I think its a amazing system but seen as I have not made one off in 7 or 8 years think its not as common in normal situations anymore.
Obviously still has its uses but none I am ever likely to be involved with (Petrol stations etc)
It's probably just too costly vs other wiring methods these days.
some of the old guys I worked with worked at dounreay nuclear station for a while.
they would slag of my apprentice attempts at terminating mi and regale me with stories of 19 core imperial mi cables
with 2metre tails for panels etc.
try putting the seal on that sonny!
