Blackburn CULL4-14TP – Frequently Asked Questions

1) What wire sizes does the Blackburn CULL4-14TP lay-in lug accept?
The Blackburn CULL4-14TP lay-in grounding lug takes copper conductors from 14 AWG up to 4 AWG. That covers the usual range you'd run for equipment grounding conductors in a panel or on a piece of gear, so one part number handles a #12 ground on a branch circuit and a #4 service-size ground alike.
2) Can I use this grounding lug with aluminum wire?
No. The CULL4-14TP is rated for copper conductors only, so an aluminum or copper-clad aluminum ground wire needs a different lug that is dual rated AL/CU. Using a copper-only lug on aluminum risks a bad connection at the termination.
3) Why choose a lay-in lug instead of a crimp or compression connector for a ground?
A lay-in lug lets you drop the conductor into the open channel and tighten the setscrew, so you don't need a crimp tool, a die set, or an exothermic mold. That is the difference on a retrofit where the ground wire is already run and you can't thread a conductor through a closed barrel. The CULL4-14TP is a mechanical grounding device, so the connection is made by clamping pressure rather than compression or welding, and it can be loosened and re-terminated if the wire has to be moved.
4) Is this Blackburn grounding lug UL listed?
It is built to UL E9809. That is the standards reference published for the CULL4-14TP, and it's the number an inspector or a spec reviewer will want to see cited on a grounding termination.
5) Will this lug work for bonding an equipment ground in a commercial panel?
Yes, that's the core use. A lay-in ground lug of this type terminates the equipment grounding conductor to a panel can, an enclosure, a piece of industrial equipment, or a service panel, anywhere you need a mechanical bonding point for a #14 through #4 copper ground. Confirm the mounting hole in your enclosure matches the lug's fastener before you commit to a quantity.
6) What does the tin plating on this Blackburn lug actually do for me?
Tin plating is a corrosion barrier over the body of the lug. It matters in damp, outdoor, or chemically aggressive spots, wet locations, exterior panels, pump rooms, where a bare finish would oxidize at the contact surface over time. Electrically the lug is still a copper-conductor device; the plating protects the mating surface so the connection stays low resistance.
7) Is the CULL4-14TP insulated?
No, it's a bare mechanical lug with no insulation on the body. For a grounding conductor that is normal and usually what you want, but if you are terminating inside a crowded enclosure where the lug could contact an energized part, plan the placement or add a boot yourself.
8) Is the Blackburn lay-in lug sold individually or in a bag of multiples?
It is sold each, one lug per unit, so order the exact count your panel schedule calls for rather than buying a pack and carrying leftovers.
9) Where is the Blackburn CULL4-14TP grounding lug made?
Country of origin is India. That's the detail procurement teams with domestic-content or trade-compliance requirements on a project need up front, before the submittal goes in.
