Can a loose connection in the load circuit cause the circuit breaker to trip?
Circuit breakers provide overload protection and short-circuit protection; these are the only two functions they have.
Check where the connection is loose; a loose connection at an outlet can cause the circuit breaker to trip
A loaded virtual connection generally causes a trip, but usually a trip occurs only when a lagoon phenomenon occurs at the virtual connection site.
It generally does not trip, but a loose connection can cause the wires to overheat or spark, resulting in a loss of power in the circuit or damage to the circuit breaker
