Technical information
1a METAL consumer unit must be installed by a qualified electrician in accordance with the current IET Wiring Regulations
BS 7671
1b Total load must not exceed the rating of the incoming isolator or any additional limitation.
1c The total sum of the individual MCBs may exceed this value where there is appropriate diversity in the installation.
1d The Consumer Unit and associated components have been manufactured to the following specifications:
Standards (TABLE 1)

IP RATING
IP2XC
1e Ambient Temperature: MCBs are calibrated at 30°C according to the calibration temperature requirements of EN60898. At
other temperatures the following rating factors should be used:
At 60°C 0.85 At 20°C 1.0 At 0°C 1.15
1f
Adjacent thermal-magnetic MCBs should not be continuously loaded at their nominal rated currents when mounted in
enclosures.
We recommend a 60% de-rating factor is applied to the MCBs nominal rated current where it is intended to
load the MCBs continuously
2 Enclosure Mounting
2a Remove front cover.
2b Remove
minimum
appropriate
knockouts with a punch, in order to maintain the IP rating and fire containment of the
enclosure we recommend glands are used.
2c Fix base to wall using screws and rawl plugs as appropriate
and remove any debris from inside the consumer unit
.
2d Adjust to the square.
2e Route incoming cables to desired positions.
3 Connection of Tails
3a Cut and dress the main incoming cables and earth conductor.
3b Connect into the appropriate terminals

(3) on RCD, earth terminal bar and torque (TABLE 2).
4 Connections
4a Cut, dress and connect circuit conductors to appropriate MCB neutral and earth terminals.
4b ALL CONNECTIONS (including factory made connections) MUST BE TORQUED (TABLE 2).
4c
Make sure that each earth and neutral outgoing circuit is correctly made to the corresponding numbered terminals as
this will ensure final testing and fault finding is easier.
5 Circuit Identification
5a All circuits must be clearly labelled on the front cover.
6 Enclosure Earthing
6a
An earth cable is supplied in the accessory pack which must be fitted between the front cover and the earth terminal bar
for earth continuity.
7 Operation of the TEST button on RCD
7a When newly fitted systems do not trip on the TEST button of the RCD or using the RCD tester the problem is normally
caused by an earth to neutral fault on the circuit (PME supply).
8 Testing
8a After completion of the installation, it must be tested in accordance with the latest edition of the IET Wiring
Regulations for Electrical Installations (BS 7671).
Before fitting the front cover, check all connections including factory made connections are TORQUED.
Loose connections can cause fires!!!!
