What does Article 285 focus on?

Article 285 of the National Electrical Code specifically addresses Surge-Protective Devices (SPDs) rated for 1 kilovolt (kV) or less. This article outlines the requirements for the installation and use of SPDs, which are essential for protecting electrical systems and equipment from voltage spikes caused by lightning strikes, utility switching, or other disturbances.

The focus on SPDs in this article is vital because these devices help to prevent damage to electrical components, maintaining the integrity and reliability of electrical systems. It also ensures safety standards are met so that these devices can effectively mitigate risks associated with surges. The inclusion of specific provisions and guidelines in Article 285 reflects the importance of surge protection in today’s electrical infrastructure, which is heavily reliant on sensitive electronics.

In contrast, the other options pertain to different aspects of electrical installations and do not align with the specific content of Article 285. Conductors for lighting applications, armored cable properties, and integrated gas spacer cables are covered in other articles within the NEC.
