I am in the process of building a power supply for my lathe and need a big
transformer for for the powersupply. My main question is given the type of
transformer I was not sure how the transformer performs with two hot legs as
opposed to one hot and one neutral. I am having a hard time finding a

As Gene already mentioned, why are you looking for a transformer at
all?
The split in split phase means that you can connect loads between
either hot and the neutral to get half of the overall voltage. So if
you have 240V line-to-line, you will get 120V line-to-neutral.
I can think of two

Transformers typically don't care if they are connected between a
neutral and a hot lead or two hot leads.

That will work just fine.
One minor quibble with your drawing. On the secondary
of the 2.5kVA transformer you marked one terminal as 0V
and the other as 110V. That implies that you are grounding
the 0V terminal. Usually if you are rectifying to make
a DC supply, you don't ground either side of
Yes that is just in respect to what the transformer is labeled.

Hi all, i need to compare 4 inputs into hal (a limit value on each of 4
motors) and if one of them is true the output will be true. (it is a
tetrapod, so only one motor-limit at a time can be true, fisically.)
The fastest way in my mind is to use 3 or2 components, so i compare two
