Cablelink Plus Modular Floorbox
Load Testing
Load Testing of floorboxes to BS EN 50085 Part 2-2 (Clauses 10.5.103 and 10.5.104).
The floorboxes have been tested to and comply with the loading requirements of BS
EN 50085 Part 2-2 (Cable trunking systems and cable ducting systems for electrical
installations Part 2-2: Particular requirements for cable trunking systems and cable
ducting systems intended for mounting underfloor, flushfloor, or onfloor).
There are two loading criteria for the floorboxes - one with a point loading to replicate
foot traffic for example, and the other, with a large plate to replicate hand trucks / trollies
and heavier larger loads. For both loading criteria the maximum allowable deflection
under load is 6mm and the maximum permanent deflection after the load has been
removed is 3mm. The loading position is the centre of the lid.
The Lid Deflection (loading) graph shows that the maximum point loading
classification achieved is 3kN and the maximum large plate loading classification
achieved is 5kN.
The Permanent Deflection graph shows the permanent deflection from the test
wheel loading at 3kN is 0.55mm and large plate loading at 5kN is 0.4mm.
This is well within the maximum allowable deflection of 3.0mm.

Installation
Cablelink Plus Modular boxes should not be
installed in the following situations:
l
Where protruding electrical cables are likely
to cause a safety hazard
l
In passageways, especially where trolleys or
other vehicles may be used
l
On escape routes, as this may impede the
evacuation of the occupants from the building
l
Where the cleaning methods employed result
in the formation of pools of liquid or soaking
of the floor surface
l
Desks, chairs, shelving, filing cabinets should
not be positioned on the floorbox as this will
interfere with opening the lid
