I finally got round to upgrading my wireing regs to 17th edition amendment 1 this week, I passed by a long way but I got 1 question that for the life of me I couldn't find the answer to. Now it's torturing me wanting to know the answer, like that song stuck in your head you just can't put a name too.
The question:
A thermally protected ballast on a flamable surface should be witch of the following:
A) class A
B) Class I
C) class p
D) class II
I went class II but that was just an educated guess, could any one enlighten me?
