Recessed Wiring Box
The Recessed Wiring Box is used to provide a recessed container for
a standard MK ceiling rose base model 1161WHI in which to make the
electrical connections required for a ceiling lamp. The Perforated
Flange Ring is fitted to the Circular Recessed Wiring Box to provide a
key for the plaster and must be assembled before the Circular Recessed
Wiring Box is fixed in place.
Pendant Cable Connector
This provides the interface between the pendant cable and the MK ceiling
rose base. It centres the pendant cable and provides the support for
the cover ring by means of two N42 neodymium magnets housed in the
underside. This part attaches to the MK ceiling rose base by location
in the two rectangular cut-outs adjacent to the cable knock out area
(described as the ‘Batten Lamp holder Mounting’ on Figure 1 of the MK
leaflet 44957PL Ed. 2).
Circular Cover Plate
The circular cover plate is primed on both sides and ready to receive a
paint finish to the external face only.
Earth Leads
These are provided for connection between the earth terminals on the
Recessed Wiring Box and the Circular Cover Plate to the earth terminal
on the MK ceiling rose base.
Installation Instructions
Insert the Recessed Wiring Box through the Perforated Flange Ring.
Install an appropriately sized timber noggin between the joists in the
lamp position. The face of the underside of the noggin is to be 38mm
from the room face of the plasterboard. A simple way of positioning
the noggin is to drill an 86mm hole in an off-cut of the plasterboard
that is sufficiently sized to span the joists (if two or more layers
of plasterboard are being used add accordingly). The Recessed Wiring
Box can be inserted into the hole, the plasterboard offered up to the
underside of the joists and the noggin can be positioned vertically and
fixed in position.
connect to the earth terminal on the MK ceiling rose base as illustrated
in Figure 8. Please note that the male spade terminal on the Circular
Cover Plate is thicker than the terminal on the inside of the Circular
Recessed Wiring Box and therefore, the two earth leads must not be
interchanged.
Colour codes used for earth cable in the UK are as follows:
GREEN/ YELLOW = LOAD terminal marked
Prepare the pendant cable by carefully stripping back the outer sheath
of the supply cable to expose 135mm of the inner brown conductor and
125mm of the inner blue conductor. Then carefully strip back the inner
cable to expose 10mm of wire. If using an existing cable with soldered
ends, they should be trimmed back and re-stripped to expose new clean
conductor. On no account should soldered ends enter the terminals.
Thread the pendant cable through the central hole on the Circular Cover
Plate.
Wrap the pendant cable conductors around the Pendant Cable Connector as
illustrated in Figure 5 noting the orientation of the blue and brown
conductors. Ensure that the outermost cable sheathing is sufficiently
pushed up into the recess on the Pendant Cable Connector so that the
blue and brown conductors are not visible when the cover plate is in
place.
The Pendant Cable Connector is seated in the rectangular cut-outs
on the MK ceiling rose base as illustrated in Figure 7. It must be
installed by inserting one of the legs into the first cut-out and then by
gently squeezing both legs to allow insertion of the second leg. Once
installed, the remaining length of cable to the pendant lamp should be
wrapped around the cord grips on the MK ceiling rose base and wired
into the terminals in accordance with the manufacturer’s instructions.
Slide the Circular Cover Plate up the flex and locate in the recess of
the Recessed Wiring Box so that it is supported by the magnets.
Before removing the Circular Cover Plate first TURN OFF THE MAINS SUPPLY.
Use the supplied magnet to remove the Circular Cover Plate as indicated
in Figure 10.
Once the ceiling has been plaster boarded, use a 86mm diameter hole
saw to form a hole in the plasterboard lining in the position that
corresponds with the timber noggin.
Drill a hole through the noggin for the circuit cables noting the
preferred orientation of the MK ceiling rose base is with the wiring
terminals beneath the earth spade on the Recessed Wiring Box. Note that
the knockout area in the MK ceiling rose base should be removed to
increase cable capacity.
Securely screw fix the Recessed Wiring Box to the timber noggin ensuring
that it is level and that the perforated flange ring is tight to the
underside of the plasterboard. Ensure that the heads of the fixing screws
are fully recessed into the countersinks so as to foul the MK ceiling
rose base.
The Recessed Wiring Box is plastered into the ceiling noting that care
should be taken to keep the inside of the Recessed Wiring Box free from
plaster and particular attention should be made to ensure that the rim
is kept clean. Following plastering, the area around the opening can be
sanded to ensure a true and flat finish between plaster and the rim of
the Recessed Wiring Box.
The lighting circuit wiring connections to the MK ceiling rose base
can be made before or after plastering and must be made in accordance
with the manufacture’s instructions on MK leaflet 44957PL Ed. 2. The MK
ceiling rose base is screw fixed to the timber noggin in accordance with
the manufacturer’s instructions.
Where passing through the knock out area in the MK ceiling rose base,
the circuit cabling needs to be squeezed so that the overall width is
narrow enough so as not to hinder the insertion of the Pendant Cable
Connector as indicated in Figure 4.
If there is sufficient slack in the circuit cables, the connections can
be made with the MK ceiling rose base hanging below the ceiling as
indicated in Figure 3 (ensure that the circuit cables in the ceiling
void are not clipped to the noggin in a way that prevents this). Once
wiring is completed, the rose can be inserted into the Circular Recessed
Wiring Box and fixed to the timber noggin. Note that the MK rose will need
to be tilted slightly so as not to clash with the earth spade mounted
on the inside of the Recessed Wiring Box.
When decorating the ceiling, great care must be taken to ensure that
the rim of the Circular Recessed Wiring Box into which the cover plate
is installed is kept clean from paint otherwise the cover plate will
not fit properly.
The Circular Cover Plate is decorated on the underside in the desired
colour. Great care must be taken to ensure that the paint build-up to
the outer edge is not too thick otherwise it will not properly fit into
the recess on the Recessed Wiring Box.
Cut the earth leads to length as necessary and carefully strip back the
outer sheath to expose 10mm of wire. Connect the spade terminals to the
corresponding earth spade terminals on the inside of the Recessed Wiring
Box (indicated as A1 on Figure 1) and the Circular Cover Plate and
