Ungrounded Delta Secondary - Bonding

[rcontreraspe]

Does a transformer with an ungrounded delta secondary need to be bonded to CWP or building steel?

The only thing different between a grounded and ungrounded secondary is that the ungrounded one will not have a system bonding jumper. All of the other grounding and bonding rules are the same.
