I think I may have found a couple of errors in the key but would love to confirm that's its not my understanding that's incorrect.
There are also a couple of questions I don't know how to answer and was hoping anyone could help me out.
Perceived errors:
Section C
Question 1
For cooktop and under bench oven they seem to use full connected load and I believe it should be 50% connected load.
Question 4 C (Final Sub-circuit)
Question states 2.5mm v90
For the mV/A.m rating they use the V90 rating instead of using the V75
(table and column indicate 75 but answer and method uses 90)
I need help with the method of the following:
Section C
Question 7
Finding the conductor size and the table isn't a problem but can anyone please tell me the calculation for the max circuit length?
Question 8
I found the Commercial KA Rating and the clause but am unsure what calculation they've used to come out at the 0.0092ohms
Thanks very much.
