B-LINE SB57904 – Frequently Asked Questions
1) What is the B-Line SB57904 ground bar used for?
The B-Line Eaton SB57904 is a universal copper ground bar used as a rack mounted equipment grounding bus. It gives you a single bonding point inside a relay rack or cabinet that all the equipment grounding conductors terminate to, rather than running individual grounds back to the panel.
2) Is the SB57904 ground bar UL Listed for use in a data center or institutional install?
UL Listed, which is what most facility electrical specs and AHJ reviews ask for on a grounding bus. The bar itself is copper with a yellow zinc plated finish on the hardware.
3) What hardware comes with the B-Line SB57904 ground bar?
A splice plate and a yellow zinc plated lock washer ship with the bar. The splice plate is what lets you join bars end to end to extend the bus down a longer rack or across a row of cabinets. Lugs, mounting brackets, and insulators for the rack are separate items, so check what your grounding detail calls for.
4) Is this a solid copper ground bar or a plated steel bus bar?
The bar is copper, not plated steel. That matters for a grounding bus because copper keeps the connection resistance low and mates properly with copper grounding conductors and compression lugs without the dissimilar metal issues you get bonding copper to a steel bus.
5) How heavy is the SB57904 ground bar, and can one person mount it?
It weighs 1.2 lb, so a single installer can hold it in place and start the fasteners without a second set of hands. The mass is in the rack hardware and lugs, not the bar.
