Blackburn STC5011 – Frequently Asked Questions
1) What wire sizes does the Blackburn STC5011 lug accept?
The STC5011 is rated for conductors from 1/0 stranded up to 500 kcmil, and it takes one conductor per lug. If your feeder is smaller than 1/0 or larger than 500 kcmil, you need a different catalog number in the series.
2) Is the Blackburn STC5011 a one-hole or two-hole lug?
One hole. It is a single-conductor, one-hole mount tang terminal, so it lands on a single bolt at the bus, panel pad, or ground bar. If the pad on your equipment is drilled for two bolts on standard NEMA spacing, you want a two-hole version instead.
3) Can I use the Blackburn STC5011 on aluminum conductors?
No. The STC5011 is a copper-bodied connector specified for copper conductors only. For aluminum or dual-rated work, use a connector marked AL9CU.
4) Do I need a crimp tool for the Blackburn STC5011?
No crimping. The STC5011 is a mechanical connector, so the conductor is landed under a set screw and torqued down with a hex key or torque screwdriver. That makes it practical for field terminations where a hydraulic crimper is not on the truck, and it can be backed off and re-landed if a conductor has to be pulled.
5) Is the Blackburn STC5011 sold individually or in a box?
Sold each, one lug per unit, so you order the exact count for the number of terminations on the job rather than a fixed carton.
6) What is the country of origin on the Blackburn STC5011 copper lug?
Mexico. Useful if your project carries country-of-origin reporting on submittals or a government procurement requirement.
