We have an opportunity to wire a number of new site built/manufactured homes nationwide.The product is a 1.75" thick solid pine T&G stacked plank. The planks have holes drilled vertically every 1.5", which they use for structural purposes, as well as wiring and plumbing where applicable.In a WA state prototype, the inspector would not allow us to use the holes, as the wiring (even if in flex or conduit)was within 1.5" of the finished surface. Since the interior surface is the plank itself,obviously we could say nothing and ran wire on the outside of the planks, and on interior walls we had to stick frame cavities for traditional use. The manufacturer (New Zealand) was upset, because he called the holes "conduit" and are used all the time in their part of the world. Question: will this be an issue in most areas of the USA? I need to get a feel if this will be more trouble than it is worth. I could find no code to specifically address this unique application jmc@direcway.com
