Correct, but the problem with the device you linked too is that you max out the "whole" PDUs urrent rating, Unless the whole device is rated at 32amps
per phase, and not the
whole device, which is highly unlikely, thus you need to split the devices plugged into two separate PDUs, as to not trip the devices over current protection.
Actually (re-reading the specs), it is 16 amps per phase: which would only draw 32 amps in the degenerate case where two phases are loaded with one unloaded. But that is still less than 20 Amps per phase..
