B-LINE SBCL4 – Frequently Asked Questions
1) What wire size do the Eaton B-Line SBCL4 compression lugs take?
The SBCL4 is sized for 4/0 conductor and has a two hole pad. It's a long barrel compression lug, so it gets crimped onto the conductor with a compression tool and die rather than tightened with a set screw. If your grounding conductor is a different size than 4/0, this is the wrong lug, since compression barrels are size specific.
2) Can I install these grounding lugs with a wrench, or do I need a crimper?
You need a hydraulic or battery crimper with the right die. These are long barrel compression lugs, not mechanical set screw lugs, so there is no way to terminate them by hand. If your crew doesn't carry a compression tool, a mechanical grounding lug is the better choice for that job.
3) Are the B-Line SBCL4 lugs meant for grounding or for power connections?
These are grounding lugs. Eaton B-Line lists them for connecting electric grounding wire, and the two hole pad is the usual arrangement for bonding to a ground bar, rack, or structural steel where a single bolt would allow the lug to rotate.
4) How many lugs come in a pack of B-Line SBCL4, and do I get hardware with them?
SBCL4 ships as a 10 piece pack, listed at 20 lb. Bolts, washers, and antioxidant compound are not part of the pack, so order the mounting hardware to match the pad hole spacing and the ground bar you're landing on, plus the correct compression die for a long barrel 4/0 lug.
5) Is a two hole lug required for grounding, or will a one hole lug do?
For rack and equipment bonding, two hole pads are the standard practice because two bolts keep the lug from spinning and hold the contact pressure. The B-Line SBCL4 is a two hole 4/0 lug for that reason. Single hole lugs are generally kept to less critical bonds.
6) Why tinned copper instead of plain copper on a ground lug?
The SBCL4 body is tinned copper. The tin plating slows galvanic corrosion where the copper lug lands on a different metal, which is the normal case in a telecom or data center ground ring bonding to aluminum or galvanized steel rack framing. Electrically it is still a copper connector.
