I have been told that all of my termination (rack, patch panels and hubs) equipment will be in a room that has an electrical transformer hanging from the ceiling on the opposite side of the room approximately 8' from the top of my rack.|
What is your recomendation for spacing?

There are separation rules described in EIA/TIA-569 standard. They don't
refer transformer itself as a greatest potential source of troubles but rather power
lines that feed the transformer. It is not quite clear but anyway, the biggest separation distance, described there is ~2 feet for 5kVa 480V power lines. That's why it's pretty
safe to set you termination equipment is about 8 feet apart from the transformer.
These separation issues are described in our guide:
Guide to Separation of Network Cabling from EMI sources. You can take a
look at it on our e-books page here:
Good luck with your installation!
