Section 5 :
Cable Routing and Protection
Having established and marked the preferred route of the cables and decided upon the type of cabling
arrangement to be adopted, begin running the cables from the gauges furthest from the readout
location.
Where cables are not to be ducted, they should be strapped to the reinforcement, in a position where
they are least likely to be damaged, using strong tape or cable ties. Cable should be supported every
400-500mm and care should be taken to avoid over stretching the cables, especially where
movement/loading could take place when placing the cage.
The reinforcement bars can be used to protect the cables; for example by running the cables under the
bars to reduce the risk of damage where vibrating pokers are to be used.
Where significant movement could take place, the cable ties should be left a little slack and sufficient
cable left free and positioned so that it cannot be damaged.
Where cables are to exit from a concrete structural element, they should be protected by a short
length of plastic duct. This will reduce the risk of the cable shearing off where it emerges from the
concrete.
Once the cables have been fixed a full set of readings should be recorded for each instrument.
