Electrical Installations & Maintenance

Design, Inspection/Testing, Maintenance and Resilience


This LAKESHORE ISL Electrical Installations & Maintenance training seminar begins with the fundamental principles that always apply to ensure safety. This Electrical Engineering training course then progresses through basic design procedures, inspection and testing and maintenance requirements, concluding with a review of power quality problems that affect the reliability of an installation where high technology interfaces with a supply.

The electrical designer, installer and maintenance team are all expected to provide an installation that is safe, cost effective and reliable throughout its lifetime.

This LAKESHORE ISL training course will provide an understanding of:

  • The initial assessment of an installation prior to the design
  • Selection of protective devices
  • Cable sizing and installation
  • Inspection and testing procedures
  • The maintenance requirements


The delegate on this LAKESHORE ISL training seminar will gain detailed appreciation of:

  • The safety factors required by national and international standards
  • The functional considerations that a designer has to take into account
  • How new technology can impact on the design particularly power quality
  • Safety requirements during installation, inspection and testing
  • Inspection and testing techniques that affect the maintenance requirements
  • How to improve productivity by improving the reliability of an installation

Training Methodology

This LAKESHORE ISL Electrical Installations & Maintenance training seminar is conducted as modular lectures with encouragement for the delegate to interact. Case studies are included to illustrate how problems can develop as technology changes.

A design project is included in this LAKESHORE ISL Electrical Engineering training seminar to enable the delegate to practice the techniques of calculating the parameters of loads, protective devices and cable sizing for safety and functional purposes. Questions are welcomed throughout this LAKESHORE ISL training programme and during break sessions.

Organisational Impact

  • The additional knowledge will help in the design of new electrical installations
  • This knowledge will help in upgrading an existing installation when new technology is to be added
  • The training course will help an organisation to improve its effectiveness in ensuring compliance with standards
  • Knowledge of the impact of new technology will help in ensuring reliability of an installation
  • Knowledge of the design implications to withstand failures due to power quality
  • How inspection, testing and maintenance improve the resilience of an installation

Personal Impact

On successful completion of this LAKESHORE ISL training seminar, delegates will understand:

  • The basis for safety and functional design
  • How to assess the characteristics needed to commence a design process
  • The earthing and bonding requirements of an installation for safety and function
  • How new technology impacts on new and existing electrical installations
  • Inspection and testing techniques that affect the maintenance routine of an installation
  • How to improve productivity by improving power quality

Who Should Attend?

This LAKESHORE ISL training programme is aimed at personnel who would like to expand their knowledge of the safety and functional design of an electrical installation and is aimed at:

  • Mechanical and Electrical Engineers
  • Mechanical and Electrical Technicians
  • Electricians
  • Maintenance Personnel with responsibility for an Electrical Installation

Seminar Outline


Preliminary Design Requirements

The design process requires consideration of the installation requirements with respect to the load characteristics, the circuit arrangements, and the source of supply.

  • Building Services
  • Purpose of an Installation
  • Cables
  • External Influences
  • Transformers
  • Compatibility
  • Protective Devices
  • Maintainability


Design Characteristics

To enable work to begin on any electrical installation a detailed specification is required. This specification will be based on the safety and functional requirements considered in DAY 1.

  • Electrical Safety
  • Cable Installation
  • IEC 60364
  • Terminations
  • Wiring Regulations
  • Inspection and Testing
  • Cable Sizing
  • Documentation


Designing an Installation

Building on the first two days of the training course, this module puts into practice the theories developed.

  • Single Phase Design
  • Power Quality
  • Three Phase Design
  • Cable Requirements
  • Protective Device Selection
  • Installation Method
  • Earthing and Bonding
  • Source of Supply


Commissioning and Testing

The requirements for any maintenance routine begin during the design process and continue through installation into operation. In many countries, there is also a legal requirement to maintain an installation in a safe condition.

  • The Need to Maintain
  • Test Results
  • What is Maintenance?
  • Documentation
  • Introduction to Commissioning
  • Harmonics
  • Inspection
  • Earth Leakage


Periodic Maintenance

After the initial verification of the safety and function of the installation, it is necessary to ensure that safety remains effective throughout the lifetime of the installation.

  • Maintenance Planning
  • Periodic Inspection
  • Equipment Reliability
  • Complex Testing
  • Categories of System
  • Harmonic Analysis
  • Safety Critical
  • Records
