Control Power Transformers 3kVA and 5kVA should be installed on its own instrument compartment?

Issue:
Control power transformers: 3 and 5 kVA on its own instrument compartment.
Product Line:
Power Zone 4 Switchgear and QED6 Switchboard
Environment:
Power Products
Cause:
Can be installed additional components no associated to 3kVA or 5kVA transformers and primary and secondary protection in same instrument compartment?
Resolution:
Investigated with UL File - Vol SQ section General, Transformers rated 3000-5000VA shall be mounted in a compartment, otherwise empty, of minimum dimensions 21 by 21 by 15 in. so as long as we can meet that min. space for that application, a compartment may be shared with small components that don't protrude that space.
