| Symptom | Likely Cause (per manual) | Solution | | :--- | :--- | :--- | | | Cumulative earth leakage > 30mA. | Use a clamp meter to find leaky appliance (heater, motor, old wiring). | | Test button fails to trip | Mechanical seizure or welded contacts. | Critical: Replace the unit. Do not rely on it. | | Lever won't reset | Persistent earth fault or internal damage. | Disconnect downstream wires. If lever resets, fault is in wiring. If not, RCD is dead. | | Unit runs hot | Loose terminal screws or overcurrent. | Torque to spec (2 Nm). Remember, this RCD has no thermal overload protection (needs an MCB in series). | Merlin Gerin Multi 9 Ic 2000 P Manual
