You can have multi core tri-rated cables.
I don't think so, tri rated cable is single core flexible cable to BS6231, UL and CSA standards

You can have multi core tri-rated cables.
You’ll have to excuse me if I use the incorrect terminology. I’m basically an apprentice and have been set this as a task to find out. So it’s 4 core flexi I think they call it. Big thick black cable with no amouring, just 4 cores It’s runs under the floor and then up and onto ladder
It's obviously a H07RN multicore.Well I don’t know. I’ve pulled in a multi core this week and it was called tri-rated by all the sparks. I will picture it tomorrow
Don’t understand why there’s any debate?Now that we know its not actually tri rated cable yes, ladder or tray seems more likely.
There's an interesting debate to be had on whether it is ever allowed, for SWA or anything else.
It's called tri-flexNever heard of tri-rated flexible cable. There are rubber cables available in that size and if it is a long run someone has made a serious error.
It's called tri-flex
It's also mechanically strong.
I one time drove a genie MEWP over a live 50mm 5 core flex.
If the cable is installed in some kind of metallic containment then use the containment as the cpc, size permitting of course.We’ve pulled in a 185 cable just and realised that we need a neutral. It has 4 cores, brown, black, grey and earth. Can we use the earth as a neutral if we shrink wrap it with neutral sleeve and then run an earth separate? It’s a tri-rated cable, so no armoured to use as earth.
