Bushing
A bushing is an important safety component in electrical installations that helps protect and insulate electrical connections where wires or cables pass through walls, transformers, or other equipment. Think of it like a protective sleeve or collar that prevents electrical problems and maintains proper spacing. Electricians use bushings to ensure installations are safe and meet building codes. You might see this term used interchangeably with "electrical bushing" or "insulator bushing" in resumes and job descriptions.
