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 designed to be IP44 rated when the lid is
closed, allowing the floor to be washed.
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 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 1.65mm. This is well within the maximum
allowable deflection of 3.0mm.
Note:
This test data specifically refers to the 265 x 265mm 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.
