Do the regulations tell you that where PME conditions apply the main bonding conductor should be determined after consultation with the supply undertaking AND NOTHING ELSE?
Yes or no?
No. But they do require consultation with the supply undertaking, which is what the answer in option D says, so answer D is not incorrect.
Multiple choice exams like that do not have more than one correct answer to each question. That's not how they work, and you really ought to know that.
Yes, such exams should not have more than one correct answer to each question. That's the whole point of the original query, because this one clearly does have more than one correct answer.
You have.Who's rejected it as wrong?
It is a multiple choice question, with 3 wrong answers and one right one. That's how they work.
That is how they should work if the instructions for the exam state that one, and only one, option must be selected as the correct answer.
And that's just why this question and its answers are poor, because there are not three wrong answers out of the four given.
By selecting D as the right answer you are automatically rejecting A. B and C as incorrect. That's how it works.
That's how it should work if of the four answers provided one is clearly correct and the others are clearly wrong. But that's not the case with this example.
That's not possible because the multiple choice question does not work like that.
So of the four options provided, one should be correct and three should be incorrect. Not two correct answers from which you have to deduce which answer is expected.
Do the regulations tell you that where PME conditions apply the main bonding conductor should be determined after consultation with the supply undertaking AND NOTHING ELSE?Doesn't alter the fact that answer D is still correct.
No. But answer D doesn't say that the conductor size should be determined after consulting the supply underaking, AND NOTHING ELSE. If it did, then answer D would clearly be incorrect.
I don't want to argue that at all.But BS7671 does require such consultation. You've just said so - It's in the note with table 54.8. Unless you still want to try and argue that just because BS7671 does not use those two precise words that they somehow don't count.
Read the problem through four times, with each of the possible options in turn.
Where PME conditions apply the main bonding conductor should be - Half the c.s.a of the earth conductor to Table 54.8
True or false?
Where PME conditions apply the main bonding conductor should be - Selected in accordance with the supply neutral to Table 54.8
True or false?
Where PME conditions apply the main bonding conductor should be - Determined after consultation with the consumer
True or false?
Where PME conditions apply the main bonding conductor should be - Determined after consultation with the supply undertaking.
True or false?
