Blackburn STC4102 – Frequently Asked Questions
1) What wire sizes does the Blackburn STC4102 lug accept?
The STC4102 is a one-conductor mechanical lug rated for 2 AWG stranded through 4/0 AWG stranded copper. One conductor per lug, so a parallel run needs one lug per conductor. Copper only, not dual-rated for aluminum.
2) Is the STC4102 a one-hole or two-hole lug?
One hole. The STC4102 is a single-hole mount lug with a tang, so it lands on a single bolt at the bus, panel ground bar, or equipment pad. If your bus is drilled for two-hole NEMA spacing, you want a two-hole lug instead.
3) Can I use the Blackburn STC4102 on aluminum conductor?
No. It is a copper connector and the range is specified in stranded copper. Put aluminum or an AL/CU run on a dual-rated connector instead.
4) Is the STC4102 lug UL listed for inspection sign-off?
It carries UL file E9809, which is the reference an inspector or a spec reviewer will ask for on a mechanical connector.
5) Is a mechanical lug like the STC4102 the right choice, or should I be using a compression lug?
The STC4102 is a mechanical (set screw) lug, so it terminates in the field with a hex key and no die set or crimper. That is the usual pick for service and MRO work, panel ground bars, and retrofits where you cannot get a hydraulic tool onto the conductor. Where a spec calls for a compression termination, or the connection is subject to vibration or will be sealed up permanently, a compression lug is the one to specify.
6) Is the STC4102 sold individually or in a box?
Sold each, one lug per unit. If you are landing four feeders in a panel, order four.
7) What is the exact part number and manufacturer for this copper lug?
Blackburn STC4102, MPN STC4102, with UPC 783786134267. Country of origin is Mexico.
