It is commonly used for fixed wiring in domestic and commercial premises, but it is not intended to be used where it is subject to regular movement or sunlight, because the sheathing is affected by ultraviolet radiation. Green and yellow sleeving, which is sold separately, is required to be used to cover the exposed ends. There is an overall sheath of grey PVC BS , or white for low smoke compound BS , although prior to white over sheathing was also available in PVC so care should be taken with older cables of unknown age.
In the Republic of Ireland the situation is different. From , Irish wiring rules require a CPC with a cross-section equal to that of the main conductors and insulated in green and yellow inside the full length of the cable, from the new standard IS Versions of flat cable are also available in smaller conductor sizes containing three current-carrying conductors in addition to the circuit protective earth conductor. These configurations are commonly used for applications such as switched light circuits, battery-backed emergency lighting which requires a switched and unswitched supply, extractor fans with a run-on timer which require a switched and unswitched supply, mains-powered interlinked smoke alarms, and central heating thermostats.
Before the advent of PVC, this tubing was varnished cambric. These are required because it is not permitted in Australia and New Zealand for the Neutral conductor in a "Twin and Earth" cable to be "re-purposed" as a "Switched Line" conductor, as is permitted the UK and in North America.
TPS cables greater than 2. The CPC conductor is always stranded.
