Running an external ground on a Sealtite conduit provides several advantages

1. Improved Grounding Path:

- Sealtite is a non-metallic conduit that does not provide a direct electrical path to ground.- Running an external ground wire alongside the Sealtite creates a dedicated grounding path, reducing the resistance and improving the overall grounding system.2. Increased Safety

- A proper grounding system helps ensure the safe operation of electrical equipment.- By providing an external ground, it minimizes the risk of electrical shocks or damage to sensitive equipment in the event of a fault.

3. Electromagnetic Interference (EMI) Reduction

- Running an external ground wire helps to shield against EMI, which can interfere with the operation of electrical devices.- The ground wire acts as a barrier, preventing EMI from entering the conduit and affecting the equipment inside.

4. Compliance with Electrical Codes

- Many electrical codes require external grounding for non-metallic conduits.- Running an external ground ensures compliance with these codes and maintains a safe and code-compliant installation.

5. Lightning Protection

- In areas prone to lightning strikes, an external ground provides a low-resistance path for lightning currents to travel.- This helps protect the electrical system and equipment from lightning-related damage.

Installation Considerations:- The external ground wire should be of the same or larger gauge than the circuit conductors.- It should be secured to the Sealtite conduit at regular intervals using grounding clamps or straps.- The ground wire should be terminated at a suitable ground rod, grounding bus, or other approved grounding point.
