Ground-fault protection of equipment must be performance tested when first installed on site?

Ground-fault protection of equipment is a critical safety measure designed to prevent electrical shock and equipment damage by detecting ground faults and interrupting the circuit. When ground-fault protection systems are first installed on-site, it is essential to conduct performance testing to ensure that the system functions correctly and meets safety standards. This initial testing verifies that the protection mechanisms respond appropriately to ground faults and operate as intended in real-world conditions.

Performing this testing upon installation is part of ensuring that equipment will function safely and effectively over its operational life. It helps identify any issues that may have been introduced during installation or commissioning, allowing for corrections before the equipment goes into service. Regular testing and maintenance are also recommended to keep the systems reliable, but the initial performance testing is a critical step in establishing confidence in the system's functionality from the outset.
