SWA cables and banjos!

[ewatty]

Hi all, quick question on people's thoughts....

Someones installed a swa for a lift/ramp in a garage but not used any banjos either end.

its a 5 core cable (brown black gray g+y blue) it's glanded to a metal db on end, and a plastic isolator the other, now should it have banjos and fly leads both ends or just the plastic end or not at all as the sheath is connected via the gland at the metal db? Also as its 3-phase should it be phased marked as in brown marking on each live wire? Or just left brown black gray?

bit of a gray area in my head...

Any help? Cheers

Soz E54 it was just one of those things where in reality the regs don't consider every scenario and its practicably impossible to comply in such cases so rather than the IET draft in complex solutions they brush it under the carpet and hope it isnt noticed ..... only problem i have is the 2 responders to my query are well educated/experienced and realise its really not an issue but for the lesser knowledged and experienced its a good thinking point ....

I can see what you're saying and why Darkwood. Unfortunately there are quite a few other grey areas and contradictions within BS7671 and it's guides etc. I rarely follow BS 7671 to the very last letter, nor to any of the other internationally recognised standards named in our Contracts specification. But then i've been around long enough to know what i'm doing and why!! lol!!
