I see that now (it's in post 9).The install described is 12-3 Romex - two ungrounded and one grounded.

But it also causes the breaker's handle to move to a middle position (i.e., between ON and OFF ). That may or may not cause the other breaker's handle to move far enough from it's ON position to turn off the second pump.
Exactly!!!!!!!!!then a bunch of hand wringing ninnys finally got their way and 210.8(B) ruined every generation of electricians that came after it.
Yes that cable assembly is 12/2/2 or 14/2/2.Question for the membership. The word "romex" has been interpreted by those who have posted replies as meaning two ungrounded conductors, one grounded ("neutral") conductor, and one EGC. Is that necessarily true? Could this romex run have included two neutral conductors? I just want to pin this detail down before the OP needs to take any corrective measures.
None, someone working on it is only reason for the rule.I absolutely agree that this is a safety issue if someone is doing electrical work on the circuits. I specifically mentioned the issue of being shocked by the neutral with only one of the two breakers off.
I absolutely agree that this is a violation of current code. Thanks tthh for providing the date of the change.
But what is the safety issue if electrical work is not being done?

Never seen a QO or Homeline do that. May be some chance but risk is pretty lowOnce the installation is made code compliant, that may not be true. The code required handle tie may open the second breaker if the first one trips.
An engineer from one of the major breaker manufactures told me that for two single pole breakers it is about 30% to 40% of the time, and for three single pole breakers it is almost zero.Never seen a QO or Homeline do that. May be some chance but risk is pretty low
