I definitely wouldn't trust the L meter, the iron core will mess
things up for the meter since it doesn't have the current to actually
"magnetize" the core.

Anyway, the voltage, current and inductance all make sense - if one
assumes that the voltage is phase-phase (typical), the current is line
current (again, typical), and the inductance is in series with no
common connection (again, typical).

Now, is the core 3 seperate cores, or is it 1 core with 2 windows?  If
it's 3 seperate cores, it would be easy to use with single phase,
simply parallelling the different windings for the appropriate/desired
current.  If it's one common core, parallelling any 2 windings won't
do much for you since you'll either be making a common mode choke (and
won't limit current much) or just increasing the effective number of
turns, limiting the current further (by a factor of 4!).

Hi Sean,

The core is shaped like a rectangular figure-8 with all three coils on the central cross-piece. I'll be using Terry's suggestion of measuring V & I with a scope and see what happens.
