Which annex is described as informational and pertains to SCADA systems?

• A. Annex G
• B. Annex E
• C. Annex F
• D. Annex H

Answer: (A)

Informational annexes provide background material and guidance that isn’t enforceable as a requirement. Annex G is the one that focuses on SCADA systems, giving descriptions, context, and guidance for how these systems relate to electrical installations. Because it’s labeled informational, it’s intended to inform planning and understanding rather than mandate specific code obligations. SCADA (supervisory control and data acquisition) systems involve monitoring and controlling equipment and processes, so Annex G offers relevant information about integrating this topic into electrical designs without imposing mandatory rules. The other annexes cover topics in different areas and are not the SCADA-focused informational reference.
