Sorry for this OT.

I'm looking for: info, ideas, pointers, etc.

I need to pass 40-60A thru a wire to insure the capacity, but where do I get
this much current without having to use a humungous load to drop the voltage
and control the current.

I thought on using a relatively large power transformer, replacing the
secondary winding with a few turns of really heavy gauge to get a low
voltage (0.5-1V maybe) at a high current.

What do you suggest?

TIA
