Yes in my #112 gut feeling which was literally me considering the centre point being a parallel fed device which would be the same as a single cable of ¼ length of the whole ring.
True, maybe from now on we will have to say what's the Zs at the doner socket?
In previous timesI've put in many temporary supplies, think public entertainment, field day contests etc etc, and sometimes I've had some 'rather long runs' in service. One of my most common tests for VD is to make a COT
Sorry John my bad, not 8Bm but 1/8 as a %age , still dont follow it though and yes some people do insist that the 2m rule does apply from the point or JB on the ring to the spur itself .
Well, we theoretically ought to ask but, as you've pointed out, very few people will be able to measure. I suppose that if they had an EICR or EIC which included the circuit in question, they could get a ('probably still roughly the same') figure from that?
Quite, and that hardly requires any 'working out'! - as you say ¼ of the entire length of the ring, which is the same as what I said (using the language of the OSG), namely ½ of the the distance to the midpoint of the ring. Certainly very far removed from 'one eighth'!
Who said the access needs to be "easy"?
Good question....errr me?
OK. To phrase it differently, which Regulation states that access must be "easy"?
Oh sorry I just use common sense.
Otherwise known as opinion. But we should stick to the facts.
Well yes my opinion is that a jb should be easy enough to get to.
It's certainly my preference also, but it isn't what is required by BS 7671.
I try to go above and beyond.
