What is the primary purpose of conduit end caps?

The primary purpose of conduit end caps is to protect conduit ends from debris. Conduit end caps serve as a protective barrier that prevents dirt, moisture, and contaminants from entering the conduit, which can potentially damage the electrical wiring inside. By sealing the ends of the conduit, these caps help maintain the integrity of the electrical system, ensuring safety and reliability. This is particularly important in environments where conduits are exposed to external elements or contaminants.

The other options do not accurately reflect the function of conduit end caps. Enhancing conductivity or improving thermal dissipation is related to the properties of the materials used for the wiring and insulation but does not pertain to the physical caps themselves. While support for additional weight may be relevant in specific structural components, conduit end caps are not designed for structural support of the conduit. Thus, protecting the ends of the conduit from debris is indeed their main function.
