You won't ....don't bother to look .I'm interested in this variable 'stability' that's being bandied around. Is it a measurable quantity? What's its unit of measurement?
Does the fact that I have in the last twelve months completed a TT installation using only a single rod....sorry 'twig' mean I'm going straight to hell?
Oddly enough, I cant find the reg or guideline that prohibits the use of single rods/branches/twigs
Its a bit like supplies to garden sheds ...at a school , hospital or industrial premises , a sub-main to an adjacent building would be quite simple, just run a cable of the appropriate size but when its a garden shed it becomes fraught with difficulties and has to be converted to TT , involving rods & twigs.
