What worries me about the use of self-drilling screws as that they shed swarf (as shown in the picture provided).

I would be terrified that some of this could end up in locations where it could cause a breaker to fail to operate in an emergency.
i see your point, but drilling holes for nuts and bolts also sheds swarf. if in an existing , working DB, this coulsd cause the same problem. different if drilling is done (and cleaned out) before MCBs etc.are installed.

Agreed.... up to a point.

Swarf is an issue wherever / whenever it is created, but it is much easier to manage if drilling the holes in the traditional manner where the inevitable creation of swarf is uppermost in one's mind.

Self-drilling screws, IMV, create swarf "silently" in the sense that the person driving the screws is often blissfully unaware of the swarf.

I agree with you , but that just looks dog rough.
Altered that lol , I need my eyes tested.
 
I couldn't help myself I would have to blind those sharp ends, even if I had to make it rougher with a bit of sleeving lol. :)
 
it's OK though, it's a proteus DB. can't make it any worse.

Has anyone else noticed that it’s The most likely board type to contain shoddy workmanship by the installer and non matched breakers?
Or have I just been unlucky?
 
There cheaper than other DBs so it is generally the shoddy people who just throw them on the wall and get a quick buck.
The guy who put this one in couldn't even be arse to cleat the main Inc or put a bolt through the Inc supply banjo, but he did do a separate earth at least. SWA gland earthing 20190723_104149 - EletriciansForums.net
 
I thought those self-drilling thingies were for attaching wiggly-tin, profiled steel cladding, whatever. Anyway, i don't like the sharp, pointy bits inside that box...still, if it speeds things up?
Can you install them with an impact driver? That would make it faster! Then you could use the same impact driver to tighten the terminals too, saving even more time...
 
Once again we see evidence of the industrial/commercial side of the trade quickly following the downward trend of the domestic, eh, rus? :rolleyes:

Years ago, the guy asking you to quote for work in his factory knew what he wanted.
often knew how he wanted it doing.
nearly always knew roughly what it would cost.
also, often appreciated that your quote was better than the other 2, NOT because of price but because he had talked with you. understood your way of working and trusted you.

now days

he or she will pass the task on to the purchasing department who's only mission is to save the company money.
they have no understanding about how long things last or why this is the better way of doing it than that.
they will happily give the job to any person who comes in with the lowest quote.
there argument is always that it is all to the same standard otherwise it wouldn't be allowed or certified.
it always costs them in the long term but that is of no importance to them.

small companies are the only place bucking the trend in my area.
