Separate spur AND additionally clean separate earth!

Posted by: Ulrich Hohn on 06 July 2002

Mark Packer gave to 27 June an important advice in the thread "Dedicated Spur Question". Over dedicated spur was said already much, so that some does not look in. One cannot judge unfortunately always from the heading contents. Therefore I want to repeat it here:

"Get your electrician to create a clean earth for the Hi-Fi distribution board which goes back via 10mm2 earth wire all the way to it's own earth-spike buried in the garden. (Don't connect the hi-fi to the general house earthing.)
This really makes a *big* difference to the sound quality."

I was already before via 10mm2 earth wire to the general house earthing connected. Thus had I mean doubts whether it brings me somewhat.
Not the less I obeyed its advice yesterday. The result is great. I hear now during the day as well as before at 23 o'clock!

regards,

Ulrich

Ulrich,

Danke.

I discovered this after having installed a separate spur with it's own independent earth. I didn't connect up the earth at first. The spur was an improvement but not all that I'd hoped for. One afternoon I connected up the independent earth spike too. BIG GRIN.

The spur makes a difference but, for me, the independent earth *really* made BIG difference.

So, Ulrich here's the next useful bit of the advice:

Keep the earth spike well watered so that it provides a constant, high quality earth for the system.

[Plant some flowers around it if you're embarrassed about your neighbours seeing you ;-) ]

regards,

Mark

I haven't gone as far as adding a separate ground rod for my system. However, changing the pipe clamp for my main house ground from a very corroded steel one to a shine new copper one made a big difference. It wasn't quite as good as the dedicated spur, but almost.

Ok Mark, So you connected a separate spur, presumably with earth going back to the house distribution box.

Did you then replace the Earth with the new independant one, or Add the new one as well as the original.

If I understand the regulations correctly. In the UK you cannot replace the earth, but you could add an additional on as long as the original goes back to the distribution box.

It's an independent earth for the mains spur alone.

Well, it was. The house is being rebuilt(!) so that spur is now defunct.

But, it all check out ok when I had the wiring certified.
