I don't think it's such a silly question. Two or more cables side-by-side, touching, under capping would bring the grouping factors into play and reduce their current carrying capacity. So if you have two heavily loaded cables, I'd put them under separate capping.

A, On the basis this is probably a DIYer messing around I suspect complete answers would be a waste of time. If the OP is a learner they've not demostrated anything to me about posing a sensible answer themself for us to comment on!!

Are you saying that rating factors for grouping never apply when cables are run on a wall and capped?

A pointless exercise trying to do this, if you are wiring a lighting circuit for example in a house using 1.5mm2 conductors and behind the capping is a twin and 3 core to the switch as standard 2 way switching, then why would we ever consider grouping? why? alternatively, if we cap from behind the skirting board up to 450mm2 from FFL to a socket outlet and there are 2x 2.5mm2 6242Ys why would we consider grouping? why? if there is a 2.5mm2 and a 1.5mm2 cable behind Capping I would have to ask why these 2 differently sized cables were together in the first place????

your website states Electrician / Handyman I mean which is it, if you are the handyman can't you get the electrician with you to install the cables as per the requirements of the 17th edition ?

Since the OP hasn't said what these cable are for, you're just guessing.

Are you going to answer my question?

If you've forgotten, it was: "Are you saying that rating factors for grouping never apply when cables are run on a wall and capped?"

If you read the OP and what cables he mentioned you will see I answered the question, if you want me to answer your question which has nothing to do with the original one than I will be happy to do so.

Answer--- If 2 cables in a house are under One piece of capping would I bother to work out grouping factors. Um, no, I cannot think of any circumstance in a domestic circumstance where 2 cables under a 1" capping will need to be considered for grouping factors, It just isn't a requirement in this circumstance.

Guessing?? yes, after literally hundreds and thats being conservative of domestic rewires I cannot think of one situation where the ops post has any merit at all, not one if under a 1" capping.

Check the 17th edition regs book for installation methods and take it from there, you're part P aren't you?

A bit of advice, give it up now before you cannot see the top of the hole your digging.

Not taking sides but if groups of cables are clipped and capping applied then grouping factors should be considered!

Not with 2 cables Murdoch, ridiculous
