At a job location we recently had a conversation on providing viewing / inspection windows on our transformers at a facility,  the client has a great PM plan is place for all the electrical equipment. Test , cleaning and IR scanning with a FLIR scanner on all major equipment.
I would like to provide any references or code requirements that may support this effort to install the
Viewing / inspection windows. It’s a costly expense and would like to back it up with references.
NEC , NFPA, NFPA 70 E, IEEE or any other references that may apply.

I appreciate your assistance in this matter.
