Dear Readers,
I’ve a 220 water pump for the house that, when I trace back to the
main circuit breaker box, is connected to two (2) individual 15Amp
breakers located immediately adjacent to each other (one on top of the
other). I confirmed that tripping any single one will still leave a
live 110 feed to the pump. This is obviously not safe and I suspect I
need to either: connect the two breaker throws together (if such an
add-on connector exists), or purchase a double wide breaker with two
poles (if such a breaker exists). Do either of these "solutions"
exist?

All advice appreciated.
Thanks.
