14. GROUND FAULT SITE TEST REQUIREMENTS
Per NEC and UL1008, a ground fault protected system shall be performance tested when first installed
on site. A written record of this shall be made and be available to the authority having jurisdiction. A
form is provided at the back of this manual for this purpose – see SECTION 22.
Confirm and record actual trip set points in the form provided which is to be made available on request
by inspection authority.
14.1. PERFORMANCE TEST
Qualified Field Service technicians require a calibrated current injection test apparatus and
must be knowledgeable in breaker testing to provide primary neutral CT injection up to or
greater than the trip set point as selected by the responsible party. As indicated in the NEC,
