What does Article 285 focus on?

Article 285 specifically addresses Surge-Protective Devices (SPDs) rated for 1 kV or less. The inclusion of this focus highlights the importance of safeguarding electrical systems from voltage surges, which can occur due to various reasons such as lightning strikes or equipment switching. By establishing guidelines for the installation, use, and testing of SPDs, Article 285 ensures that electrical installations maintain a level of protection against transient voltage spikes, thus enhancing overall system reliability and longevity.

Understanding the details covered in this article is crucial for electricians and engineers who work on designing and implementing electrical systems that require adequate surge protection. It encompasses the types of devices, their ratings, and installation requirements, thereby providing a framework that professionals can follow to comply with safety regulations while minimizing the risk of damage or failure caused by unexpected voltage increases.

Awareness of the content in Article 285 is essential for ensuring that installations not only adhere to code requirements but also protect sensitive equipment from surge-related failures effectively.
