B-Line Eaton grounding lug, 1.1" height, 2.88" length, 0.8125" width, For connection of electric wire to grounding bus, Copper, Copper alloy, Two-hole

The B-Line (Eaton) SB47804 is a two-hole mechanical lug for landing an electrical wire onto a grounding bus. It is a compression-free connection: the conductor is clamped mechanically, and the lug body bolts to the bus through two holes rather than one, which keeps the lug from rotating under torque or vibration. It is UL Listed.

Yes, the SB47804 lug carries a UL Listing. That is the line item most institutional and MRO inspectors look for on grounding hardware, and it is stated on the part.

The lug body is copper alloy and the hardware is silicon bronze. Copper alloy on a copper ground bus is a like-metal connection, so you avoid the dissimilar-metal corrosion you get pairing aluminum-bodied lugs to copper bus. Silicon bronze bolts and nuts resist corrosion and hold torque better than plated steel in damp or outdoor enclosures.

A two-hole lug like the SB47804 bolts down at two points, so the lug cannot pivot when the conductor is pulled or when the bolt is torqued. Single-hole lugs are quicker and fine on light branch grounds, but two-hole is what you want on a main bonding jumper, equipment ground to a bus, or any run where movement or vibration could loosen the joint. Check your bus hole pattern first, since a two-hole lug only lands where the bus is drilled to match.

Yes, silicon bronze hardware is part of the assembly, so you are not sourcing separate bolts and nuts to land it on the bus. You still supply nothing beyond the conductor itself.

An additional size of this lug is offered alongside the SB47804. If the conductor you are landing is larger or smaller than what this body takes, ask for the alternate size in the same silicon bronze two-hole configuration rather than forcing the wire into this one.
