I have never seen a 15 kva transformer with a factory bonded X0 so it would be field installed.

15kva 480V to 208/120V three phase transformer does system bonding jumper and bonding jumper to enclosure provided by manufacturer or contractor has to provide?
Depends on the manufacturer. New ones are now coming with a grounding/bonding terminal bar and a strap connected to the chassis. Some, you have to wire it up yourself. Check with your supplier.

Eh. I just realized how small we're talking. Yeah, not sure on that.

most small transformers I have used of late have a bonding terminal included attached to the sheet metal. but no bonding strap. having thought about it, I find that a little curious since almost always in 120V systems it will be required.
