Re: Measuring motor current (anyone tried this?)

I was thinking of that, a 3 or 4 foot length of #18 with 1/4" male quick connects on the ends to fit into the PDB - I'd surely get the voltage drop I need there.

And, the wire can act as a fuse

I'm not sure I'll be able to see a speed difference between motors; they are installed two-to-a-gearbox, which slightly complicates it.

Oh yes, and I have only a few minutes to get it done.
