If you're talking a plug fuse, the load is irrelevant. As it is to protect
the flex etc. In other words, a table light with a 20 watt bulb would be
fine with a 13 amp fuse if the cable was rated at 13 amps.
But that wasn't the question was it.
This was a mid-term test, so you would got this question wrong.
Often with examination question, the right answer is the one the
examiner is expecting. I have had that dilema many times.
I hand my grandson a sheet of A4 paper and ask him what shape it is,
he replies it's a rectangle. Wrong.
