[QUOTE="Fleeting, post: 509686, member: 33702"] Yes I have just done the calculation and it is larger than the line even at 0.1sec for a considered instantaneous trip. I think you would have to quote the "rule of thumb" table in BS7671 whereby the line conductor up to and equal to 16.0 should have an equally sized cpc. I would also suggest 1.0 is undersized for a power circuit, see BS7671. I think you need to confer with your tutor but show them your workings. [/QUOTE]
