Screed Depth – 25mm, 35mm and 45mm
Wiring Space
This graph enables the specifier / installer to determine which
depth the screed (plus floor covering) must be in order to achieve
a certain accessory wiring space and plug top clearance within the
floorbox. For example if the specifier requires a 35mm standard
wiring depth and a 45mm plug top clearance then the graph
shows that an 82mm screed (plus 8mm non-compressible floor
covering) depth is required. Alternatively, if the depth is fixed,
at 90mm for example, then by having a 45mm wiring space the
resulting plug top clearance will be 43mm. If additional plug top
clearance is required then the wiring depth can be reduced to
35mm or even 25mm providing a plug top clearance of 53mm
or 63mm respectively. Care must be taken to ensure there is
sufficient wiring depth and plug top clearance for each individual
installation. All these dimensions are based upon the floor
covering being 8mm thick when fully compressed. If the floor
covering is thicker or thinner then the screed depth must be
reduced or increased as appropriate. When no floor covering is to
be used the minimum screed depth with a 25mm wiring space is
64mm. For screed depths greater than 105mm, service boxes are
provided with fixed wiring spaces of 75mm, 100mm, 125mm and
150mm respectively.
