Blackburn BTC3104-B2-5 – Frequently Asked Questions
1) What wire size does the Blackburn BTC3104-B2-5 copper terminal lug take?
The BTC3104-B2-5 terminal lug is rated for conductors from 3/0 AWG down to 4 AWG. That range covers a single conductor per lug, so one lug lands one cable. If your feeder is larger than 3/0 or smaller than 4 AWG, this is the wrong lug for the run.
2) Is the Blackburn BTC3104 lug a crimp lug or a mechanical set screw lug?
It's a mechanical, screw-type termination. You strip the conductor, insert it, and torque the set screw down. No crimp tool, no die set, no hydraulic press, which is why these get used for field terminations and panel work where dragging a crimper up a ladder isn't practical. If you need a compression connection, a set screw lug won't satisfy that spec.
3) Can I use a Blackburn BTC copper lug on aluminum conductors?
No. The BTC3104-B2-5 is a copper-bodied lug, so use it on copper conductors. Landing aluminum in a copper-only connector risks a galvanic problem at the joint. For aluminum or mixed copper/aluminum feeders you want a connector marked AL9CU dual-rated, not a copper-only body.
4) Does the BTC3104-B2-5 copper lug come with any insulation or cover?
It's a bare copper lug with no insulation on it. Anything covering the termination, heat shrink, an insulating boot, or the enclosure itself, is on you to supply and is not part of the lug. Plan that into the job if the landing is in an exposed or accessible location.
5) How many lugs do I get when I order one Blackburn BTC3104-B2-5?
The selling unit is each, so one order quantity gets you one lug as the unit of sale. On a three-phase feeder plus neutral you're buying four, plus whatever you need for the ground. Count your terminations, not your cable runs.
6) What is a Type BTC copper terminal lug actually used for?
A Type BTC lug is a single-conductor copper terminal connector, the piece that turns the end of a cable into a bolt-down pad so it can land on a bus, a breaker stud, a ground bar, or an equipment terminal. The BTC3104 handles one conductor between 3/0 and 4 AWG and fastens with a screw. If you need to join two cables to each other mid-run rather than land one on a pad, a splice or tap connector is the right family, not a terminal lug.
7) Will one BTC3104 lug land two conductors under it?
No. It's built for one conductor per lug. Doubling wires into a single-conductor terminal is a listing violation on most equipment. If you need two cables on one point, use a two-conductor (dual barrel) lug or land them on separate positions of the bar.
