thanks chris, you explained it well. i am an electrical contractor and aslo an electrical inspector. an electrician asks me about the above procedure. now i can tell him that it will be accepted, and is code compliance.so now i can tell the Mississipi guys about a new trick of the trade.
A single hammer blast on a hollow wall about 8" above or below the box allows the NM cable to be fed inside the block and inserted into the box. No excess chipping above or below the box to insert the NM cable required.
Two questions, Has anyone talked to a mason about "blowing out that many blocks????
second; I know about the 1 1/4inch rule or a 16gauge nailing strip. But is there anything on the thickness of the wall cavity????
I always ran my runs verticaly into the ceilings and puchased a 2inch piece of 16gauge steel and ran it up th furring strip all the way to the cieling.
