Hi, yeah there's questions about different types of protective devices and there opertaing characteristics i.e bi-metallic strip for overload, and the magnetic component of an R.C.D trip coil.
On load switching, and off load swithing/isolating.
Locations containing different zones.
You need to be able to calculate ZS, PFC, PSCC.
Also theres a little about the adiabatic equation, you wont need to use the formula but understand it's use and where to find the relevent information in the regs book regarding it's application.
I don't think its completely closed book, i thought you could use your regs book and on-site-guide?
