Can an octagon fixture box that was also found to be a junction box, be closed and covered over in the ceiling after remodeling. Box not needed. There's a huge difference between covering it (with a plate), and covering OVER it (with anything that makes it inaccessible). Is It Against NEC To Cover Junction Boxes? No. As long as the cover meets certain requirements, it’s fine to cover a junction box. The NEC requires that junction box covers be accessible, which means you should be able to remove them without damaging the building structure or finishes.
Except for underground box covers that weigh over 45.4 kg (100 lb), doors and covers of enclosures used solely as pull boxes, splice boxes, or junction boxes shall be locked, bolted, or screwed on. Question 2: Is this a violation of the §1926.405(b)(3)(ii) requirement that "boxes shall be closed by covers securely fastened in place?" Answer: Paragraph (b)(3) of §1926.405 applies only to pull and junction boxes installed on systems of more than 600 volts. But, in all cases the junction boxes are not covered and are not fastened to anything. They were just left lying on the insulation. Here's a couple of pictures of what I found:
Your best bet is to either remove the box all together or just put a cover plate on it. Your other option is to run a new circuit to the new box and de-energize the circuit to the old box and mark the source wires as "NOT IN USE" at your panel in which case I believe you could cover it over.Boxes shall be closed by covers securely fastened in place. Underground box covers that weigh over 100 pounds (43.6 kg) meet this requirement. Covers for boxes shall be permanently marked "HIGH VOLTAGE." The marking shall be on the outside of the box cover and shall be readily visible and legible.Exception: Listed boxes and handhole enclosures shall be permitted where covered by gravel, light aggregate, or noncohesive granulated soil if their location is effectively identified and accessible for excavation.
Some of the electricians on our project are under the impression that any unused openings in their junction boxes are considered effectively sealed/closed by the installation of the external fire pads and do not require an actual KO seal prior to the installation of the fire pad. The one plastic box with a metal cover is safer because it has a cover, but then takes another safety and code hit because that cover is not grounded. As far as code requiring a cover for the boxes pictured - see 314.25.
