Product Usage Instructions

Installation

To ensure proper installation, follow these steps:

1. The MINI RCBO must be installed by a qualified electrician in accordance with the current IET Wiring Regulations BS 7671.
2. The total load must not exceed the rating of the RCBO or any additional limitation.
3. The RCBO is designed to fit FuseBox consumer units and modular enclosures.
4. Mount the RCBO on a 35mm top hat din rail, ensuring that the din rail clip at the bottom is pushed in to lock the RCBO onto the din rail. Make sure the lever is in the OFF position.
5. Cut, dress, and connect the cables as shown in the wiring diagram.
   • Connect the Line (Lin) terminal to the bus bar.
   • Connect the Neutral flying lead to the neutral terminal bar (it can be cut to size to suit the application).
   • Connect the load to the L OUT and N OUT terminals at the top of the RCBO.
   • Connect the Load earth to the terminal bar.

Connections

Before powering up the circuit, check that all connections are properly torqued. Loose connections can cause fires.

Testing

After completing the installation, it is essential to test the RCBO in accordance with the latest edition of the IET Wiring Regulations for Electrical Installations (BS 7671).

Operation of the TEST button on RCBO:

• If newly fitted systems do not trip on the TEST button or use an RCD tester, the problem is normally caused by an earth-to-neutral fault on the circuit (PME supply). Installers can check the RCBO by removing the LOAD connections on the RCBO and applying power. If the TEST button works, the fault is in the circuit.

FAQ (Frequently Asked Questions)

Q: What should I do if an RCBO trips?

A: Follow these steps:

1. Reset the tripped RCBO to the ON position.
2. If the RCBO trips again, disconnect all appliances connected to this circuit.
3. Switch the RCBO to the ON position and connect one appliance at a time to see which one trips the RCBO.

Wiring Diagram

MINI RCBO series (RTAM)

• MINI RCBO with switched LINE and NEUTRAL. Used for protection against overload, short circuits, and earth leakage. Type A for AC and pulsating DC sensitivity with a short circuit capacity of 6kA with a maximum rating of 40A.
• Compact in size increasing working space within a FuseBox consumer unit making installation, connection, and testing easier and quicker.
• Flying Neutral cable can be cut to suit but should be terminated.

TESTING:

• Line and Neutral conductors DO NOT have to be disconnected for IR (insulation resistance) if the lever is in the OFF position.

• Lin (Line) terminal connects to the bus bar.
• Neutral flying leads to the neutral terminal bar (can be cut to size to suit application).
• Connect the load to the L OUT and N OUT terminals at the top of the RCBO and the Load earth to the terminal bar.

Connections

• a Before powering up the circuit check all connections are TORQUED.
• Loose connections cause fires!

Testing

• CONNECTIONS TO THE MINI RCBO DO NOT REQUIRE TO BE DISCONNECTED IF THE LEVER IS IN THE “OFF” POSITION.
• b On completion of the installation, it must be tested in accordance with the latest edition of the IET Wiring Regulations for Electrical Installations (BS 7671).

Operation of the TEST button on RCBO

• When newly fitted systems do not trip on the TEST button or use the RCD tester the problem is normally caused by an earth-to-neutral fault on the circuit (PME supply).
• Installers can easily check the RCBO by removing the LOAD connections on the RCBO and applying power. If the TEST button works the fault is in the circuit.

RCBO TEST

• RCBOs ARE MANUFACTURED IN ACCORDANCE WITH IEC 61009-1 AND MUST BE TESTED TO THIS SPECIFICATION USING A CALIBRATED TEST METER.

General type

• In RCBO will not trip
• In RCBO must trip within 300ms
• In RCBO must trip within 40ms

What to do if an RCBO trips

1. Reset tripped RCBO to ON position
2. If RCBO trips again then disconnect all appliances connected to this circuit.
3. Switch the RCBO to the ON position and connect 1 appliance at a time to see which one trips the RCBO.
4. Once the faulty appliance has been identified, DO NOT USE the appliance until it has been checked.
5. Switch RCBO to the ON position.
6. If the fault is not clear phone a qualified electrician to check the installation
