BEP Marinco RCD20A30MA Breaker Instruction Manual

1. Rhagymadrodd

This manual provides essential information for the safe installation, operation, and maintenance of the BEP Marinco RCD20A30MA Residual Current Device (RCD) Breaker. This device is designed to protect against electric shock by quickly disconnecting the circuit when it detects an imbalance in the electrical current, indicating a leakage to earth.

Please read this manual thoroughly before installation and keep it for future reference. Proper installation and adherence to safety guidelines are crucial for the effective operation and longevity of the RCD breaker.

2. Gwybodaeth Diogelwch

RHYBUDD: Electrical work should only be performed by qualified personnel. Failure to follow these instructions can result in serious injury, death, or equipment damage.

• Always disconnect power before installing, servicing, or removing the RCD breaker.
• Sicrhewch fod yr holl weirio yn cydymffurfio â chodau trydanol lleol a chenedlaethol.
• Peidiwch â defnyddio'r ddyfais hon os yw'n ymddangos wedi'i difrodi.
• This RCD is designed for specific current and sensitivity ratings. Do not exceed these ratings.
• Regularly test the RCD as per the instructions in the Maintenance section.
• Protect the device from moisture and extreme temperatures unless specifically rated for such conditions.

4. Gosod a Gosod

Before beginning installation, ensure the main power supply to the circuit is completely disconnected and verified as de-energized.

Camau Gosod:

1. Mowntio: Select a suitable, dry, and protected location for mounting the RCD breaker. Ensure adequate ventilation and accessibility for future maintenance. Secure the breaker using appropriate fasteners through the designated mounting holes.
2. Gwifrau:
   • Connect the incoming live (phase) wire to the 'L' terminal and the incoming neutral wire to the 'N' terminal on the input side of the RCD.
   • Connect the outgoing live (phase) wire to the 'L' terminal and the outgoing neutral wire to the 'N' terminal on the output side of the RCD, leading to the protected circuit.
   • Ensure all connections are tight and secure to prevent loose contacts and overheating. Use appropriate wire gauges for the 20A rating.
3. Dilysu: Double-check all wiring connections against the circuit diagram. Ensure no bare wires are exposed and that the RCD is correctly oriented for current flow.

5. Cyfarwyddiadau Gweithredu

The BEP Marinco RCD20A30MA operates automatically to detect and interrupt earth leakage currents. It does not require manual operation for its primary protective function.

Gweithrediad arferol:

• When power is supplied and no earth leakage is detected, the RCD will remain in the 'ON' (closed circuit) position, allowing current to flow to the protected circuit.
• In the event of an earth leakage fault exceeding 30mA, the RCD will automatically trip to the 'OFF' (open circuit) position, disconnecting the power supply to prevent electric shock.

Resetting the RCD:

If the RCD trips, it indicates an earth leakage fault. Before resetting, identify and rectify the cause of the fault. Once the fault is cleared:

1. Ensure the power to the affected circuit is off.
2. Push the RCD lever fully to the 'OFF' position.
3. Then, push the lever to the 'ON' position to reset the RCD.
4. If the RCD trips again immediately, the fault has not been cleared or there is a persistent issue. Do not attempt to reset repeatedly without addressing the underlying problem.

6. cynnal

Regular testing of the RCD is essential to ensure its proper functioning and continued protection.

Gweithdrefn Prawf Misol:

1. Ensure power is supplied to the RCD and the protected circuit is operational.
2. Locate the 'TEST' button on the front of the RCD.
3. Press the 'TEST' button. The RCD should immediately trip to the 'OFF' position. This confirms the internal tripping mechanism is working.
4. Reset the RCD by pushing the lever fully to 'OFF' and then to 'ON'.
5. If the RCD does not trip when the 'TEST' button is pressed, or if it fails to reset, the device may be faulty and should be replaced immediately by a qualified electrician.

Beyond this monthly test, no other user-serviceable parts or routine maintenance are required. Keep the device clean and free from dust and debris.
