Hi you brainy people

Think am gonna have to dig myself a trench and put on my tin hat for this question but here goes, can a standard PVC/PVC cable be clipped direct outside to a wall or fence as long as its protected by rcd. Or does it have to have a form of mechanical protection.
 
it can, but not advised, as over time it will degrade with UV (if we ever see sun again).
 
How long is the run?,can it not go in conduit or be done in armoured,as tell said uv light will make the cable degrade over time,having said that seen many older installs just clipped direct,but for me it looks rough and those clips will be the first to rust and break leaving the cabl sagging.

and if the cable was clipped direct (method C)....would it require an RCD?.....and if so why?
 
My neighbour has t+e feeding a external light and I see it every time I do the washing up. His pvc has corroded and is in a bad way

Conduit would make a tidy job
 
I have some T+E going to my outside light, put in about 15 years ago and its fine. It probably helps that it has been painted several times since installation.
 
when i want to clip cables direct to outside wall without further containment i always use fp200 , its more durable and looks much neater when on show ;-)
 
any good solutions for clipping them to brick? got 20% success rate hammering them into walls, will prefer something wall-plug based :)
 
and who says FP200 is good for outside installation? if you use red FP200, it will soon go pink, FFS, and who wants that?
 
Well I ran a T&E up to my shed 20 mtrs away from my house 20 years ago clipped to a fence and it is still working and looks fine, I haven't tested it in 20 years though, apart from a pond supply, a weatherproof socket and 2 fluorescent lights it has not got much load on it, Biff is this okay?

i did.
and the cable manufacturers themselves.
and anything coloured red fades quickly in strong UV , doesnt mean its detrimental in any way.
and why would anyone use red cable surface clipped outside in an domestic setting ?
 
Because its surface and its less than 50mm, if it was more than 50mm from surface then it wouldn't require rcd @ glennspark

I'm in agreement with glennspark here. You seem to be under the impression that a cable outdoors requres RCD protection.

You will need RCD protection for socket outlets, but not for surface run cable (or SWA using any installation method).

Unless it's a TT supply.
