Full rcbo boards????

[D00DY_T00DY]

Hi all,

Probably going to seem like a novice question just wondering what techniques you lot have for full rcbo boards to keep it neat.

Put 5 in today for a temporary supply for ground workers on a genny; earth rod with a Zs of 2.13ohms (fairly good?)

Anyway it was a complete nightmare trying to keep it neat with the earth and neutral flexes out of them.

I've only installed less than 10 just wondering all your techniques for rcbos?

I kept all the length on these and tried to coil them nicely behind the cpc and neutral terminals.

Someone is bound to be along at any moment to point out you're defining fine wire incorrectly Ian but I agree with you.

 

[Pete999]

how many 13A plugs are there which form part of the fixed wiring and therefore come under the remit of bs7671?

Beat me to it Dave

I won't loose any sleep if they do Dave

Yes 1mm can be crushed quite easily, and there is an improvement to be made there too. I'm not aware of any simple fix for this other than paying a bit more attention to the correct tightening of the terminal screw.

Describing situations where this problem occurs but it cannot be fixed by ferrules doesn't in any way support the idea that ferrules are unnecessary, it just looks like pointless mud slinging.

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.

Does anyone have any links to their fav ferrule crimping tool?

Hi Pat - I got one of these, it works fine but in truth I've not used it enough to really say.

I've got same kit as Wilko, no complaints. Box it comes with large enough to put crimping tool and crimps too

For the sake of a couple of quid for a big bag of ferrules I can't see any argument against it.

Someone who builds panels will be working to a standard which requires their use.

I thought that post was a pee take

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.

Nope didn't know boot lace ferrules had a crimper

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.

I bloody like that very neat.

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

 

[onions1066]

Dave I respect your views and can see you have alot of knowledge but I very much doubt you can even work to the standards you preach. Regulations are worded in such a way which leaves the overall decision with the installer and I have to agree with spin London on this one.

 

[Bobster]

Just throwing it in.

Not only is the reason to treat the terminations of fine stranded conductors to save damage.

The main reason is the copper creeping. Admittedly not going to be an issue with small bits like an RCBO tail, but on higher loads it's going to rear its head.

 

[D00DY_T00DY]

Annnnnywhoo...
Rather than arguing about the big holy book of regulations.
I attempted another rcbo board(21 way ) with a different technique; connecting the rcbos then my circuits. Got some little cable ties ready to tackle this monster. Still no luck. After the 5th rcbo things got unruly.

Next attempt shall be a circuit at a time, then an rcbo. Either right to left or left to right.
Determined to get a spot on rcbo board. Practice practice practice

Do you have to use the particular brand of board your are using?

I don't pick the boards, whatever our wholesalers have. Currently BG

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.
