hager VMLF114 14-Way Main Switch Flush Consumer Unit Instructions

hager VMLF114 14-Way Main Switch Flush Consumer

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 specified 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.
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 leaflet is provided overleaf. This leaflet should be left for the end user.
Single conductors below 1.5mm 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)

For guidance when making connections in a consumer unit electrical safety first /BEAMA document “Guidance for installers when making connections in consumer units” is available from
hager.co.uk/63026.htm
Cable Access:
Cable access into the metal consumer unit must maintain the integrity of the non-combustable 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:
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 specific need for external fire 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 fire rated cable glands or external intumescent sealing should they consider necessary. Internal intumescent pads shall not be used.

Rated insulation voltage (Ui)

320V a.c. 50Hz

Rated impulse withstand voltage (Uimp)

4kV

Rated current of the Assembly (InA)

100A, 63A

Note : Dependent upon rating of main incoming device

Rated current of an Outgoing circuit (Inc) Circuit next to an RCCB: MCB & RCBO 6-50A (marked rated current on device)

All other circuits MCB 6A – 63A (marked rated current on device) All other circuits RCBO 6A – 50A (marked rated current on device)

| Rated current of outgoing unit (Inc)

RCCB 80A (marked rated current on device)

Rated conditional short-circuit current of the ASSEMBLY (Icc)

Annex ZB: 16 kA rms at 250V, power factor 0.6 with equipment and arrangements specified in Hager’s technical documentation / catalogue.

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 **** Note: RDF only applies to continuously and simultaneously loaded 1way = 1.0 circuits.

2way – 3way = 0.8

4way – 5way = 0.7 In principle, this means adjacent circuit-breakers having a load

6way – 9way = 0.6 ‘on’ time exceeding 30 minutes or where a load not exceeding 30

10way and above = 0.5 minutes has an ‘off’ time less than the ‘on’ time, will need to have the rated diversity factor applied as indicated.

Rated frequency (fn)

50 Hz

Pollution degree

2

Types of system earthing for which the ASSEMBLY is designed

Fitting Hager MCBs and RCBOs:
Only equipment and arrangements specified 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, by loosening the two captive screws.
3. Fully slacken the lower terminal of the device.
4. Fully open the bottom device clip (fig 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 firmly onto the busbar, fully tighten the lower terminal screw.
8. After fitting 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.
