Cable grouping within capping behind dot and dab

[Octopus]

Not with 2 cables Murdoch, ridiculous

I did say "considered" lol

HAHA, Fair enough, if it was a 3" capping with 4 or 5 cables under it and not a 1" with 2 as the OPs question I would totally agree.

Isn't grouping associated with number of circuits? So:

In the case of 2 x 2.5mm cables going to a socket outlet then how many circuits is that?

In the case of 1x1.5mm T&E cable and 1x1.5 3core cable then how many cicits is that (usually)?

nice little storm brewing here :-D

i'll wait a bit longer before jumping in lol.

Yes quite right, and when would 2 different circuits be under a 1" capping ?, unless the design was very bad never IMO.

Probably only when you have 2 way switching for upstairs in a multi gang switch downstairs, oherwise agree!

Oh god, I had better forget the 30 years experience I have and get the regs book out of the van.

...and get the regs book out of the van.

well if you did , you would notice that grouping factors can be ignored completely for circuits operating at no more than 30 % of their capacity.

what about all the circuits running down the wall to a CU ?
you'll need a 4 ft wide chase if you want seperate capping for each cable lol.

And what a useful intervention....

Grouping should be considered but 9 out of 10 CU's have grouped cables and do we go round derating them??????????????

Never had a 4ft wide capping area before biff, if that was needed due to a large home needing wiring I would work with the builder to design a better way, and move the board to a better location, still if your happy?

Anyhow whats this got to do with the OP question about 2 cables under a 1" capping?

Better go back round and snip those cable ties off the wires in that fuse board I tidied up...........

i sense a complete humour breakdown on the forum tonite so bugger the lot of ya with your dumb arguments on capping.
i'm off lol.

Awww I've yet to see you live up to your rep!

Oh no, sorry Biff, I was only kidding really :leaving: I will leave haha
