swa run outside to feed consumer unit

[daz1963]

Hi all. Maybe a dumb question to some of you but have never done it before, can,t find a reg that says not. I need to find a way up to the third floor of a property thats being converted to flats to feed that flats consumer unit from a 6oa switch fuse on the ground floor. Was originaly going to go with 16mm t&e and serperate earth inside the building in trunking but the run is really not straight forward. so was thinking armoured in cable tray run up the outside. can anyone see any problems with this that i need to think about. as in no rcd protection to this cable so is armour enough?

no reason why not, except that tray will look the pits on domestic. could you not use some 1 1/2" waste pipe in best colour to blend in, run the SWA in that?

With suitable warning labels to show 240v, in case a plumber (surely not) cuts thro it thinking it's a waste pipe.

Thinking,,,, there won't be adequate support for the SWA on waste pipe.
Just use SWA cleats.

It's fuse protected, no different to any other external run cable.

i'd be more inclined to fix a " cut here " label. LOL.

Kind,, but cruel??

yes use swa why not just cleat to wall nice and neat

I would try to ensure its not on show to the scum bags if its external.

Cleating this cable is probably going to be the better method. The only problem i can see, is how are you going cleat this cable above the second floor level?? Not on a ladder i hope?? ...lol!!

Roped access, simple!

long ladder.

SWA cleated and trayed (if more then one cable). Done it up the side of council blocks and it looks reasonable.

Thanks Guys. some good points. Oh and ladders are not my strong point. but there is a scaffold there at the moment.

Don't forget to de-rate the cable if its run in poo pipe, reference method B?

why would you run it in pipe.....just clipped direct should be ok....keep it straight..it will look ok....

And why spend extra budget on tray for no good reason? By the time you've fixed the traywork it'd be half the time to have cleated it direct. Just remember your long level on that day!
