They size cables, transformers, switchgear and protection, prepare single line diagrams and load schedules, and make sure the design is safe and code compliant. The role sits in the design office. A good Electrical Design Engineer gets the load calculations right, coordinates protection properly and delivers drawings that procurement and site can build without queries.

Key responsibilities

  • Prepare single line diagrams, load schedules and cable sizing calculations for the project.
  • Size transformers, switchgear, cables, busbars and protection to the load and code.
  • Design earthing, lightning protection and internal lighting layouts for the facility.
  • Carry out protection coordination and set relay parameters for each feeder.
  • Prepare panel schematics, GA drawings, IO schedules and termination details.
  • Review vendor drawings and technical bids for electrical equipment.
  • Coordinate electrical with mechanical, piping and civil to avoid clashes.
  • Answer site and procurement queries and issue revised drawings.
  • Ensure the design meets Indian standards and statutory electrical requirements.

Requirements

  • Bachelor's degree or diploma in electrical engineering
  • Knowledge of IS and IEC electrical standards
  • Cable sizing and protection experience
  • 3 to 6 years in electrical design

Frequently asked questions

What does an Electrical Design Engineer do?

An Electrical Design Engineer designs the electrical systems for a plant, building or product. They prepare single line diagrams and load schedules, size cables, switchgear and transformers, do protection coordination, design earthing and lighting, and release drawings. Their job is a safe, code compliant electrical design that site can build without queries.

What is the difference between an electrical design engineer and a site electrical engineer?

A design engineer works in the office producing calculations, single line diagrams and drawings. A site electrical engineer installs, tests and commissions the systems at site and manages contractors. Design decides what to build; site makes it work in the field. The two coordinate through drawings and site queries.

What software does an Electrical Design Engineer use?

Common tools include AutoCAD Electrical for drawings, ETAP or DIgSILENT for load flow and protection studies, Dialux for lighting design and Excel for load and cable sizing. Familiarity with IS and IEC standards matters as much as the software, since the design must be code compliant.
