Specifically designed to house switches or receptacles, these must be sized correctly to avoid "box fill" issues, which can lead to overheating.
The primary function of the enclosures discussed in Article 314 is to house electrical connections and protect them from the environment. By providing a controlled space for wire splicing and device mounting, these boxes prevent accidental contact with live wires and contain any sparks that might occur due to short circuits. This regulatory framework ensures that every box—whether metal or non-metallic—is durable enough to withstand the physical demands of its location.
These are used primarily in underground installations where access is needed for pulling or splicing cables.
