All breakers have torque specs and the recomendation is to torque them then
retorque then in a hour or so. This takes care of any "cold flow", that is
the soft copper mioving around after it is put under pressure.

It is not limited to CBI breakers, I wish i had a nickle for every breaker
that I ever found with a loose wire in a box!
