Cables and trunking.

[john102956]

Hello. Could anyone tell me what would be the best size plastic trunking for 2.5mm square cable internally? my guess is probably 16mm square but not sure.
Thanks for your help.

16x25 should fit 2x T&E although check OSG for capacities

16x16 is big enough for 2.5 t&e, if it’s a straight run.... no bends.

25 x 16 gives a little more room.... 2 cables, again, if it’s a straight run.

Correct fixings required to prevent premature collapse in case of fire.

Never use T1 so T2 would be my choice

Hello. Thanks for that good answer. Could you tell what would be suitable size trunking when using 1.5mm flex cable? Thanks for your help.

In the past, I would try use 16x16 for one or even two 2.5mm2, and 2 or even 3 smaller cables. But often there would be tight spots like bends or trying to enter down the side of a pattress. So having used up what stock I had, I now generally use 25x16, saves time trying to get cables to fit properly. Unless there are more cables and something bigger is called for.

I think the wider trunking looks neater than the square section stuff.

4 x 2. get anything in there. including the gas and water pipes . even the kitchen sink with a bit of thought.
