National Electric Code, available for free
Yesterday while working at my brother-in-law’s house, a question arose about the covering for a junction box. Several of us were under the impression that you cannot cover a junction box with drywall, while others believed that this was perfectly legal and within code.
Curiosity got the better of me and I thought that I would probably be able to access the NEC online through my library. I may be able to do this, but I quickly found out that everything on NEC’s web site is available free of charge. There are stipulations such as the inability to print the documents, but it was refreshing to find this resource available for free in any form.
The answer to the previous question is, no you cannot cover a junction box with drywall. The code states that all wiring shall remain accessible without removing part of the building.
