Design explosion-protected electrical systems and installations

KHU-ELT-0311

This unit involves the skills and knowledge required to apply explosion-protection aspects in designing electrical power, control and instrumentation systems and installations for hazardous areas. It includes: understanding of the explosion-protection required for electrical installation for hazardous areas; determining the scope of the required electrical installation from hazardous area classification drawings, process specifications and plant design; documenting detailed specifications of compliant explosion-protected equipment and wiring systems, equipment locations, cable routes; and obtaining and interpreting the standards to which the installations need to comply. This unit applies to electrical, instrumentation and control engineering design job functions. Site-specific work permits may be required to work in the hazardous environment. In addition, other permits may be required,
