Just a bit of a muse at the moment, work won't happen for a while, though I do already have the ducting.
We have (what's left of - it was rotten, the storms just finished it off) a greenhouse which we're thinking of replacing with a garden room, man cave, workshop, whatever you want to call it - oh yes, SWMBO will be allowed half of it to sit and draw etc.
At the moment it's fed with a bit of SWA (only 1.5mm2 buried all of an inch or two down which is too small for my workshop. My plan is to dig a proper trench, put some ducts (and a drain) in so I can pull whatever cables I need later - network could be useful, definitely better power, but who knows - hence the ducts. Getting on for about 20m altogether.
So I'm thinking, why not drop a bare cable or tape in the bottom and add an earth electrode while I'm at it.
Downsides: Cost
Upsides: Supplementary earth electrode (TN-C-S supply), good hefty earth bonding (though technically not needed as no extraneous conductive parts), bigger/extra CPC which might make selection of cable*/protection combinations more "interesting" when I get to that stage.
Thoughts ? Good ? Bad ? Complete waste of money ? I'll have some of what you're smoking ? (only joking on that one)
And what would you use ?
* Does anyone make brown/blue concentric cable ? (not split-con)
