Section 230.95 requires ground-fault protection for which kind of electrical services?

The requirement for ground-fault protection, as outlined in Section 230.95, specifically applies to solidly-grounded wye electrical services that have a voltage of more than 150 volts to ground. This specification is important because solidly-grounded wye systems are commonly used in various applications, including commercial and industrial settings, and can pose a significant shock hazard if ground faults occur. The requirement for ground-fault protection enhances safety by ensuring that any stray current is safely directed to ground, minimizing the risk of electric shock and fire.

This protection mechanism is essential for systems operating at higher voltages, as the potential for dangerous electrical conditions increases. The inclusion of ground-fault protection in solidly-grounded wye systems reflects a proactive approach to electrical safety, necessitating that these systems have adequate measures in place to detect and interrupt ground faults, thereby safeguarding both equipment and personnel.
