Display shows E08; charger will not start and may indicate ‘Ground Missing’ or ‘Protective Earth Fault’.

Safety first: Do not operate the charger without a verified equipment ground. Turn OFF the breaker.

Steps:

• Check ground conductor: At the Lucid charger input, verify the green or bare ground wire is present and firmly secured to the ground terminal.
• Inspect ground lug: Ensure the internal ground bus or lug in the Lucid unit is tight and free of corrosion.
• Panel inspection (electrician): Have a licensed electrician verify that the branch circuit ground is continuous back to the service panel and properly bonded.

Resolution: Once a solid ground path is restored and all terminations are tightened to spec, power-cycle the Lucid charger. If E08 persists, the internal ground monitoring circuit on the control board may be faulty and require replacement.
