Site fabricated wooden trunking/capping

I'd say it was concealed on a wall, not concealed in a wall - so 522.6.202 etc don't apply. So yes, in effect, it's decorative timber trunking. In essence no difference to those PVC trunking systems that pretend to be cornice or dado or skirting boards.

I'm not sure it is classified as trunking, or any other kind of recognised cable containment, because it doesn't comply with the relevant standards.


It's basically building/construction materials, and the cables are concealed behind them.


So, I think I'd agree the cables are not concealed in a wall or ceiling, and I don't think it's difficult to deduce where the cables are.


At the end of the day, it's far better than the cable being stuffed inside the wall with whatever insulation is there ...



But what strikes me as a relevant discussion point, is .... What is the Installation Method [in Table 4D5]?


OK, even if we choose Method 103, it's still not a massive problem for a 32 A RFC in 2.5 sq mm, ref Table 7.1(i), p65 of OSG, but suppose someone is reading this in the future, planning something similar for another application ... and I apologise in advance if no-one else is intrigued by the question.
