This is a thin double 20A breaker.
Small type on the breaker: 2 pole, issue # LK-4137

small print)

It's 3/4" thick for the 2 switches, and 4-5/8" wide.

Huh? Is it a breaker with two 20A switches that fit into one slot of the
breaker box? The switches are _not_ tied together, and they do not
trip/turn off and on at the same time, right? This has to be the case if
the breaker is 3/4" thick with two switches on it...

If so, then you do _not_ have a 2-pole breaker (which is normally used
for 220V circuits). You have a compound single-pole breaker.

Anyway, if this is the case, we have been addressing the problem totally
wrong (so throw out _everything_ that's been said), so please confirm.
