Earthing of SWA

Ben22
Just trying to see people's opinions on the earthing of a SWA, usually I will. Use the generic banjo but I'm starting to think is this needed and have sometimes had to use a Bush and coupler to then connect my swa into a DB or accessory if space is tight, I'm yet to try the pyranaha nuts which I think will be better, 

Im just widnering if the banjo is really needed if a good solid connection can be made and verified

    I'd agree it's mostly tradition. If it was steel conduit rather than SWA but everything else the same, a banjo would be unheard of.


    With plastic enclosures banjos are a pretty poor solution anyway - as the plastic can deform over time under pressure so the conventional gland-banjo-enclosure-locknut arrangement isn't satisfactory - instead having the banjo on the inside between two locknuts is recommended. All in all the proprietary 'earthing nuts' are much better solution.
