Outdoor Ducted Cable

Toyota1968

I am about to finish my big garden project and have a few questions about outdoor cable requirements.
I have installed 4 inch duct across the long runs (under lawn etc) and want to know what sort of cable I can use in these ducts for lighting / cctv powering etc - do I need armoured cable in the duct ? - i would not assume that the duct will be 100% waterproof.

For other areas I will have to fit cable to a wall or bury at the foot of the wall - again what type of cable should i be asking for ? swa or nym etc etc

Are there any additional complications to be considered when using multicore (say 4/5 core) compared to std 3 core.

The maximum cable runs should by 65 metres but will typically not be longer than 25 metre.

finally - when running cable over outside walls for typical security / pir lights what should i be making sure is specified ?

Many thanks

you should be consulting with the contractors before the ducting is laid and when ordering cables

problems can easily arise with the ducting and cables otherwise

-swa anyhow in the duct and down low

-you might be able to use to some nym-j off the ground
