Bungalow ceiling wiring

Should the electric wiring in the roof void be laid underneath, or on top of, 150mm thick Stay Cool insulation?

Convention would put it underneath in conduit.

Many thanks.

USA, romex, no conduit necessary. On top or under is fine. Walls or ceilings the same as long as its not an exposed or habitated space. But its got to be secured with staple clips & stuff. 

 

I think for OP, it would be easier on top, especially if the insulation is installed already. 

 

Just another pov.

But, TIT.  Conduit because rats and other critters like to eat through stuff.  On the bottom so it doesn't interfere with radiant heat reflection.

Yep TIT. 

 

Id still use conduit, but screwed around the perimeter, and run across the top to the service points. Easier & stuff.

Personally, I don't bother with conduit for lighting circuits but I think it is required by the Thai "Electric Code".
