What type of conduit for outdoors lighting?

[ElectronGlow]

I would like to fit a couple of LED floodlights along the house external wall and have been given to understand that the electrical cable needs to be run inside of a conduit of some sort. I would like to ask what sort of conduit I will require in order to meet current standards please?

Use plastic but be aware of it expanding and contracting according to temperature.
Or use Galvanised steel which may be overkill but will stay straight.
Most people clip the cable direct to mortar joints?

Or a nice bit of Pyro, ah those were the days.
OP only reminiscing, no one would fit a bit of Pyro now.

 

[Sharpend]

So just how did you go about fitting that on a damp day!! Pre make the loom inside then just fit to wall.

 

[roys]

Blow torch the dampness out before putting the pot on, or as you say make it of indoors if possible.

I would be happy to just clip it to the mortar joint with cable clips but I have been told that this would not meet regulations these days?

who ever told you that doesn’t understand the regulations we work too

Does anything rule out plastic trunking with clip on lid and sheathed T&E inside it?

Not sure how UV stable it is, got a feeling I have dealt with a bit a few years ago that was outside as it was shattered, when I was removing it it just disintegrated in my hands as it was so brittle.
Not sure if it was just a cheap bit bit of trunking or if it is a general thing with plastic trunking. I do know I have never used it outside because of that, I suppose it would also be a pain to get good neat joints into fittings.

I Just clip a length of R07 Hidden as well as possible if I have to run between fittings ,which is rare if no route inside to use .

If its good enough for trailing around flower beds it's good enough for me .

What is RO7?

What is RO7?

it's a outdoor rated rubber insulated cable you find it on many pre-wired outside garden lights ect R07 is just the abbreviation of its number

It's not that clipping cable to an exterior wall doesn't comply with current regulations. It's the type of cable that you use. Twin and skin does not like the sunshine and will become brittle over time and likely crack.

I'm assuming @sirsparkabit meant H07, but could be wrong. H07 is a type of flex, H07RN-F being the fully code for it.

You are going to struggle neatly clipping a flexible rubber cord I would personally use NYY-J.

 

[sirsparkabit]

I use p clips up under soffit ect but as you say the tuff stuff is good

I would. First used it in 1964 (imperial) and I loved it.

Impressive! Never heard of that before.

H07RNF... and many lights are pre wired in cheaper H05RRF...

I looked up what the difference is a few years ago, and it's just the voltage rating. 7 is 700V, 5 is 500V. Why you would need 700V on a bit of 1mm flex I have never worked out.
