Electrical distribution systems

1 AIA CES approved LU available for attendees upon successful completion of an exam

It is useful for both electrical and nonelectrical engineers to understand basic features when selecting, specifying and applying electrical distribution systems. To narrow the broad scope of electrical distribution, this discussion will focus on practical considerations for specifying electrical distribution systems.

The discussion will focus on common low-voltage 480/120-volt electrical distribution equipment encountered in most facilities and will touch on medium-voltage equipment. Also, basic considerations for rooms housing these pieces of electrical equipment will be highlighted.

Learning objectives:

  • Understand basic features when selecting and specifying electrical distribution equipment.
  • Know the types of overcurrent protection devices (molded case circuit breakers, insulated case circuit breakers, low-voltage power circuit breakers and fuses) and switchgear as it is outlined in UL 1558.
  • Glean a basic understanding of panelboards, transformers and other electrical equipment.
  • Understand basic room and space requirements for the electrical equipment.
