The minimum internal depth required for outlet boxes that do not enclose devices is how many inches?

The minimum internal depth required for outlet boxes that do not enclose devices is indeed 1/2 inch. This depth is specified to ensure that the wiring and connections can be safely housed within the box without risking damage to the conductors or compromising electrical safety. Maintaining this minimum depth allows for proper installation and minimizes the risk of overheating or short circuits, providing an essential standard for electrical installations.

Boxes that do not enclose devices must still provide enough space to accommodate the wiring and any necessary connections, ensuring that they meet code requirements for safety. Inadequate depth could lead to cluttering of wires, potential electrical hazards, or difficulties during installation. Proper adherence to these standards is crucial for both compliance with the National Electrical Code (NEC) as well as overall safety in electrical work.
