Having read these questions it tells me that its not yet time for me to attempt the 2391

I'm looking forward to the suggestions being posted, because having my nose currently in the NICEIC Inspection, testing and certificate book very limited information seems to stand out.

Do you have Guidance notes 3? If so page 30.
If not, first three in the conduit list are;

Securely fixed box lids and protected against mechanical damage.
Inspection fittings accessible.
Number of cables to allow easy draw of cables not exceeded.

ii)
Go to checklist in the BRB 522.8 P.101
522.8.6
522.8.1 but also OSG App 5 P.117

b. You have not described the install but it would probably need an RCD regular test label OSG P.39, label given advice on Periodic Inspection, maybe if an existing install a warning of two BS 7671 version cable colours. Most are in OSG P.37

c. GN3 P. 92.
Presence of Earthing conductor.
Presence of CPC
Presence of protective bonding conductors

Hope this helps, coffee break over.
