I suspect that the handle tie that allows only one pole to trip is not
working as designed. There are handle ties that are retrofitted that do
not trip both poles reliably.

William,
Good points. Keep in mind that both of these breakers have handle ties
(both are two pole), it's just that one can trip independently and the
other forces both to trip. What is the correct solution for 240 V solar
inverters? It seems like common trip is the best way to go but I've not
been able to find any direct reference to this in a brief internet search.
I'm a CA certified general electrician but the test didn't go into this
kind of detail.
