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: 3.6 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

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.

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.
