Under what condition do the provisions of ground-fault protection of equipment not apply to a service disconnect?

The provisions of ground-fault protection of equipment do not apply to a service disconnect in circumstances where non-orderly shutdown introduces additional hazards. This means that if shutting down the service disconnect in a non-orderly manner could lead to greater risks or safety issues, then the ground-fault protection requirements may be waived.

This is critical because maintaining operational safety is paramount, especially in environments where sudden shutdowns could create dangerous situations. For instance, in industrial settings where equipment needs to remain energized to prevent hazards associated with sudden stoppages, the focus shifts from strictly adhering to ground-fault protection to managing operational risks.

The other choices do not accurately reflect conditions under which these provisions might not apply. For instance, residential applications typically require such protections to ensure users' safety, while temporary power installations and maintenance activities usually focus on safety and reliability, rather than allowing for the bypass of grounding rules.
