I've only worked on Proteus and some old MEM when it comes to three-phase stuff, can't say I've been impressed with either. Proteus not enough room in the sides (where the neutral/earth bars are) so you've got to stick your RCBO neutral in to the bar before you even clip the RCBO in.

It helps that learning curve D00DY and just think, you wouldn't have anything to moan about otherwise and oh how we enjoy that! Great that you are getting the practice in though, apprenticeship working!

Oh don't worry. I'd find something to moan about. Like the Tories being ahead at the moment.

And I'm on board duties(which I love)
 
i can see the regs 526.9 applying in say DBs etc but how does it apply to lamp holder attachments to ceiling roses. Surely the flex doesn't need ferrules as well?

made up pendants have ferrules on the flex.

business name idea.... Peninsular Electrical Services.
or..... Isthmus Installations.
 
We use the Curve boards from the local Denmans, cheap and cheerful, plenty of room to work etc. We used MK for a bit when the AM3 boards appeared but soon found they were useless. Faulty RCBOs, no terminals for bonding conductors, recalls and so on. If we do a CU change it will almost always be all RCBOs. All fine stranded conductors have ferrules fitted if we have to cut the factory fitted one off.

Part of remedial works after a T+I today included fitting ferrules to fine stranded conductors, it was shocking to see how few strands were connected on various RCBO tails, YY and SY flexes and tri rated singles that are used in a lot of the conduits. I must have fitted thousands of ferrules in the past few years. Makes a far superior connection IMO.

Yes of course it does.

The vast majority of factory fitted flexes will have ferrules fitted to them, or be ultrasonically welded into a solid mass.

Very nicely done board Freddo.

Thanks, I'm surprised no one has complained that the main earth conductor doesn't go through the tails gland with the l&n, I've never seen a good reason to, live conductors through the same hole yes. This was for a rewire of a property above a shop. TT earth, the DNO wouldn't provide a PME supply as they would have to disconnect the supply to the shop while changing the cutout, as their supply was looped through the flats cutout.
 
I don't see an issue with that either Freddo although I'll do it if practical. Typical DNO, never want to make that extra little bit of effort, often during the working day I'll see certain vehicles 'hiding away'. :)
 
I'm sure the shop would have coped without power for 30 minutes, it's in an old town and I think the cash register was an old manual model, no fancy card payments there. We chatted to the shop owner most days, she used to live in the property we were rewiring.

To be fair to Western Power, most of the workmen are good guys, the difficult part is persuading their office staff to send them out!
