- Medium-voltage metal-enclosed bus above 600 V, which uses a different listing, dielectric design, and short-circuit basis (governed by IEEE C37.23)
- Low-ampere lighting busway (trolley duct), whose construction, ratings, and tap method differ fundamentally from power busway
−- The bus connections internal to switchboards, panelboards, transformers, or generators where busway terminates, which are governed by the standard for that terminating equipment (see [[syncs/low-voltage-switchboards]], [[syncs/low-voltage-panelboards]])

### An isolated ground bus keeps the clean ground reference independent of the housing, which carries circulating and fault currents; this matters for data and instrumentation loads. {note}
−### Grounding and bonding of the busway shall comply with [[syncs/grounding-and-bonding]] and NFPA 70 Article 250.
+### Grounding and bonding of the busway shall comply with [[sync/grounding-and-bonding]] and NFPA 70 Article 250.

## Labeling {toc}
−### Each busway run shall be labeled at its origin with the ampere rating, voltage, phase configuration, and source identification, in accordance with [[syncs/equipment-labeling]].
