SY Cable containment

SY will be used by every electrical installation apprentice in the land when they do their AM2. They also have to complete an EIC where the cable is already marked up as a departure. 
Miles of the stuff used in industry here but I think many employing it believe the braid is definitely for robust mechanical protection and, as GK says, it is often connected to an industrial plug for that very reason!

Direct personal experience over many years taught me that SY is more abrasion and crush resistant than any other flex I know of.

I lost count of the number of times a 440V extension in SY was run over by a heavily loaded forklift truck, yet continued to function. W e used to use rubber flex with a braided inner, then another inner sheath but it always seem to get cut up more easily by machine shop turnings embedded into the solid tyres of the truck. SY seemed to stand it much better. And no, the FLT driver refused to be educated.

Oh dear ... but is it the FLT driver's issue or the H&S duty holder's? I think the legislation would say the latter in this instance, inadequate risk assessment and controls (SY cable was not really the "correct" answer here, if there actually ever was one).

No one was really too concerned, other than for production to restart as quickly as possible! The leads were 3 phase 110V which fed what we used to call ''man fans', basically semi-portable floor standing fans which were used to keep the machine operators cool. If a fan packed up, they sat down until it was repaired - usually FLT damage to either the fan itself, or more often than not a severed trailing lead. No RCD, just Crabtree C50 type C 3 pole mcbs.
