Hello All.
I am taking my 2396 written exam in December this year, therefore i am knee deep in practice papers.
In case anyone else is in the same boat, i wanted to post some questions, to see the difference in answers, (If any at all) if those of us more knowledgeable would like to have a go. Please try to quote regs numbers for your findings.
1) Explain in detail, the requirements of BS7671 with regard to protective earthing within an installation, using the protective measure of ADS.
2) State three examples of sources for SELV circuits.
3) Explain the circumstances that would require the use of an IT earthing system without ADS.
4) Explain the considerations that must be taken into account when using the risk assessment method of determining the requirements for surge protection with regard to overvoltage's of atmospheric conditions.
Have fun.
