Onix Plus™ Floorboxes and Power Grommets
Metal Power grommet dimensions
The Metal Power Grommet is designed to be used in conjunction with the
Screed Base Unit, part number NXGB100-1 or NXGB100X-1, depending on
the depth of the screed.
Onix Grommets are are designed to be IP44 rated when the lid is closed,
allowing the floor to be washed.

Load Testing
Load Testing of Floorboxes to draft pr EN50085 Part 2-2 (Clauses 10.5.103
and 10.5.104).
The floorboxes have been tested to and comply with the loading requirements
of draft pr EN50085 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 fork trucks and heavier larger loads for example. 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 test wheel
loading classification achieved is 3kN and the maximum large plate loading
classification achieved is 10kN.
The Permanent Deflection graph shows the permanent deflection from
the test wheel loading at 3kN is 0.8mm and large plate loading at 10kN is
1.65
mm. This is well within the maximum allowable deflection of 3.0mm.
Note: This test data specifically refers to the 265x265mm sized cord outlet
box assembly. The other floorbox sizes also comply with the required test
criteria. Declarations of conformity are available on request for the entire
range.
