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)

Fitting Hager MCBs and RCBOs:
Only equipment and arrangements specied 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.

Cable Access:
Cable access into the metal consumer unit must maintain the integrity of the noncombustable 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 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.
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 (Inc). 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 (Inc), 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.
