Consultant vs Contractor – Comparison
Consultant Contractor
Designs and plans systems Installs and executes systems
Advises and represents the client Executes on behalf of the project
Ensures compliance & safety Ensures proper workmanship
Supervises installation Performs installation
Combined Role (Design–Build / EPC)

In Design–Build or EPC projects, one firm may act as both electrical consultant and contractor, offering:

  • Single-point responsibility
  • Faster project delivery
  • Reduced coordination issues
  • Optimized system performance
summary
  • Electrical Consultant = Design, analyze, specify, supervise
  • Electrical Contractor = Install, test, commission, maintain
