208V/30amp Datacenter circuit question

[boomshakalaka]

Hi everyone, I've been looking around for answers but no one is able to help me so far.

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

not really knowing what a PDU is, but going off general rule on thumb when it comes to electricity, voltages have to match, and supply current must be greater than the need.
