A visual diagram shows a conduit body installed in a horizontal run of 3-inch EMT. The conduit body is marked with its volume in cubic inches. According to the NEC, when is this conduit body permitted to contain splices, taps, or devices?

• Only if it is listed and identified for the use.
• Never; conduit bodies are only for pulling and bending conductors.
• Only where it is marked with its volume and the volume is sufficient for the contained items.
• Always, as conduit bodies are designed for this purpose.
