Hello
I'm just reading through a few examples of fault report sheets in preparation for my next practical week.
Fault: Office water heater does not work.
R1 + R2: 0.35 ohms
Rn + R2: >99.9 ohms
I'm fine with getting R1 + R2. Disconnect the line conductor and shove it into the earth bar, but Rn + R2? I'm confuzzled! I've been racking my brain and leafing through my notes and I just cant remember how!
Can anyone help with this conundrum?
Thanks,
Gary
