Hi all
In order to measure your pefc pscc, you need to test across all 3 line conductors then multiply by 2 record the highest value, this is correct isnt it.

The PSCC will be the highest in a three phase installation. Double the highest line to neutral value if your equipment cannot measure between phases.

Each line conductor separately the same method and connections as if you were doing it on single phase, take the highest of the 3 readings, and as you say double it. Job done.
 
Actually, I read that the reason for the x 2 is to allow for the remote possibility of a fault across all three phases, which is closer to 2x PFC of one phase to N or E, than 1.732 x
if I remember correctly it was Geoff Cronshaw on the IET forum. I may be mistaken, but I'm sure I'm not.
