Hi Carl,

I've been looking for a scientific answer to gageing the power and
the closest I have found is some vague references to the core area as
a means of knowing the current. I have not found the calculations
that would actually determine the amperage.

But, it seems the consensus is based on wire gauge. since wire
selected has to carry the current, there is no benefit to use thicker
wire as it makes it hard to fit. also the wire has to be thick
enough or it will overheat. so the wire gage is a good place to start.

Not a great answer, but a starting point.
