Does anyone know of where I can find info on BICC, aluminium conductor wire armoured cable of the type used in the UK for electrical fixed wiring installations in the late 1970's, early 80's ?
(When aluminium was used in place of copper, I believe due to the high costs of copper at the time )
I need to be able to work out the CSA of a multicore cable simply by measuring it's overall external diameter.
I don't have access to the seperate cores as I can't power down the system.
I have a 'lookup' table for copper conductor armoured cable, & need a similar table for aluminium.
I did discuss the issue with a UK cable supplier - they wouldn't give me any info in case they got it wrong !.
TIA,
