Pull wires through a transformer

[rey-man]

Need help to identify if this is a code violation. Contractor needs to run a feeder through a transformer. The secondary of the xfmr needs to go to a MTS and the wires from the MTS load side will go through the transformer because the conduit stub out is under the transformer. Is this a violation? If we run the wires through a LIquidtight through the transformer, is this allowable?
Any reference in the code is appreciated.
Thanks for the help

Other than Article 70x critical loads, the NEC is relatively silent on what circuits can run through a common enclosure. One hard principle is that service conductors (without effective OCPD) cannot be mixed with non-service conductors.
In your case, the mention of an MTS raises the possibility that 70x loads are involved, so we really need more information.
