Hello everybody, I'm new to this forum and require some help.
I'm an apprentice electrician studying in my 3rd year of college and have currently just passed my test and inspection exams. However I am struggling on 1 thing. Don't get me wrong, I know how to test and carry out all procedures correctly, but need help knowing where to look to verify my readings. I have the BS7671 17th Amendment book and the OSG, but where exactly am I looking to verify;
r1
r2
rn
(R1+R2) / R2
I know where to find Max Zs & RCD Trip times, and insulation resistance is simple enough. But I'm just a little rocky on finding the above max readings.
Any help would be appreciated.
