So there must be hundreds of thousands of 13 amp plugs which don't comply then ?!
Regardless of which rules and regulations they fall under I'm talking about fine stranded flexible copper cable tightened with a screw terminal and without further 'treatment' , and with absolutely no ill effects.
I believe that regulation regards fine wire only.
It's upto the installer to be satisfied that the connection made is electrically sound and is suitable terminated.
If worried about crushing then use a torque screwdriver to manufacturers instructions
Yes there are a lot of fine stranded cables terminated in screw terminals with no ill effects, but there are also a lot which have failed as a result of it.
I find it hard to believe that you have never encountered a flexible conductor which has been damaged by the tightening of a screw terminal.
any plug fitted by a manufacturer or supplier of appliances will have ferrules used on the flex, all of the equipment which we get new with a fitted flex has ferrules on the end ready for connection.
The standards which apply to equipment building, panel building etc all require ferrules.
Should we all just stick our heads in the sand and resist simple changes which make things just a little bit better?
Beat me to it Davehow many 13A plugs are there which form part of the fixed wiring and therefore come under the remit of bs7671?
I won't loose any sleep if they do DaveSomeone is bound to be along at any moment to point out you're defining fine wire incorrectly Ian but I agree with you.
Hi Pat - I got one of these, it works fine but in truth I've not used it enough to really say.Does anyone have any links to their fav ferrule crimping tool?
I would suggest that the use of ferrules, depends on how frequently you would use them.
Someone who does the odd board with one or two RCBOs may not see the need, especially as compliance is easily achieved by the method I posted earlier.
Someone who builds lots of panels however may find the use of ferrules makes their work easier.
What makes me chuckle, is when people ask if your ferrule crimper is calibrated.

Sorry if it sounded that way, it was not intended. I got it for an rcbo job a while back and not needed it since.I thought that post was a pee take
Nope didn't know boot lace ferrules had a crimperSorry if it sounded that way, it was not intended.
I bloody like that very neat.Cut and ferrule for me every time.
Like to leave a little bit length still so the RCBO isn't completely useless if it does need to be moved a little in the future.

Very neat and tidy! Well done! Nice to see you taking pride in your work. You cant be that busy though )Cut and ferrule for me every time.

I don't pick the boards, whatever our wholesalers have. Currently BGDo you have to use the particular brand of board your are using?
proteus do a compact RCBO. 10A 1 Module SP 30mA Type B 6kA Compact RCBO | City Electrical Factors - http://www.cef.co.uk/catalogue/products/4126280-10a-1-module-sp-30ma-type-b-6ka-compact-rcboI'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.
I don't order materials. Still an apprentice bud hahaSurely you can ask them to get any board in you like. Just because CEF stock RPP doesn't mean I would use it.
Oh don't worry. I'd find something to moan about. Like the Tories being ahead at the moment.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!
And I was just beginning to like you but you're on weak and wobbly May's side(I joke. I'm not against democracy )Agree on the board duties not the other - yay!
made up pendants have ferrules on the flex.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?

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.

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.Very nicely done board Freddo.
I use this after much researchDoes anyone have any links to their fav ferrule crimping tool?
