SERIES R TRUNKING CAPACITIES AND DIMENSIONS
SINGLE-CORE PVC-INSULATED
CABLES IN TRUNKING
For each cable it is intended to
use, obtain the appropriate factor from Table A.
Add all the cable factors so
obtained and compare with the factors for trunking given.
The size of trunking which will
satisfactorily accommodate the cables is that size having a factor equal to or
exceeding the sum of the cable factors.
The number of cables installed
should be such that the resulting space factor does not exceed 45%.

SERIES R TECHNICAL INFORMATION
The base is supplied with pre-cut
elongated holes at 250mm centres along its length. Fasten the base with No. 8
round head screws and washers. Avoid over tightening to permit thermal movement.
All base joints should have a 3mm gap (min) to allow for expansion left between
consecutive lengths which are covered by the coupler. Fabricated
internal/external bends are installed as per the base. The internal segregator
and dividing fillet both clip within the base.
ACCESSORY BOXES
These are clipped to the D rail
and secured by means of the accessory mounting screws for the 1 gang box or the
independent fixing screws on the 2 gang box. This offers very secure location of
the boxes.
