7.3.6 Cable Installation to Controller
Wiring runs should be made neatly and routed to allow enough spare cables for
possible changes/additions at a later date.
Spare cores are to be bundled and routed to a convenient position clear of the
mains. The ends are to be insulated to make the loom secured. Spare cores of ELV
cables are to be loomed separately to the cores of LV cables. Note: normally spare
cores are earthed at the controller end, as this makes Periodic Inspection Insulation
Resistance testing much easier.
If cable idents are required then these are fitted to cores before termination.
All cables into the controller should be fed into the outer case as close to their
termination positions as possible. This is to prevent unnecessary damage being
caused should any cables need to be moved once they are in place. Care must be
taken not to obstruct the Electricity Supply Company cut out with any cabling.
7.3.7 Refitting CET bars
Re-fit the CET bars in the most suitable positions to suit the cable run.
