Which consequence results when sustained overload occurs exceeding a Ground Fault Circuit Interrupter (GFCI)'s rated current in a residential circuit?

💡 Explanation

Overload beyond rated current causes increased `resistive heating`, because electrical power dissipation is proportional to the square of current via Joule's Law; therefore, cable insulation degradation poses a fire hazard rather than reducing nuisance trips or magically regulating voltage.
