Electrical design involves load calculations, circuit layouts, panel schedules, and wiring diagrams. It also considers energy efficiency and backup power solutions like generators and UPS systems. Lighting design, both interior and exterior, is planned to meet both functional and aesthetic needs. Proper grounding and short-circuit protection are essential for system safety.

Electrical engineers must coordinate with mechanical and plumbing teams to avoid clashes in system routing. For example, electrical conduits should not interfere with HVAC ductwork or plumbing pipes. Coordination ensures smooth installation and long-term maintenance. Electrical systems also often power mechanical equipment, making cross-discipline collaboration crucial.
