Rheem tankless water heaters, fed with dual 40A 240V circuits,
are driving all the Leviton and other brand dimmers berserk. 
The lighting all dims and flickers beserkly. The Rheem has a
sharp spike at the peaks of the positive and negative cycles;
that is the cause.

The cure is some ferrite chokes on the power feeds. But fields
class was Many Decades ago. I'm trying to decide if I want ones
with an ID that just accepts the #8 stranded, or it doesn't
matter that much if it's a loose fit.

Thoughts?
