Open boxes are considered a safety issue and are commonly noted during a professional home inspection because they can pose a fire or shock risk. That's a junction box, and its job is simple but important — it houses wire connections safely. Sometimes, though, these boxes are left uncovered. While it may not look like a big deal, an open junction box is a safety hazard and a fire risk. Safety concerns arise. The right box should be safe, serviceable, and easier to approve on site. NEC junction box code mainly comes from Article 314, with related rules from Articles 300 and 250. Both the Occupational Safety and Health Administration (OSHA) and the National Fire Protection Association (NFPA) require the insulation and protection of wiring energized at 50 volts or higher if the wiring is equal. It is considered a fire hazard to have open junction boxes.
