Low resistance

" It should have: Low electrical resistance to earth"

TT earths don't normally have low resistance, and there is no reason they need to NT 00:42, 29 May 2008 (BST)

"low" being relative - under 200 ohms being low in this case.

The later section "Testing the electrode resistance" covers the detail. I think as a bullet list of desirables "low" is ok. Perhaps "adequately low" would be better here? --John Rumm 00:54, 29 May 2008 (BST)

I guess if TT can just as well be described as 'low' and 'not low', then there's little point using the term low (without any clarification of what it means) in this situation. TT earth Rs are high compared to some things, low compared to some. As earths go they're the highest R of them all. NT 00:29, 30 May 2008 (BST)
