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 specied in Hager’s technical documentation /
catalogue shall be used.
Install in the horizontal plane only.
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
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.
Good workmanship and proper materials must be applied by the installer. The cable
entry method shall, as far as reasonably practical, maintain the non-combustable
arrangement of the enclosure. Account shall be taken of these instructions.
For guidance on RCD selection, AFDD selection and more, see the related BEAMA
guide in our BEAMA guide web page - hager.co.uk/18thedition.
The units have multiple xing points that will suit No.8 & No.10 screws
These metal units are provided with knockouts suitable
for use with 100x50mm trunking, 50x50mm trunking
and also large rear knockouts.
Rear cable entries shall enter thorough selected rear Knockout; once
the Knockout is removed apply the appropriate cable entry plate (full
list on page 4). Cable entry plates are available to clip into the knockout
hole and provide a safe edge to bring cables in.
Note: Only BASEC approved cable should be used 1.0mm

entry plate
( )VM02CE
Allows cables to enter the rear of the board
without the risk of damage from sharp
edges.
Cable clamp

Installation Instructions / Data Sheet
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. ) are JK01B
available to cover spare ways.
A pack is provided to label this consumer unit, please consult us for spares or
replacements.
Operating Instruction leaet is provided overleaf. This leaet 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)
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:
· 1.0 mm for the horizontal top surface and
· 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 specic 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.
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.
For dimensional information and weights please consult the Hager
catalogue.

Fitting Hager MCBs and RCBOs:
Only equipment and arrangements specied in Hager’s technical
documentation / catalogue shall be used.
1. Isolate the electrical supply from the consumer unit.
2. Remove the front cover, by loosening the two captive
screws.
3. Fully slacken the lower terminal of the device.
4. Fully open the bottom device clip (g 1.)
5. Locate the device onto the din rail, and busbar. Ensure
that the busbar tooth is within the device terminal cage.
6. Close the bottom device clip.
7. While holding the device rmly onto the busbar, fully tighten the lower
terminal screw.
8. After tting all outgoing devices and connecting all outgoing cables,
please check the tightness of all cable connections. This should
include all factory made connections, which may have loosened during
installation or transit.

Selection of RCDs
Different types of RCD exist, depending on their behaviour in the presence of DC
components and frequencies.
Overload protection of switches and RCCBs
This can be achieved by;
Method 1
Ensure the sum of the rated current of the downstream MCBs do not exceed the
rated current of the switch or RCCB (I
nc). This method would however need to
consider the consequences of any spare ways and later additions.
Method 2
Ensure that the rated current of a switch or RCCB (I
nc), stated by the assembly
manufacturer, is not less than the rating of the upstream OCPD. For a domestic
installation this could be a 100A cut-out fuse.
Method 3
Select a consumer unit or distribution assembly that only utilises RCBOs on
outgoing circuits. Consideration will still need to be given as to the rated current of
the main switch.
For more information on these subjects we have made the relevant BEAMA guides
available on our 18th edition hub on our website at hager.co.uk/18thedition

Protection against electric shock
Consumer unit shall be installed in an electrical system conforming to the current edition of IEC 60364 / BS 7671
Rated diversity factor (RDF) / Values of assumed loading
1way = 1.0
2way – 3way = 0.8
4way – 5way = 0.7
6way – 9way = 0.6
10way and above = 0.5
Note: RDF only applies to continuously and simultaneously loaded
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.
