Introduction:

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

The course begins with the fundamental principles that always apply to ensure safety, the course then progresses through basic design procedures, inspection, 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 workshop 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

Objectives:

The delegate will gain a 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 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
