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

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

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,
