RCCB’s 80A & 100A: 3.3 Nm
MCBs: 2.8 Nm
RCBO’s: 2.8 Nm
Earth & Neutral terminal bar connections: 2.0 Nm
Single conductors below 1.5mm² need to be doubled back in the
terminal bar
Front metal cover xing screws: 2.0 Nm
Meter torque: 2.4 Nm
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.
Metalclad units are provided with knockouts for standard 20, 25,
and 32mm conduit and large rear knockouts.
Pull and lift the terminal bar support away from the unit resting
the rail supported by the earth strap. After xing conduit/ cable
glands, locate the rail support and press down.
Note: Only BASEC approved cable should be used
1.0mm2 to 16mm2 for outgoing cables
up to 35.0mm2 for incoming live cables
Single conductors below 1.5mm² need to be doubled back in the terminal bar.

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 DBO, 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.
DBOs 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)
IP Ratings:
Cable access into the DBO must maintain the integrity so far as reasonably practicable. In essence, for surfaces accessible after installation,
this means maintaining the requirement for the horizontal top surface of the enclosure to provide a degree of protection of at least IP4X and
elsewhere, IP30. For rear cable access, the minimum number of knockout(s) shall be removed.
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 DBO.
2. Remove the front cover.
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.

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.
