I need to run 10mm SWA to building at the end of the garden, the electrician suggests clipping it direct to the fence concrete post which are solid enough and says is permissable as digging a trench is not an option. I am concerned about the UV issue, the support element as the posts are 6ft apart.

I have asked him could it be run in galvanised conduit as this would solve the UV and support problem but he says that he has never done this and is a waste of time.

Could I ask you guys for your opininion on this.
Thanks
 
I've got one its just the issue of can it be run in conduit or is this overkill. The sparks just wants to clip the SWA to the fence post.
well he's wrong then. BS 7671 recommends a spacing of cable fixings and it's far less than 6 ft...... for 10mm SWA, I'd be spacing the cleats at somewhere about 18"or less.
 
Assuming the cable is 3 core the horizontal fixings should not exceed 400mm apart. Find another electrician.
Yes its 3 core, I was hoping running conduit between post which are solid and concreted into the ground would solve the problem of 400 mm spacing of horizontal fixing, in conduit the cable would be supported along its entire length.
 
Running SWA in conduit would be bizarre.
Yes but certainly would increase proterction against damage to the outer PVC. What I'm trying to get at is there a problem in running it in conduit. I understand now that clipping to the fence is allowed and should be clipped every 400mm horizontally.
Wot about running a catenary wire just above the ground, fixed to the concrete posts, and attaching the swa to that? :)
Not considered that, length is 22 metres. I was thinking of running just above the concrete baseboard on the fence.
