one more thing, in most cases, "wire size" should always be the
largest you
can get away with (have handy, etc)--not only is it more efficient
(lower
ohmic loss of power) it usually holds form better... I would not be
all
that concerned about capacitance between turns--unless for very high
freq
use...

John, have you ever tried winding the largest possible wire around a
ferrite toroid ring?

Reg:

Yes, I have, started winding 'em with too BIG of wire to, had to drop a
couple sizes... which is why I said:
"...should always be the largest you can get away with...", as to "wire
size."
A 2" core is pretty big though, that is what he has got-if I know those
numbers correctly, and unless he is going to the basement (160M) or a KW
(probably could get by with a KW on a 200A too, but I'd go 2.5" core) he has
some room...
It is a 200A, they have a bit more inductance per turn too (bit fewer turns
for same mh/uh), than just a 200, if I remember datasheets correctly...

Warmest regards,
John
