WebFig. 6. Ground faults on ungrounded systems Another area of consideration is continuity of service. A high resistance grounded system limits the ground fault current to a value only slightly higher than an ungrounded system. These values are small enough that it is acceptable to not trip safety devices and let faults remain on the system. The Webthe equipment or the wiring system with a grounding electrode or electrodes.

WebFor solidly or functionally grounded PV systems OCPD was required on one leg of a PV circuit. By comparison, ungrounded PV systems required both legs of the PV circuit to have OCP. In recognizing that no new PV system is solidly grounded we can consolidate the design criteria for all new PV systems under NEC 2024. WebJul 19, 2006 · An ungrounded system has no intentional connection to ground with respect to its current-carrying conductors. Ungrounded systems are commonly distributed in a 3-phase, 3-wire delta configuration. On low voltage systems, typical system voltages are three-phase 240, 480, or 600 volts.
