9.5 Bridging bars
For current ratings 250 A to 1600 A, bridging bars can be mounted for implementing an
upstream or downstream connection point. They serve as a bridge for the load-side
connection and they can be attached either on the top or bottom of the transfer switching
equipment.
The bridging bars for current ratings 250 A to 630 A and 800 A to 1600 A comprise one
bridging bar as well as the bolts, nuts and washers for mounting.
These must be ordered separately for connecting to the connecting terminals. Please note
here the section titled Connecting bridging bars on the load side (Page 42)
To install the device, 3 or 4 bridging bars must be mounted depending on the number of
poles.
