Confused about servo drives

A 350VDC short-to-earth does get very sparky and melty very quickly, and would not hurt for very long. So an isolation transformer makes a lot of sense. I might even add one.
In the UK we use these on building sites: www.ebay.com/itm/New-3-3-KVA-Site-Transf...ade-Uk-/150420255240
And they are very cheap. However I don't really want to drop the voltage. If they use 1:1 ratio ones in the US then it might be very easy to isolate your power lines.

I thought about it. I'm pretty sure I understand the theory well enough, but everything I ran into online was people flipping out about not using an isolation transformer.
It seems I'd need a 1:1(or thereabouts) transformer able to handle up to 3x10A at 220V or so. I could downgrade a little since all axes shouldn't be going full tilt all at the same time I guess.
