2392 Practical Exam question

[PGS]

Help

I am taking an exam on Thursday 11th at 2.00pm for C&G 2392 (practical).

My problem is testing of PFC/PSCC and PEFC.

PFC/PSCC is testing between incoming L - N with the installation isolated - no problem.

PEFC is testing on incoming live and earth, but is it the incoming earth or the earth bar with all bonding connectors in place?

Also, for polarity testing on incoming supply, using the same earth as for the PEFC test?

Thanks

PGS

You are correct . earthing conductor disconnected when doing obtaining Ze . Leave earthing conductor connected when measuring PFC
