SWA banjo.

[Engineer54]

sorry I meant the effect of disimilar metals of the mild steel enclosure and gland, not earthing or steel armouring issues.
The way I see it it's not much different to the use of mild steel locknuts.

Can't really comment, as i can't say i have used galv locknuts on brass SWA glands. As far as i can comment, is that it all depends on how dry the connection between locknut and gland remains during service...

they also have teeth on the side that goes to the enclosure so they cut away paint for a good connection.

Having trouble this end at the moment to open the PDF link, i'll try again later...

I agree and think that enclosures in damp or wet environments should be of a stainless steel construction.

Now your talking ''Serious Money''!! lol!!

 

[Jonspark]

I'd be more concerned with drilling the holes for swa glands lol!!!

Now for a moan
Don't get me wrong but when I read about the skill required to gland Swa of whatever size,I like probably many others on here make comparison with cable glanding/jointing that we had to carry out and get assessed on as part of our practical exams many moons ago

The cable joints may have been lead sheathed with double wire armouring and take up to 2 hours or so to complete

How many I wonder (Tony excluded obviously) know about how to wind oil impregnated tape on to the cores and in the correct direction,strip the lead,the armourings would have to be cut to the correct length, cleaned with parrafin or the like,the assembly slow and deliberate

The everyday Swa gland is so very basic in comparison,a scour with an hacksaw.a trim with a stanley and nut a and bolt of whatever takes your fancy

Though making off a few of those cables it was a very long time ago, i'll admit i'd probably struggle a bit now. The worst cable i can remember terminating was the double wrapped steel tape cables. Bloody things used to rip your hands/fingers to bits in the process!! lol!!

 

[Guest125]

excuse my ignorance but why?

I think it is a preference thing. Seems odd to insist on a brass bolt when the locknut is steel, the distribution board casing is steel and the lug is steel.

read again im talking about pz2 head roofers

Definitely would not use them.

I hated those!

Loved PILC though, shame I don't get to deal with it anymore. The only time I would is jointing to a new length of XLPE.

He's gone

You forgot the Electrical Trainee option, don’t bother terminating the SWA.

Yeah, or a frigging BS951 clamp!

 

[sparkdog]

I always use brass nuts and bolts M6 or M8 usually.

 

[Tidy Max]

How come he has been banned again?

And just to be clear, are we saying using roofing nuts and bolts is a no no?
