Blackburn STC1102 – Frequently Asked Questions
1) What wire sizes does the Blackburn STC1102 lug accept?
The STC1102 is a one-conductor copper mechanical lug rated for 2 STR through 1/0 STR conductors, per its catalog designation CU 1CNDTR 1HL MNT TANG 2STR-1/0STR. It takes stranded copper only in that range, so if you are landing anything smaller than 2 AWG or larger than 1/0, this is the wrong lug.
2) Can I use the Blackburn STC1102 with aluminum conductors?
No. The STC1102 is a copper-bodied mechanical connector built for copper conductors (the CU prefix in the part designation). For aluminum or dual-rated work you need an AL9CU-marked connector instead.
3) How does the STC1102 mount to a panel or ground bar?
It is a one-hole mount tang lug, so it lands on a single bolt or stud through the tang and terminates one conductor. One hole means it can rotate under load until the bolt is fully torqued, so hold the lug square to the bus while you tighten. If your bus prep is two-hole NEMA spacing, this lug will not match it.
4) Is the Blackburn STC1102 UL listed?
Yes, it carries UL file E9809.
5) Do I need a crimp tool or hydraulic press to install the STC1102?
No. It is a mechanical connector, so the conductor is captured by a setscrew, not compressed. A hex key or screwdriver and a torque wrench is all the install takes, which is why these get used for field terminations and service work where a crimper is not on the truck.
6) Is the STC1102 sold individually or in a bag of multiples?
Sold each. Part number STC1102 from Blackburn, so order by the piece count you need to land.
7) Where is the Blackburn STC1102 made?
Manufactured in Mexico. That matters for anyone with a Buy American or domestic-content clause on a government or institutional job, so check your spec before submitting it.
