Question: 1 / 400

What additional consideration is needed for the cubic inch count when installing a receptacle?

Yoke size

Grounding requirement

Both yoke and ground

When installing a receptacle, the cubic inch count must take into account both the size of the yoke and the grounding requirements.

The yoke, which is a mounting bracket for the receptacle, occupies space within the electrical box. Depending on the type and size of the yoke, it can affect the overall volume and thus the cubic inch count that is available for conductors and devices.

Additionally, grounding requirements necessitate the consideration of the space taken up by grounding conductors. These conductors need to be included in the calculation as they will occupy volume within the box, influencing safety and compliance with the National Electrical Code (NEC).

Hence, accounting for both the yoke size and grounding requirements ensures that the installation not only fits within the electrical box but also meets safety regulations, preventing overcrowding that can lead to overheating or failure.
