Where do you get the 8% voltage drop for three phase figure from? I'm stuggling to find that one
I too just sat the exam, question no 19 (the one after the 100mA RCD question) is the one that threw me with the short circuit capacity of an circuit breaker. I had no idea of the difference between Icn at 6KA and Ics at 10KA and the question being what would happen if a fault current (PSCC I believe) of 8 KA were to exist? I asked a good few others after and likewise no one seen to know. Overall I did think it easy (ish) for a 2391er but only the hard results will tell. All the best to you fellas.
I did the exam today too. As said compared to past papers I've done it seemed a lot easier! Shame there was no fault path diagram as that would have been 15 marks in the bag for the VD questions I did 6.9 for lights and 11.5 for both power questions. 100mA RCD is only did 1/2 times and 1 times.
6 weeks to wait now fellas :-O
