- Ground-fault protection systemsNEC 230.95 (C) is a section of the National Electric Code that requires ground-fault protection systems to be performance tested when first installed on site123. The testing should be conducted by a qualified person using a test process of primary current injection, in accordance with instructions that shall be provided with the equipment1. The objective of the test is to identify how the system operates under various levels of current load2. The section applies to 480Y/277V, solidly grounded “wye” only connected service disconnects, 1000A and larger4.Learn more:âś•This summary was generated using AI based on multiple online sources.
