Discuss Tri-rated vs singles in the Electrical Forum area at ElectriciansForums.net
Is it OK to use tri-rated cable in conduit rather than singles (6491X)? Obviously of correct rating. If so, why would anyone buy singles as the tri-rated is cheaper and seems nicer to use (I have not used it before until very recently, hence the question).
Cheers
But you can get 1mm in tri-rated.I've just checked prices online for 100m of 1.5mm
You can use bare ferrules (without the plastic funnel bit) which gets around that problem - but to say it's a PITA getting the strands into them would be an understatement ?Other possible issues with smaller sizes of tri rate are that it's not so easy to get multiple conductors into a terminal when they've got ferrules on
I rarely use them, more for lights/appliances where you are terminating in to small screw terminals.I use bare ferrules a lot, used a load today! But I'm not sure I'd use 1.0mm singles in an installation. Isn't there a regulation saying 1.5mm minimum?
That is a good point, same as for the 6243B sort of T&E that can run hot, think it through!one thing to remember, the cable ratings are for conductor temp of up to 90 degrees.
you may need to go up a cable size if you are running close to max capacity.
assuming you are using devices and terminals that are rated for 70 degrees.

I have used a lot of the thinner tri-rated from 0.5mm to 1.5mm but in control panel style of situation and they generally don't have the same thermal issues.Yes you can get 1mm tri rated, but how often is that going to be of any use in a conduit/trunking install?
In conduit or trunking?Thanks for all the replies. Good point about the ferrules, but I have loads in stock for terminating flex.
Davesparks - TLC have Tri-rated cheaper than singles:
1.5mm² Black 6491X - £17.60 / 100m
1.5mm² Tri Rated Cable - Black - BS6231 - £15.23 / 100m
TBH I don't use singles much either, but based on this I think tri-rated is the way to go for the infrequent times I do (usually a single run to an outside light).
Cheers guys.

Can you get trirated Conductors inside an swa?
I think bigspark17 was asking about the finer stranded = easier to bend conductors.No, tri-rated cable is single insulated flexible conductors.
Thats like asking if you can get unarmoured SWA.
