AutoQuiz: Industrial Applications for Nonincendive-Rated Field Wiring

AutoQuiz is edited by Joel Don, ISA's social media community manager.

This automation industry quiz question comes from the ISA Certified Automation Professional (CAP) certification program. ISA CAP certification provides a non-biased, third-party, objective assessment and confirmation of an automation professional's skills. The CAP exam is focused on direction, definition, design, development/application, deployment, documentation, and support of systems, software, and equipment used in control systems, manufacturing information systems, systems integration, and operational consulting.

c) Class 1, Division 2; Class 1, Zone 1 and Class 1, Zone 2
d) Class 1, Division 2; Class 1, Zone 2 and Non-hazardous
