What type of systems does Article 692 cover?

Article 692 specifically addresses Fuel Cell Systems, which are utilized for converting chemical energy from fuels, such as hydrogen, directly into electricity through an electrochemical reaction. This article includes regulations concerning their design, installation, and maintenance to ensure safety and efficiency in operation.

Fuel cell technologies can provide reliable power for various applications, including stationary, portable, and transport power generation. Understanding the intricacies of fuel cell systems according to the standards set forth in Article 692 ensures that electricians and engineers can effectively navigate the unique challenges and requirements these systems present.

In contrast, the other choices refer to different areas of electrical systems. Wind Electric Systems are covered under their specific articles, which focus on different regulatory aspects, while Energy Storage Systems typically align with other relevant codes and standards. Emergency Systems also fall under separate regulations that pertain to backup power solutions. Each of these types of systems has distinct characteristics and regulatory frameworks, which is why it's clear that Article 692 is dedicated to Fuel Cell Systems alone.
