re Snap-on ferrites as common-mode tester, I've been using
this for some years. Ad hoc test equipment. Great minds must
think alike (heh). However, they don't replace a Solar or
Eaton (or the like) snap-on current transformer -- which
I've got. They are just MUCH less expensive.
I found one of the Palomar current meters on e-Bay, too. Those
are no longer in production. MFJ makes a tunable current probe
using an electrostatic shield around a ferrite rod, too; I've
retuned one for AMBC and used it on telecomm gear near a radio
station.
