Earth rings on SWA cables

[Plonker 3]

That can be a major problem though, how often do you gland a SWA off but give the instructions to the final user? Or for most other items thinking about it. I know things like fans, light fittings you should but certain things just get thrown away once finished with.

i was always under the impression that banjos were for the express purpose of fitting fly leads, e.g. when using non metallic enclosures. with metal enclosures and no requirement fo fly leads, then the banjo serves no useful purpose.

I seem to remember that BICC made a SWA gland that had serrated edge. It did NOT ship with a earth ring. That was many years ago, I would code it a C3 myself.

Still need a banjo or Piranha earthing nut with fly lead, if connecting a SWA or similar to a metal enclosure with bolted gland plates Tel.

i agree..:yes:

ECA inspector would pull it as a non conformity, the one thing you have to meticulous about is the bonding, SWA cables with an integral earth have to have the sheath bonded and I am sure that the carcase of the DB would not be good enough for an inspector.

WHY NOT??

It always has been in the past, though i must admit i've always used serrated lock nuts when fixing to metallic enclosures...

Would it not be better practice to use bolted rings and earthing lugs and take a fly lead off the bolted ring and terminate along with the circuit CPC? Guarantees continuity of the armouring as you also have a secure gland to the fixture or accessory.

Piranha serrated lock-nuts combine both facilities, a biting surface and fly-lead terminal...

Ah handy!

Exactly what i use much better neater and quicker
