No, the maximum official size is 16AWG which is good for 12A. If you're looking at bringing it up the tower, I'd recommend using a transition terminal block that can handle whatever size wire you're bringing in, and then run a smaller one to the pdu. Bonus reliability points if you use ferrules on the 16AWG wire (assuming stranded wire here).
And, yes, each of the 5 ports have fast overcurrent protection which will, in most cases, shut one port down and leave the others running. The "most cases" is the hedge which covers things like the power supply you're powering the whole thing from having faster overcurrent protection than ours. And cases where the short circuit causes enough of a power supply blip to cause everything else to reset due to the sudden voltage drop in the short period before the overcurrent protection kicks in.
