Blackburn STC3511 – Frequently Asked Questions
1) What wire sizes does the Blackburn STC3511 copper connector take?
The STC3511 is built for a single conductor in the 1/0 stranded through 350 range, which is what the "1/0STR-350" in the part designation calls out. It is a one-conductor lug, so each cable needs its own connector.
2) Is the STC3511 a one-hole or two-hole mount lug?
One hole. The STC3511 is a single-hole mount tang connector, so it lands on a single bolt or stud at the panel, bus, or equipment pad. If your pad is drilled for two-hole NEMA spacing and you need the anti-rotation that gives you, specify a 2-hole lug instead.
3) Can I use the Blackburn STC3511 on aluminum conductors, or copper only?
Copper only. It is a copper-bodied connector identified as CU, not a dual-rated AL9CU lug, so run it on copper conductors. For aluminum feeders you need a connector marked AL9CU or AL.
4) Is the STC3511 a crimp lug or a mechanical set screw connector?
Mechanical. The STC3511 is a mechanical set screw type connector, so you strip the conductor, insert it, and torque the screw. No crimp tool or die set required, which is why electricians reach for it on service and panel work where they do not want to haul a hydraulic crimper.
5) Is the Blackburn STC3511 UL listed?
Yes, it carries UL file E9809.
6) Does the STC3511 come as a single lug or in a multi-pack?
Sold each. One connector per unit, so for a three-phase-plus-neutral termination you would order four, one per conductor.
7) Where is the Blackburn STC3511 made?
Mexico. Useful if you are compiling country-of-origin documentation for an institutional or government submittal package.
