What are the requirements for surge protection devices?

Surge protection devices (SPDs) must be installed in accordance with National Electrical Code (NEC) standards when their use is dictated by the specific installation. This requirement ensures that SPDs are installed correctly to effectively protect electrical equipment from voltage spikes. The NEC outlines specific guidelines for installation, including location, type of SPD, and related protective measures to meet safety and reliability standards.

When SPDs are required as part of an electrical system, their proper implementation in accordance with the NEC standards ensures compliance with safety regulations and aids in the proper functioning of the device, ultimately protecting against surges that could damage sensitive electronics.

The other options do not align with standard practices outlined in the NEC. For example, suggesting that SPDs are optional in new constructions overlooks situations where they may be necessary for compliance and safety. Additionally, stating that there are no specific requirements dismisses the detailed guidelines set forth by the NEC, and implying that anyone can install these devices raises concerns about safety and proper installation practices that the NEC aims to regulate.
