Outer Sheath Cable Colour

R J

Is there any guidance, best practice or standard when selecting cables dependant on the use of the circuit? As for example a Red cable will usually indicate a Fire system cicuit, a Yellow cable would indicate a 110v CTE construction supply.

I'm aware of the Table 2 in the IEC 60309 relating to plug and socket colours, but I'm sure I've seen some guidance in the past relating to cables also.

    Blue seems to have become established for mains voltage emergency lighting, for example from a generator. Possibly a network rail requirement, that has spread to non railway premises.

    First seen at Waterloo station and now at many larger stations.

    Yellow is the norm for 110 volt flexible cords, but not seen yellow outer sheaths for fixed 110 volt cables.

    I have seen orange PVC singles in conduit for fixed 110 volt circuits.
