[Amps] Another Plate Transformer Question

[Don Lemley]

Thanks Will,

The measurements are: 5 1/2" Height, 4 3/4" Wide, 8" Deep.
The end bells look to be made of some "cast" metal, with the legs being
about 3/4" wide, and 3/16" or more thick.  The connections are made
through
porcelain insulators on each side of the transformer, primary on one
side, secondary on the other.

Thanks,

Don,

What's the height, width, and depth of the core. Also measure the width
of an outside leg. I can ball park the power but without knowing the
wire size, wont be sure whether it's CCS or ICAS, or the exact power.

Best,

Will
