BEP Residual Current Device

For installations in Australia and New Zealand to comply with AS/NZ3004, an approved double pole mains circuit breaker must be mounted upstream of the BEP control panel in the form of an RCD or MCB. A residual current device is designed to disconnect a circuit whenever it detects an imbalance between the energised conductor and the return neutral conductor. Such an imbalance can be caused by current leakage through the body of a person who is grounded and touching an energised part of the circuit. A lethal shock can result from these conditions. RCDs are designed to prevent electrocution by detecting the leakage current, which can be far smaller (typically 5-30 milliamperes) than the currents needed to operate conventional circuit breakers or fuses. RCDs are intended to operate within 25-40 milliseconds, before electric shock can drive the heart into ventricular fibrillation, the most common cause of death through electric shock.
N.B. Must be installed by a licensed electrician.
