I have the following question:

We have a rack at a datacenter with a 208V/60 amp circuit coming into a 208V/60 AMP PDU and I was wondering if we lower the circuit to let say 208V/30 amp or 120/30 amp do I need to change the PDU to a 208V/30 or 120/30 as to match the amperage on the circuit?

I guess my question is if the PDU has to always match the amperage and volts of the circuit?

Thanks in advance

Voltage has to match, amperage has to be less than or equal (but with some margin to spare).

It doesn't need to match no, all you're doing is potentially moving which part will trip out first.
