Basically..house fire Dec 22,2009. I have to rewire complete home to make it equivalent to a new home in nec2008 code. This is a Victorian home with pine plank walls and oak plank floors and ceilings. Am I allowed to run cable through walls without stapling? If I need to staple, how can I do that with solid oak walls?I can access wiring from above and below each floor but not within walls.
