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!

For machine tools usually I just momentarily turn on the coolant pump
before
going any further.

I will have to rearrange my troubleshooting schedule
so that 'rotation direction' is at the top of the list.

I've seen small fans that run on three phase, muffin fans.
