Proper installation is critical for safety and must adhere to national electrical codes. While specific rules vary, these general principles are universally applied:

1. Sizing the Conductor:

   • GEC Sizing: The GEC is sized based on the size of the service-entrance conductors, not the circuit breaker size. A larger service requires a larger GEC.

   • EGC Sizing: The EGC is sized based on the rating of the overcurrent protective device (the circuit breaker or fuse) protecting the circuit. A higher-amperage circuit requires a larger EGC.

2. Connections:

   • Connections to the grounding electrode must be made with a listed, non-corrosive clamp or by exothermic welding (a process that creates a permanent, molecular bond).

   • All connections must be secure and made to provide a continuous, low-resistance path.

3. Physical Protection:

   • Grounding conductors must be protected from physical damage, especially when exposed.

   • Depending on the conductor size, it may need to be run in a protective conduit.

4. Continuity:

   • Both the GEC and EGC must be installed in a single, continuous length without splices or joints unless specifically allowed by code.

As a manufacturer of professional-grade equipment for power line and substation construction, we understand that every detail of an electrical project—including the grounding system—is vital for a safe and reliable outcome.
