"Dried In"

[laketime]

We use the term all the time that a house must be dried in before we can start roughing in with romex. Is there an actual code section that this practice is derived from or is it just industry standard.

I would only assume it could be that the wiring/devices were not rated for wet/damp locations or UV resistant. With no walls/roof, the wiring would be subject to the elements.

Not sure that you can find that anywhere. Just that the AHJ may make you remove all the wiring if he see water in the structure and your wire is in there.

PS did you know that vinyl siding directly over OSB violates the building code so you still might not be "dried in". LOL

R703.1 General.

Exterior walls shall provide the building with a weather-resistant exterior wall envelope. The exterior wall envelope shall include flashing as described in Section R703.8. The exterior wall envelope shall be designed and constructed in such a manner as to prevent the accumulation of water within the wall assembly by providing a water-resistive barrier behind the exterior veneer as required by Section R703.2.

See if this is what you are looking for: From NEC 100

Location, Dry. A location not normally subject to damp-
ness or wetness. A location classified as dry may be tempo
rarily subject to dampness or wetness, as in the case of a
building under construction.
