24v ran with 230v cable

Nathan Rose

Hello

I have got to run some 24v dc robus 2 core wire to feed led strip along the roof of a barn. The only route available has already got some lighting switch wires and a smoke detector supply running the length of the barn. I am wondering if running the 24v wire parallel to the 230v wire will have any consequences? The longest run will be 9m, and the robus cable is rated at 300v. 

any advice is most appreciated. 

thanks

    Could try and put the cable in some flexiable conduit to give a better barrier but this will also alter its reference method and heat decipartion for the cable calc wich is a mute point as 24V on a 300v cable.  May be worth considering label the conduit along it length to highlight it is a DC cable inside.

    no need - a conduit will not help EMC unless it is metal and earthed at both ends. By all means label the cable if you wish to, but the regs do not require you to do that. Just clip it up - it will certainly be safe, and will almost certainly be fine EMC wise as well, just dont cable tie the DC cable to the mains one...
