This role involves designing and planning complete electrical systems for industrial projects. It includes calculating power requirements, selecting equipment like transformers, panels, and cables, and preparing drawings such as SLDs and layouts. The work also covers choosing automation systems (PLC/SCADA) and ensuring safety standards are met. Additionally, it involves supporting installation, troubleshooting issues on-site, and preparing material lists (BOM). Overall, it’s about ensuring a safe, efficient, and reliable power system from design to execution.
