removed. The units have multiple xing points that will suit No.8 & No.10 screws

These metal units are provided with knockouts suitable for

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)

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:

· 1.0 mm for the horizontal top surface and

· 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 specic need for external re 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 re rated cable

glands or external intumescent sealing should they consider necessary. Internal intumescent pads shall not be used.
