Which consequence results when undersized residential circuit breakers repeatedly trip under expected load?

A)Conductor insulation thermal degradation occurs
B)Overvoltage transients damage connected electronics
C)Increased inductive reactance diminishes supply
D)Power factor markedly improves negligibly

💡 Explanation

Repeated tripping from an undersized breaker causes prolonged moderate overcurrent events; because ohmic heating increases with I^2*R, thermal runaway accelerates the insulation breakdown, therefore increasing risk of arcing faults rather than improving power factor or affecting voltage, which result from reactive loads.
