High today at a fault call i noticed that on a row of lights that were out the swa that fed them was also feeding the other row so two seperate circuits fed via 2 seperate mcbs eg lives, neutrals+ cpcs all in the same multicore armoured i informed the client this would need rewiring with a new feed for the other row. However was just looking to see if anyone knew what regulation would back up my claim? Cheers
 
2 rows of lights with one feed? Whats the problem? it's not 2 different circuits it's 2 sets of lights on one circuit
 
Thats what i was askinng is it acceptable for two circuits in 1 multicore cable then never heard of at college or seen in the last decade on site and to trevor this was definately two circuits not two rows on 1 feed
 
2 rows of lights with 2 seperate feeds = 2 circuits. It matters not that they are fed from the same multicore, 1 live to each row 1 neutral to each row 1 cpc to each row. As wirepuller said whats the difference between that and a bit of trunking with 2 circuits in it?
I've read the op properly now hehe
 
Oh cheers mate i was a bit worried when i saw it i know in pricipal its the same as numerous circuits in a trunking/conduit system just never seen two circuits down one cable and was a bit worried if it was ok just in case someone isolated 1 circuit and thought they had killed the entire cable.
 
Six cores in this cable l,n+cpc for both circuits no shared neutral that would defo be incorrect
 
"I've been having a bit of a think about that cable and I think we'll be OK because.........."

If you think about it, we use multicore cables for multiple circuits all the time - what else is YY? My background in theatre lighting is almost totally reliant on a long established practice of running six separate lighting or power circuits (L,N,E) down 1 x 18 core 1.5mm cable (Socapex).
