What must be agreed before the extent and limitations of a periodic inspection are set?
How should the extent of sampling be selected for a periodic inspection?
Sampling
Component fitted to limit transient overvoltages from lightning or switching, which BS 7671 now expects unless the owner declares the risk of damage tolerable.

What makes a sampling plan defensible during periodic inspection?
Before commencing a periodic inspection, what should the inspector agree and record with the person ordering the work?

Outcome 2 - Safety Management
What is the minimum acceptable insulation resistance value for a 230 V circuit tested at 500 V DC under BS 7671?
Abbreviated name for the cable core or armour that carries earth fault current back toward the main earthing terminal; steel-wire armour can serve as one if its area is adequate.
