Scott,
why do you and most others who draw motor control schematics continue to show 3 overload contacts? Few starters have 3 overload contacts in the control circuit.

In the old days, there were only 2 heaters, and therefore only 2 sets of NC contacts in series in the control circuit. As long as I've been at it, however,(18 yrs.) there have been 3. I think in the 60s & 70s, three became the norm.
