Rough-In vs Fit-Off Electrical: What Melbourne Builders Need to Know

Understanding the difference between rough-in and fit-off electrical is essential for any Melbourne builder. Getting the timing right keeps your project on schedule and avoids costly delays.

What is Rough-In Electrical?

Rough-in electrical (also called first fix or pre-wire) is the initial phase of electrical installation. It happens during the frame stage, before plasterboard goes up.

What's included in rough-in:

  • Cable runs through wall frames, ceiling joists, and floor spaces
  • Back box installation for power points, switches, and data outlets
  • Conduit installation for cable protection
  • Switchboard location preparation
  • Temporary power setup if required

For a standard Melbourne home, rough-in takes 2-4 days depending on size and complexity.

What is Fit-Off Electrical?

Fit-off electrical (also called second fix or final fix) is the completion phase where all visible electrical components are installed and connected.

What's included in fit-off:

  • Light switches and power points installation
  • Light fittings mounting and connection
  • Smoke detector installation
  • Exhaust fans connection
  • Appliance connections (oven, cooktop, rangehood, hot water)
  • Switchboard completion and labeling
  • Full circuit testing
  • Compliance certificate issue

The Right Sequence for Your Build

Getting the timing right between rough-in and fit-off is critical. Here's the correct sequence:

  1. Frame completion
  2. Rough-in electrical (2-4 days)
  3. Rough-in inspection
  4. Insulation
  5. Plasterboard
  6. Painting
  7. Fit-off electrical (2-3 days)
  8. Floor coverings
  9. Final inspection

Common Scheduling Mistakes

  • Booking rough-in too late — delays plastering and everything after
  • Not allowing for inspection — rough-in must be inspected before covering
  • Fit-off before painting — risk of damage to fittings
  • Missing appliances — delays final connections and certificates
