More Code catastrophes uncovered in these faulty installations...
I Need My Space
The panelboard shown in this photo originally had the required workspace; however, over time, the space was taken away by the installation of the plumbing pipes and expansion tank. Unfortunately, this is an all-too-common problem, because other tradespeople don’t know the electrical code requirements. 110.26 requires access and working space to be provided and maintained about all electrical equipment to permit ready and safe operation and maintenance of such equipment. Obviously, this space has been compromised. 110.26(A)(1) requires a minimum of 3 ft of clear working space depth in the direction of live parts. 110.26(A)(2) requires a minimum of 30 in. of width or the width of the equipment (whichever is greater) in front of the electrical equipment. 110.26(A)(3) requires the work space in front of this panel to be clear from the floor to a height of at least 6½ ft or to the height of the equipment (whichever is greater). This work space is so a worker can have some room to work safely on the energized equipment. Even if this equipment was de-energized, it would still be virtually impossible to work on it in a safe manner.
Standing Tall, But Not Proud
This junction box must be supported in accordance with one or more of the provisions in 314.23(A) through (H). In accordance with 314.23(E), an enclosure not exceeding 100 in.3 that contains only splicing devices, does not support a luminaire(s), lampholder, or other equipment, and is supported by entering raceways, shall have threaded entries or have hubs identified for the purpose. In addition, the box shall be supported by two or more conduits threaded wrench-tight into the enclosure or hubs. Each conduit shall be secured within 3 ft of the enclosure or within 18 in. of the enclosure if all conduit entries are on the same side. The exception in 314.23(E) permits a conduit body to be supported by intermediate metal conduit, rigid metal conduit, rigid polyvinyl chloride conduit, reinforced thermosetting resin conduit, or electrical metallic tubing. Since the 4-in.-square box is not a conduit body, the exception is not applicable in this application. EMT and FMC are simply not permitted as a supporting means for junction boxes.
