R2 test without removing cover

[tomodo]

Hi all when performing an r2 test prior to commencing an EFLI test would it be acceptable if the board was made from metal of course to test from the point to the outside of the board rather than to the earth bar? Just for when you are working with large 3phase boards full of cables.

The cpc should be disconnected within the distribution board.

In guidance note 3 it shows it being connected to the MET with a crocidile clip

In my opinion that is incorrect as the cpc could be broken but parallel paths may not suggest this. From previous threads you clearly have issues working within the distribution board and as such how will you prove polarity as this is a dead test which should be carried out before the circuit is made live.
