B-LINE SB47908 – Frequently Asked Questions
1) What wire size does the B-Line SB47908 grounding lug take?
The B-Line SB47908 grounding lug is sized for 3/0 conductor. It is a compression connector lug, so the conductor barrel is crimped onto the wire rather than set-screwed, which means you need a crimp tool and die matched to a 3/0 copper compression lug.
2) Do I need to buy separate bolts to mount this grounding lug?
No. Silicon bronze mounting hardware ships with the SB47908 grounding lug, so the bolt and nut for the pad connection are in the box. What is not included is the crimp die set for the 3/0 compression barrel, which you supply with your tool.
3) Can I use the SB47908 on aluminum grounding conductor?
It is a copper alloy lug rated for 3/0 wire, so keep it on copper conductor. Aluminum conductor needs a connector marked AL or AL9CU with the appropriate inhibitor compound; putting bare aluminum into a copper-only barrel is a code and corrosion problem.
4) What is the SB47908 lug made of, and will it corrode where it bolts to steel?
Body is copper alloy and the mounting hardware supplied with it is silicon bronze. Silicon bronze bolts are the usual choice on grounding connections because they resist galvanic corrosion against copper and hold torque outdoors or in damp vaults. Bolting copper directly to galvanized steel or aluminum is still a dissimilar-metal joint, so treat that contact surface accordingly.
5) Should I use a compression grounding lug or a mechanical set-screw lug?
A compression lug like the SB47908 is crimped permanently onto the conductor, so there is no set screw to back off from vibration or thermal cycling and nothing to re-torque on a maintenance schedule. That is why it gets specified for grounding risers, service grounds, and buried or hard-to-reach connections. A mechanical set-screw lug is the one to use when you want the conductor to be removable for testing or when you have no crimp tool on site. Compression is a one-shot install: size the die to 3/0 copper before you squeeze.
6) What is the part number to order for this B-Line grounding lug?
Order it as B-Line SB47908, the Eaton B-Line compression grounding lug for 3/0 copper with silicon bronze hardware. There is one configuration, so there is no finish or size suffix to specify.
