hi, i've just recently set up on my own and was wandering if anyone could help me filling out a test form for a rewire i have done for a friend,
1-What is the bs number for a bill 100a main fuse on a tns system?
2-How do i work out the prospective fault current?
3-What will the short circuit capacity be of the main fuse
4-where can i find the maximum permitted Zs for lighting circuit
5-where can i find the maximum permitted Zs for ring final circuit
6-where can i find the short circuit capacity for a lighting circuit
7-where can i find the short circuit capacity for a ring final circuit
8-Is R1 + R2 the resistance of live to earth on a low reading ohmeter
thanks to anyone who takes the time the help, i know i need to buy a copy of the regs, hopefully it'll be in my stocking
cheers jack
