Blackburn CULL4-14-B2-10 – Frequently Asked Questions
1) What wire sizes does the Blackburn CULL4-14-B2-10 lay-in lug accept?
The CULL4-14-B2-10 takes conductors from No. 14 AWG up to No. 4 AWG, so it covers everything from small equipment grounding conductors through 4 AWG grounding electrode conductors on one part number.
2) Is the Blackburn CULL4-14-B2-10 lug copper or aluminum?
It is a copper lug (the CU in the part number), intended for copper conductors rather than aluminum or dual-rated AL/CU work.
3) Can I use the Blackburn CULL4-14-B2-10 to land an aluminum grounding conductor?
No. This is a copper-bodied lug listed for copper conductors. For aluminum or mixed aluminum and copper runs you need a dual-rated AL9CU lay-in lug instead, since landing aluminum in a copper-only connector is not a listed use.
4) What is a lay-in lug and why would an electrician pick one over a standard compression lug?
A lay-in lug has an open channel so the conductor drops in from the side and is captured by the set screw, instead of being threaded through a closed barrel or crimped. That matters on ground bonding work where the conductor is already run, continuous, or hard to feed, common on ground bars, enclosures, panel grounds, and equipment bonding. The CULL4-14-B2-10 is a copper lay-in lug covering 14 through 4 AWG.
5) Is the Blackburn CULL4-14-B2-10 sold individually or only in boxes?
Ordering is by the piece, with each lug sold as a single unit, so you can buy the exact count a panel or ground bar job needs.
6) Who makes the CULL4-14-B2-10 lay-in lug and where is it made?
It is a Blackburn part, catalog number CULL4-14-B2-10, manufactured in India. Distributors ordering against a spec should quote the full CULL4-14-B2-10 designation, since the numeric suffix identifies this specific 14 to 4 AWG copper version.
