Important Notes
  This product should be installed,commissioned and Maintained by,or under the supervision of,a competent Electrician in accordance with current electrical Engineering Codes of practice,IEE Regulations for the Electrical Equipment of Building,Statutory requirements,and any specific instruction issued by the Company.After completing the installation and testing of this product it is essential that this leaflet,If is drawn to the attention of the person responsible for its future operation and maintenance,and is at all times available for ready reference.
  These notes assume throughout that the product is disconnected from the supply. it is essential that is done before any work is carried out.
Overcurrent Protection
  Over current protection to circuit conductors is provided by thermal and magnetic
tripping elements is the line side,equivalent to the mcb.Operating characteristics on
overcurrent(the time/current curves)are as for the standard MCB.This section of the unit
complies.with the requirements of BSEN6094-2for miniature circuit breakers.Short circuit
requirements comply with Bs4293.
Earth Fault Protection
  The RCD element of the device provides core-balance detection of the difference between line and neutral currents and amplification to provide high seneitivity.
Operation of The Test Button
  This check is made after installtion with all shields and covers in place,and requires the MCB-RCD and the main supply switched on.Pressing the button marked`T¨on the MCB/RCD applies a simulated earth-fault to the MCB/RCE which should trip instantly.
  This should be checked frequently,at least quarterly,If the MCB/RCD falls to trip,seek for expert advice.
  Operation of the test device checks only the corrent functioning of the MCB/RCD at a higher current than the rated tripping level.This test does net check the integrity of the earthing system.
Installation
  The BLACK flying neutral supply lead must be connected to the Neutral supply terminal block.
  The LOAD connections are made to the outgoing terminals of the unit marked`L¨LOAD and N LOAD.
NOTE:The neutral of the load MUSTNOT be connected to the Neutral Supply terminal block UNIT IN CIRCUIT.TO CARRY OUT HV TESTS DISCONNECTLOAD SIDE CABLES FROM MCB/RCD UNIT AND TEST CIRCUIT AS NORMAL.
  After installation check the operation of the unit as specified in the IEE Wiring Regulations.Since this will require the unit to be energised.all shield and covers must be replaced before performing these tests.
