SY Cable containment

GHEC

I know the subject of SY cables in fixed power installations pops up a lot but please bear with me.

I know that SY cable does not meet any British or harmonised standards and is 'discouraged' under BS 7671, but can be installed and noted as a departure on the installation certificate. 

As it will need to be 'safe' under BS 7671, should SY cable be installed in metallic containment such as steel trunking?

    I really cannot understand why SY or YY cables are not acceptable to BS7671. We used to use miles of the stuff in heavy industry. It's odd that the Bodies are only too quick to 'harmonise' with foreign standards, even the dreaded and suspect AFDDs from the USA, yet SY & YY seem to be orphans who have been left out in the cold.

    Arctic cable is quite often left out in the cold ;)
