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!

I've seen three phase motors down to about 1/10 HP (small fan), but
those are really difficult to locate through any normal US sources.
