VC & VH Consumer Unit
Instructions/Data Sheet
This Consumer Unit and Hager devices conform with the following standards:
Consumer Unit: BS EN 61439-3 including Annex ZB.
Switch-disconnectors: BS EN 60947-3.
Residual Current Circuit Breaker (RCCB): BS EN 61008-1
Residual current operated circuit breaker with integral overload (RCBO): BS EN 61009-1
Miniature Circuit Breaker (MCB): BS EN 60898-1
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.
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.
Tightening torque values to be applied (Nm)
Switch-disconnector’s: 40A & 63A: 2.8 Nm
Switch-disconnector’s: 100A: 3.3 Nm
RCCB’s 40A & 63A: 2.8 Nm
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
Good workmanship and proper materials must be applied by the installer.
Metalclad units are provided with knockouts for standard 20, 25, and
32mm conduit and large rear knockouts.
Insulated units are provided with breakouts for standard mini trunking.
Rear cable entries should be scored along the weak point with a sharp
knife, and tapped sharply to remove.
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
1.0mm2to 16mm2for outgoing cables
up to 35.0mm2for 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 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)
IP Ratings:
Cable access into the consumer unit 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,
IP 2XC. 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.
Isolate the electrical supply from the consumer unit.
1. Isolate the electrical supply from the consumer unit.
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.

100mm long) making contact
with live hazardous parts
IP4X A probe of 1mm diameter
shall not enter the enclosure
Insulated Unit - Removing and replacing the top wall for top surface cabling
(IP4X using foam inserts; 1mm2- 10mm2 conductors BS6004)
1. Press in with index nger on one end release clip while pressing in with thumb
on the inner release clip repeat on the other and lifting the wall away from the
unit.
2. After xing the unit, to replace and reseal, place one of the foam seal strips in
the underside of the wall feature and the other in the base (behind the cables).
Locate the wall and press down. Additional xing points are provided.

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.

Types of system earthing for which the ASSEMBLY is designed
