The NEC states that you cannot put metalic boxes onto masonry which may be
damp without a 1/4" airspace. Does this mean that you cannot use metal
boxes / emt on masonry basement walls? What about metal boxes /
masonry basement walls of a row home between the homes?
Thank you for your time and energy,
PS: This post was previously listed under NEC Clarification Needed which I
feel was a poor choice as it did not provide enough information. Since
there have not yet been any responses I am reposting it under a different,
much improved, heading.
