Farm Outbuilding Office & TT Earthing etc.

The wild geese are migrating now. We can see them overhead flying south as they appear out of the morning mists, calling to each other as they fly in large numbers in a large V formation. Then they disappear back into the high level mists. Some say that they will fly to S. Africa.

Meanwhile, a local smallholder who keeps four footed animals, has built a new wooden building to be used as an office and farm storage unit. The new proposed office is only about 25 metres square.

He asked me about installing a few sockets and lighting in the new building.

Presently the nearest supply is a plastic cased TT earthed consumer unit.

Near to the new build there are two earth electrodes used solely by the electric fencer unit. These are run in parallel. How far away from any TT L.V. installation earth electrode should they be?

Will the electric fencer interfere in any way with I.T. equipment?

Shall I supply the office with P.M.E. earthing, or shall I TT it?

I have my own thoughts on these matters, but wish not to have missed any safety issues.

There is a miniature Shetland pony that can't eat regular grass. It is allergic to it. Its hay has to be “sterilised” in a hay steamer rated at just under 3kW.

Thanks,

 

Z.

  • I have to agree with you on that last, Z, exporting PME for an office outbuilding is fine if no animals present. I have done just that on my farm (which, BTW, is supplied from a pole transformer but is PME). Exporting PME requires a 10mm earth (or sufficient CSA on the SWA).
