Where should surge-protective devices (SPDs) be accessible to?

Surge-protective devices (SPDs) should be accessible to unqualified persons to ensure that individuals can easily reach and utilize them. This accessibility is important for maintenance and emergency situations, as users who may not have specialized training can still operate or reset the SPDs if necessary. Proper accessibility promotes safety and minimizes downtime in the event of a power surge or electrical fault.

In contrast, some other choices involve restrictions that would limit access. For instance, options that restrict access to only qualified personnel or suggest that only indoors related locations should house SPDs can hinder effective responses during critical moments. Restricting access can create barriers that could lead to prolonged outages or increased risk during surges, which contradicts the purpose of using SPDs effectively for protection against voltage spikes.
