I got past the sceptical inertia when I read the Russ Andrews downloadable a few years back regarding clean power etc.

I did the seperate consumer unit bit last year and this year got as far as buying the copper earth spike. This seems a better idea than just sinking a wire into the ground as it probably gets to the moist soil easier during summer and makes for better contact.

As you can see, the costs of one of these won't break the project budget either.

I haven't figured out a) where to sink it outside, b) where to exit the house (through a window is not an option, but drilling a wall hole is OK), and c) which socket or ring to connect it to.

My bro-in-law did the same last year at his place and found a definite improvement in SQ. It may depend on how effective your native earthing is.

Now this is the sort of thing we'd end up discussing over a beer or three at the M customer club meeting, don't you think wink
