Description
Cu conductors, PVC insulation (numbered cores), Laid up, Black PVC sheath. 450/750 V
Industrial and commercial applications
Used as a connections type of cable between control cabinets where a number of control signals are required; or for use in any areas where control of equipment is required.
Both unarmoured and armoured controls are used in a similar style of application, the only difference being that in the case of unarmoured cable the customer may require mechanical protection of the cable.

MULTI CIRCUIT OPERATION

The circuit ratings given below are single circuit ratings, i.e. they relate to a single set of 2 or 3 loaded conductors. 
Whilst these cables are not intended for use as power cables, if they are to be operated with more than one set of
conductors loaded for significant periods, the ratings given above should be reduced by application of an
appropriate rating factor from the following table:
