B-LINE SB47902 – Frequently Asked Questions
1) What is the B-Line SB47902 grounding lug used for?
The B-Line (Eaton) SB47902 is a compression connector lug for terminating a ground wire onto a grounding bus. It is a crimp-on copper alloy lug, not a set-screw mechanical lug, so it requires a compression tool and die rather than a hex key.
2) Is the SB47902 grounding lug UL Listed for use in a telecom or data center ground bar?
The SB47902 compression lug is UL Listed, which is what most facility and inspection specs call for on grounding terminations. It is intended for bonding a ground conductor to a grounding bus bar.
3) Does the SB47902 come with mounting bolts, or do I order hardware separately?
Silicon bronze hardware is offered in additional sizes for these B-Line grounding accessories, so the bolt, nut and washer set is a separate selection matched to your bus bar hole size and thickness. Order the lug and the bronze hardware together so you are not improvising with plated steel fasteners on a copper bus.
4) Can I use a mechanical set-screw lug instead of the SB47902 compression lug?
You can, but they are different installs. The SB47902 is a compression connector lug, crimped onto the conductor with a die set, giving a permanent termination with no screw torque to re-check. A mechanical set-screw lug installs with hand tools and can be reused, which suits field changes or when no crimper is on site. Spec drawings for grounding risers and telecom bus bars often call out compression specifically.
5) Will a copper alloy grounding lug corrode against a copper ground bus?
No. The lug body is copper alloy, so it is metallurgically compatible with a copper grounding bus and avoids the dissimilar-metal galvanic problem you get pairing aluminum lugs to copper bar. Pairing it with silicon bronze hardware rather than plated steel keeps the whole joint compatible.
6) I need to ground several different conductor sizes on one bus bar. Is the SB47902 the only option?
The SB47902 is one size in a B-Line grounding accessory range that is offered in additional sizes, so a run of different conductor gauges is handled by ordering the matching lug for each rather than forcing one barrel size. Compression lugs are conductor-size specific, so match each lug to the wire it terminates.
7) What part number do I order for this B-Line grounding lug?
Order B-Line (Eaton) model SB47902. That is the manufacturer part number for the UL Listed copper alloy compression grounding lug.
