In short, yes. It is a test board, so there is actually fed from a board and RCD. I think the 2 cable, low test is a patent of Megger. Which prevents boards from tripping.

Why did you use 2 Lo and not 2 hi, was this because you have an upstream RCD?

So im not sure why your testing pfc on the L-L L-N on the tester it should be L-PE for L to E pfc then for PSC should be L-L L-N setting both tests are 2 hi......

Where did you input the earth lead in the back of the tester for the test? also do you double this value if its 3 phase?

The Green earth lead goes in the green L2 port on the back of a Megger Multifunction tester. Other testers will he different. You do not double the value for 3 phase. The earth fault current will only travel down one of the phase cables in 3 phase, to activate the protective device. Therefore even in 3 phase, the calculated Ipf will always be 230/Zs
