Does anyone have the schematic for an 874-D power controller?
Or better yet, a good used circuit breaker?
At least one of the three (ganged) breakers is internally flaky
and will turn off if the handle is pushed upward all the way to
"ON" (they work if the handle row is carefully lifted just far
enough but obviously that is not reliable).
It looks like the (original-type) Heinemann breakers are available
from Newark, and similar ones from Mouser that will
probably fit,
but they are *very* expensive new...
thanks
