An Abbreviation Sheet is a reference sheet included in an electrical drawing set that explains the short forms (abbreviations) used throughout the drawings and documents.

It helps engineers, technicians, contractors, and reviewers clearly understand symbols, notes, and labels without confusion.

  • Saves space on drawings by using abbreviations
  • Makes drawings easier to read for new team members
