Flexible ducting laying on wires

[ACEsterhuizen]

Sorry to butt in but a few pointers which you could maybe check whether this type of wiring in fact still complies with all regulations. (besides all the other test eg insulation resistance etc etc) (or maybe get an installation electrician to do it for you)

I have to second Andy and recommend a complete rewire it's much cheaper than the loss of life and/or property.


6.4.5 Open wiring

NOTE Open wiring consists of single-core insulated conductors that operate at not
more than 250 V to earth; however, this is not a recommended installation method
for new installations. Amdt 5

6.4.5.1 Open wiring shall not be installed:

a) under thatched or wood-shingle roofs,
b) in parts of a roof space where the working height is less than 750 mm,
c) in roof spaces that are intended to be used (or are used) for storage,
unless the wiring is suitably protected against mechanically damage,
Amdt 5
d) within 1 m of a trap door unless the wiring is suitably protected
against mechanical damage, or Amdt 5
e) where it will be in contact with flammable material.


6.4.5.2 Each conductor of an open wiring system shall be visible where it
is installed on, over, or next to beams that can be used for walking on, or
it shall be suitably protected against mechanical damage. Amdt 5

6.4.5.3 Conductors shall
a) be fixed at intervals not exceeding 1,5 m to building elements such as
walls, rafters or purlins, Amdt 5
b) if there is no ceiling, be at least 3 m above floor level,
c) Deleted by amendment No. 5.
d) Deleted by amendment No. 5.
e) Deleted by amendment No. 5.
f) be supported within 600 mm of the point where they enter conduit or
other building elements, and Amdt 5
g) be fixed in such a way that the fixing method does not impair the
conductor insulation. Amdt 5
6.4.5.4 Where conductors enter a conduit, the conductors shall not be
strained. Metal conduit shall project enough to allow a bush and an earth
clip to be fitted. Amdt 1; amdt 5
6.4.5.5 Where the current-carrying capacity of conductors is impaired by
thermal insulating material, the appropriate correction factors shall be
applied.

the bold is where i will look first judging by your pic.
