Overcurrent devices shall not be located which of the following places?

• A. Near easily ignitible materials, such as in clothes closets
• B. Where exposed to physical damage
• C. In bathrooms of dwelling units
• D. In attics

Answer: (A)

The main point is that overcurrent protection devices must be placed in locations that minimize fire risk and remain readily accessible for safe operation. Putting them near easily ignitable materials, such as clothing stored in a closet, creates a real fire hazard: in the event of an overload, fault, or arc, heat or sparks could reach fabrics and ignite them. Fabrics and lint are combustible, and a confined closet amplifies the danger, so the code prevents locating the device there. Other spots like bathrooms, attics, or places exposed to physical damage have their own concerns (moisture, heat, accessibility, or damage risk), but the critical safety concern this rule addresses is avoiding proximity to easily ignitable materials.
