Understand the difference.

Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.

Symbols

Capacitor

A capacitor representation identifies a capacitive component or arrangement in a circuit. Polarised, non-polarised, adjustable and other variants need the appropriate representation and annotations. In power drawings a capacitor bank is a system assembly, rather than merely a scaled-up generic component mark.

A distinction that matters

A capacitor-bank representation does not identify every component of the assembled bank or establish its switching duty.

Bus

Symbols

Busbar

A busbar connects multiple power circuits to a common electrical node. In an SLD it is commonly represented as a line with feeder connections. The representation describes connectivity; physical conductor dimensions, enclosure, phase arrangement and current-carrying capabilities are separate equipment information.

A distinction that matters

A busbar is an electrical connection. Busbar trunking is a physical distribution system with model-specific enclosures and fittings.
