no i got some questions wrong not just one or two
Is it Michael?What is the name of the line that separates a circle in to two equal halves?
No - it's B.I suppose technically it's D, but in reality it's going to be B.
Then WTF did you answer D?It really was a question I got last month in the exam so I answered D ... I knew they wanted B.
No - BS 7671, in Table 54.8, tells us that for these supply neutral sizes you use a minimum of those main bonding conductor sizes, but that the local distributor's network conditions may require a larger conductor.YES it is a question about BS 7671 and BS7671 tells us the answer is B unless the DNO overrule it then you must follow the DNO, therefore following the DNO is explicit in BS 7671 so the answer can only be D
Yes you can because Table 54.8 tells you that the DNO may have overriding requirements and therefore to size your main bonding cable "in accordance with" 54.8 (the wording in the question, please note) you'll be selecting it in accordance with the fact that the DNO might have their own requirements and that therefore unless you know they don't you should contact them.B is wrong because you can't just size the PEB conductor from table 54.8, unless you know for certain that the DNO has no overriding requirements, which you couldn't know with out consulting them.

dingbat is absolutely right - just read what is in front of you.
But this is not the first time, even today, and nor will it be the last, that I've encountered a truly mind-boggling inability to simply read what's written.
And those 50% of tutors who got it wrong?
They can't read either. There's nothing wrong with the question - the source of their confusion and the cause of their failure is their poor reading ability.
Wrong!The diameter of a circle separates the circle into two parts of equal area.
Any line intersecting an arc (including a circle) in two places is a "Chord".
The chord of that particular question would have a length equal to the diameter of that circle (between its intersecting points)
But the question they asked was the "Name" of the line not the "length" of it.
