## Spare parts shall be identical to and interchangeable with the installed parts, shall be delivered in their original packaging, and shall be labeled with the busway series, the rating, and the run designation they serve.
## Spare plug-in units are furnished under [[sync/feeder-busway-plug-in-units]]; the spares under this standard are the parts that let a joint be remade or a run be extended without waiting on the manufacturer's lead time. {note}
