### Main bus continuous current rating shall be [[drawing: as indicated on the one-line diagram]].
+### Main bus continuous current rating shall be as indicated in the datasheet.
### Bus shall be braced for the available short-circuit current at the point of installation as determined by a short-circuit analysis per IEEE C37.010.
113 unchanged lines
### Rear access is the standard configuration for metal-clad switchgear because primary cable terminations, main bus connections, and section splices are located in rear compartments. Front-only access configurations are available from some manufacturers but typically require additional vertical depth in the breaker cubicle and limit cable termination options. {note}
### Switchgear overall dimensions, section count, and arrangement shall be [[drawing: per the equipment room layout drawings]].
+### Switchgear overall dimensions and arrangement shall be [[drawing: as indicated on the contract documents]].
### Coordinate section count and overall length with shipping splits to ensure equipment can be transported to and through the installation pathway.
710 unchanged lines
## Spare breakers shall be stored on a breaker handling/lift truck supplied by the manufacturer, located in the electrical room or substation control building.
