Who makes an inexpensive tester that I can plug
into 208 V 3 phase L14-30 outlets to determine
phase rotation?

Could you just find a small 3ph motor and use that?


That would be way too easy...

I thought of that. Smallest gear motor I could find
cheaply was 1/2 HP!


Oriental motor makes 3 phase gearmotors as small as 6W. Not cheap new
(around $75 for a motor, ~$150 for a gearmotor) but there are usually
quite a few on ebay.

"SW" in the part number signifies 200/220/230V 3 phase.
