I am aware of this. But then I have a single 120@20 vs a single 240@20.

With my setup I have 2×120@20 always available, and 240@20 for the occasional welding.

I could assign a different 120 phase to every other outlet but then I would need some clear identification.

The two phases are assigned to the top and bottom outlets the same way all around the shop. If I need to run two high amperage machines, I only have to remember to use one bottom and one top outlet.
