Service Entrance conductors are critical for bringing electricity from the utility supply into a building safely and effectively. Rigid Steel Conduit (RSC) and Intermediate Metal Conduit (IMC) are both strong and durable options that provide excellent protection for the wiring against physical damage and environmental conditions. Their robust nature makes them ideal for outdoor applications, which is often where service entrance wiring runs are located.

In specific installations, RSC/IMC also offers electrical grounding and can safely protect the wiring within, ensuring compliance with safety codes and regulations. The ability to withstand the elements and physical impacts makes RSC and IMC especially suitable for service entrance scenarios, where long-term reliability and safety are paramount.

While other conduit types like PVC, EMT, and Flexible Conduit each have their own applications, they may not provide the same level of physical protection or are not typically used in service entrance installations, which require heavy-duty solutions. Thus, RSC/IMC is the preferred choice.
