Electrical Installation Design and Testing

Electrical design engineer in Macedonia for installation design and testing, with insulation, earthing, fault-loop and RCD reports.

Focus

  • Installation design
  • Installation testing
  • Measurement reports

Tools used

  • AutoCAD
  • Eplan
  • Dialux

Key objectives

  • Prepare design documentation for electrical installations

  • Size circuits, protection and lighting to the real load

  • Test the finished installation before it is put into use

  • Issue measurement reports for the tests performed

Approach

  1. 01

    Review the building, the load and the supply point

  2. 02

    Prepare drawings and specifications in AutoCAD, Eplan and Dialux

  3. 03

    Coordinate protection with the upstream supply

  4. 04

    Test insulation resistance, earthing, fault-loop impedance and RCDs

  5. 05

    Record the results in a measurement report

Design

Design work is carried out under Authorization A for project documentation in electrical engineering, no. 4.1320, issued on 18.03.2025 by the Chamber of Authorized Architects and Authorized Engineers. It is valid until 17.03.2030, provided the annual membership fee is paid. The public record is the Chamber member profile. An electrical design engineer in Macedonia uses that authorization to prepare drawings and specifications for electrical installations.

The design covers circuit layout, protective devices, earthing and lighting. Drawings are prepared in AutoCAD and Eplan. Lighting calculations are prepared in Dialux.

Testing

Testing checks that the installation that was built matches the design and that the protective devices operate. The tests are:

  • Insulation resistance
  • Earthing resistance
  • Fault-loop impedance
  • RCD tests

Results are written into a measurement report. The report states what was tested, the measured values and whether each result meets the applicable technical rules in North Macedonia.

Installation protection has to coordinate with the supply. That work is described under relay protection testing and coordination. Disputes about installation quality are covered under electrical expert witness.
