ThePIP Modular System – Individual Circuit Isolation
When any of ThePIP modules reaches a temperature of 85°C ± 5° the component closes allowing a small short term leakage current to flow to earth. This will cause the RCBO to operate and isolate the circuit supply. The earth leakage current is clamped to a maximum of 6mA i.e. A level not sufficient to raise the touch potential of any metalwork to a dangerous level but allowing the fault to be recorded (any periodic fixed wire test would indicate a lower than expected voltage insulation reading on the circuit, prompting investigation).
Remember the neutral bar and line connections are both at risk from HRC, so monitor them both.
