During a workshop assessment, the reported condition is: Residual-current protection trips when a damaged appliance is connected, but the branch overcurrent breaker does not trip. What does this pattern suggest?
Answers
Athe appliance is drawing exactly zero current
Bleakage to earth may exist without enough line current to operate the overcurrent breaker
Cthe overcurrent breaker has increased insulation resistance
Dthe residual-current device measures only voltage
