I'm I required to bond a transformer that is part of manufacturing equipment?

[necnotevenclose]

I'm working on a project that has a manufacturing piece of equipment that has a integral transformer that converts 480V to 208V. The question I have is do I have to provide grounding & bonding for this like I do for a standard
Transformer?

Grounding yes, your likely to find the factory installed the jumper but check the schematics or test for continuity between neutral and ground.

I'd say more information needs to be presented!

But 450 starts Transformers and Transformers Vaults

I'd read right throught to 450.3(B) and the Exception pushs over to 430.72(C)(1) through (C)(5) which may or may not be any help.

If they are for industrial controls than 409 could be a good read, and includes a push over to 670 industrial machinery.

I'm going to go out on a Limb and say that its a branch service, protected infront by a rated disconnect, thus bonded with a ground wire.

If you mean the frame of the transformer, I would think it's already bonded to the supply EGC from the factory. I'm pretty sure that's not what you mean, though.

If you mean the neutral point of the 208v secondary, and presuming it is a Y secondary, I'd say it's part of the equipment, the manufacturer either did or did not bond it for a reason and I wouldn't alter their design, and if the power is not leaving the equipment, it doesn't otherwise matter.
