushing' transformers. Typical distribution transformers are designed with 1 high voltage terminal and one _grounded_ terminal on the primary. The transformer magnetics wouldn't care about the polarity swap, but the insulation system would have something to say as the magic smoke came out....

Note one could use the exception in 250.30(A) to use the grounded conductor as the bonding conductor/EGC, like a service. Basically Bond both ends, and skip the EGC, saves a conductor.

Just curious why you are grounding one of the 600 V legs.

For the most part I think the consensus is grounding 600 volt or less systems is preferred to going ungrounded and using ground detectors. Also allows of the use of that exception I mentioned in the previous post.

This one got solved here a few months ago. Some of you provided guidance. Thank you very much everyone
