2382-622 exam question

[IvayloP]

Hi there. I am a student part time for level 1 &2 in UK. I will have an exam 2382-622 but I stuck to one of the questions. Actually when I looked for information around and make some thinking about it I think the answer would be,B - Maximum demand, because everything else can be directly measured or calculated. Am I right with that though.
I don’t know why the picture can’t be attached. The answers are
A- nominal voltage
B- maximum demand
C- prospective fault current
D- earth fault loop impedance

B - has nothing to do with supply characteristics.
The answer you are looking for is on page 510 of BS7671.

Look at 313.1

Because of 313.1 I am stuck on that. They said- shall be determined by calculation, measurement, enquiry or inspection.
Nominal voltage, PSCC , earth fault loop impedance, maximum demand e t c.
And then “the above information should be provided by distributors on request “
So everything from above can be measured or gets from the energy company. But the question is which of these can be ONLY determined from enquiry- and the once that isn’t there is PFC . But it can be achieved when earth fault loop impedance is done with the multimeter or by calculating.

Yes but in EIC all of the four answers are under the supply characteristics, but which of these can only be obtained by enquiry?

Do you have BS7671 because the answers is on page 510. B does not fall under supply characteristics, it may be one of the answers but it is not a characteristic.
If you don't have BS7671 then I will post a pic of the page.

Yes I have it. The page 510 is EIC certificate. Yes all four answers are under supply characteristics. But the question is which of these can ONLY be obtained by enquiry. Not by measurement or calculation ,only by enquiry the grid company.
By my latest opinion from the answers here I think the nominal voltage Only can be obtained by enquiry.
