HAs it been specified what exactly is a non combustable consumer unit, I have been out of the loop for a wee while and the last scuttlebuck was metal consumer units all round,

I think metal will comply.

What a load of bollox, they need to worry about training people properly first before worrying about the kit installed, I have a wylex DB in my house which is at least 25 years old and still going strong, the training is the issue these days, guys using the wrong screwdrivers and balls of wool left in DBs where they have had no or little training in installing one.

Balls of wool?

I have seen some new boards with 20" of slack left on every core, for some reason the DIs these days are taught to leave a lot of slack in new boards, it looks like there is aa ball of wool inside some of them, no wonder it overheats in there lol

From memory they did teach to leave ridiculous amounts of slack.
The argument was that if taught to leave silly amounts from the beginning there would be some left once all the practical training had been forgotten.

My memory from real training was to leave enough to reterminate @ any other terminal in the board / JB.

Yes Spin but are they insisting on tinwear as compulsary,

Yes very true mate, I was taught to leave a small amount but enough to reterminate, not 2 foot though haha

You’ll be OK with a pre cast concrete CU.

We have bird's nests around our way.

To be fair at times i have left a ball of cable in several 4 way cu's, due to the nature of our production processes our consume units are often relocated a foot this way or that way so out of laziness we would leave a lot of slack on circuits for retermination at a later date

Another bodge we have hit upon is the steel cu having a straight piece of conduit straight up into a angle besa box and then several metres of slack in flexible conduit before it enters the busbar trunking.

I have noticed in the last couple of years the amount of flexible pipe being used is incredible, the wiring methods seem to be changing lol, and probably not for the better either.

to be honest the trunking isnt rammed even with slack from over 100 cables in there.

this is controls though not power, i wouldnt leave anywhere near that much slack on power cables
