Hi,

Just saw another thread where a new lad has posted a pic of his board he is wiring...

It got me thinking...

When you change a CU or fit a new one on a new build or where ever etc..., how do you go about connecting everything in the board? Looking at the other thread he has taken the breakers etc out and neatly positioned the neutrals and CPC etc.

I normally fill the board up with breakers then struggle to get it all in neatly.

What do you do? It would interesting to hear.
 
If its populated I take all the MCB's / RCBO's out AND often also take the bus bar out so that when I'm threading all the cables in it can be done as neatly as possible - that includes the tails, main earth and bonding!
 
I like to keep all conductors the same length if possible (L.N+E), usually 1.5 times the height of the board , and leave the slack behind the din rail , that way if you need to alter or reconfigure the internals you have not left conductors too short, or if ever the board is changed in the future ,,

Me 2 but on most CU changes I find myself extending the conductors!

the MCBs, RCDs/RCBOs and the incomer should all come out as a module....dont forget that the din-rail will unscrew (2 screws 1 each end)....just drop the lot out...there....you now have all the room you need to turn them tails and bank all them finals in nicely....
 
Thats where Ive been going wrong, I usually just pull all the wires through together then spends hrs working out what goes where! If there are any left over at the end I just push them down behind everything ......

mate your just making work for yourself there just get them stripped and fill the spaces until you've done every circuit or you've filled all the spaces and if there's out left over push them down the back like you have been doing. Why go to all the bother of working things out that's over rated
 
See I was always told third time lucky but I suppose I might be able to get it right the second time if I was having a really good day



but on a serious note I always mount the carcass then put all the earths away nice and neat then the neutrals then put the dinrail and breakers in and do the tails and the lives..........simples

I would hazard a guess your electrician may be able to contact your DNO and have the switch swapped to a MFS very quickly..
