Morning all,

Situation: New consumer unit + meter inside old metal box which used to
house wired fuse CU. The metal door has been lost many, many owners in the
past.

CU - House = various twin-earth and some 4mm^2 (in trunking)
Meter - CU = "double insulated" 25mm^2
Supply - Meter = singular insulated 16mm^2.

According to the rules the last bit doesn't quite follow the rules
(even though it seems to be the most recent bit of wiring).

Given the lack of metal door, is the best solution to stick the supplies
together into fat plastic trunking? Or is there some other way to make
them safe?

Gerd.
