The wood needs to be treated with fire retardant.

Why?

Terminals and unsheathed cores have to be in noncombustible
enclosures,
but *sheathed* cables are routinely run through wood joists, behind
panelling etc.


But this would not be classed as panelling or structural members, it
will be (in effect) a form of trunking and AIUI electrical trunking
needs to be non-combustible.

Are you saying that electrical enclosures don't now need to be
non-combustible ?
