- Do NOT set up without prior training.
- Must plug DIRECTLY to 10mA RCCB/RCBO
- Always test before use.
a. Red LED should blink for an instant
b. Only the 10mA RCCB should trip
- All other RK electrical connections will be connected to this bar.
The rightmost button has been converted to a test button where the socket live is connected to the earth line by a red wire to simulate a faulty appliance. If pressed, the red LEDs will blink for an instant and only the 10mA RCCB/RCBO will trip, not the 30mA onsite breaker.
