Have a 480/277Y panel however the neutral is unused. The panel input is three wire plus ground from a delta to wye transformer, the neutral is bonded to ground at the transformer.

So what would you install as a receptical off this panel, a L16-20 or an L19-20. My thinking is the L16 as the neutral doesn't exist.

If the load requires no neutral, I agree with your reasoning: use the right configuration for the circuit: the L16.
