Installation Instructions:
All product(s) must be installed by a suitably competent electrician
Giving consideration to their intended use and in accordance with the current edition of BS 7671 (IET Wiring Regulations).
The Electricity at Work regulations and the Health and Safety at Work Act shall be complied with.
Only equipment and arrangements specied in Hager’s technical documentation / catalogue shall be used.
Install in the horizontal plane only.
Important notice:
To prevent potential overheating from loose connections the installer shall check connections are tight to the torque levels stated in these instructions
prior to energizing this board. This check should include factory made connections which may have loosened in transit.
Guidance Notes:
The total load must not exceed the rating of the incoming device or the assigned assembly rating (InA) whichever is the lower. Each neutral and earth
connection must correspond numerically to its outgoing way. Additional blanks (ref. JK01B) are available to cover spare ways.
A pack is provided to label this consumer unit, please consult us for spares or replacements.
Operating Instruction leaet is provided overleaf. This leaet should be left for the end user.
Single conductors below 1.5mm² need to be doubled back in the terminal bar.
Consumer Units incorporating RCDs in TT systems should incorporate an S type (time Delayed) RCCB, e.g. 100 mA s-type RCCB . Alternatively a main
switch with RCBO protection on all outgoing circuits should be used.
Precautions need to be taken to prevent faults to earth on the supply side of the RCD (as per BS7671 regulation 531.4.1)
For guidance when making connections in a consumer unit electrical safety rst /BEAMA document
“Guidance for installers when making connections in consumer units” is available from
hager.co.uk/63026.htm
Cable Access:
Cable access into the metal consumer unit must maintain the integrity of the non-combustable
consumer unit so far as reasonably practicable. This can generally be achieved by the installer
ensuring that cable access holes they make in the enclosure do not to leave gaps greater than:
· 2.5 mm for all other surfaces of the enclosure that are accessible after installation.
For rear cable access, the minimum number of knockout(s) shall be removed.
Tests on hager consumer units have indicated that there is no specic need for external re rated
cable glands or intumescent sealing in addition to the guidance below, with respect to achieving a non-combustible enclosure.
However this does not preclude the designer/installer from using re rated cable glands or external intumescent sealing should
they consider necessary. Internal intumescent pads shall not be used.

circuits.
In principle, this means adjacent circuit-breakers having a load
‘on’ time exceeding 30 minutes or where a load not exceeding 30
minutes has an ‘off’ time less than the ‘on’ time, will need to have
the rated diversity factor applied as indicated.
Warranty
This distribution board is offered with a 24 month warranty against defective material or manufacture. If a warranty claim is necessary, please
call the technical support number given at the bottom of the page and we will be pleased to help.
