The notes
Exactly as they are on the site.
Continuity of protective conductors, including main and supplementary bonding, can be tested two ways. Do them in either order; in the assessment both count as the first test in the sequence.
Test method 1 needs a line conductor: you link line and CPC at the board and test across them at each point. Bonding has no line conductor. So for the bonding there is only one method: test method 2.
