SWA to Garden Outbuilding

[Giuliano Besenzi]

Gents

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

Wot about running a catenary wire just above the ground, fixed to the concrete posts, and attaching the swa to that?

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.

bragging again?

Not considered that, length is 22 metres. I was thinking of running just above the concrete baseboard on the fence.

also bear in mind those posts have rebar in then and are prone to lumps breaking off when you blast at them with SDS.

I was jesting.

No, he's not ever been asked to run SWA in conduit abd says there is no need.

Well there isn't, so he is right.

I'd reconsider trenching. Not joking this time.

Even using 25mm conduit and I have not looked those fence posts are too wide apart for fixing distances.

Doable but I would end up digging up half the garden and there are too many other obstacles to overcome.

Wot about twin walled ducting laid at ground level, secure to each fence post?

Edit or rainwater pipe installed in a similar fashion (serious suggestion)?

When you are next in the high street look around you. You will see many examples of SWA being run in many situations which have probably been there years. It is designed for such an environment.

Not where peoples dig to plant their geraniums.

This is the first time the 25mm conduit has not been laughed at or dismissed, so I ask myself is it ok with the conduit if that too has additional support.

Not sure you will pull a three core 10.0mm swa through 25mm tube over 22m.
