Burndy CL501 Qiklug Copper Lay-In Lug, #14-4 AWG, #10 Stud

The Burndy CL501 is a copper lay-in lug from the Qiklug series, engineered to terminate conductors in the #14-4 AWG range using a #10 stud. Machined from copper for dependable conductivity, this open-faced mechanical connector is rated for direct burial, making it well suited to demanding grounding and bonding installations where a secure, code-compliant termination is required. The open-faced, lay-in design lets an installer set the conductor into the lug body without threading it through, speeding up field terminations on both new construction and retrofit grounding systems.

Key Features

  • Conductor Range: Accepts #14-4 AWG copper conductors for a wide range of grounding and bonding applications.
  • Stud Size: Fitted with a #10 stud for secure mechanical attachment to equipment or grounding points.
  • Copper Construction: Solid copper body delivers strong, corrosion-resistant electrical conductivity.
  • Open-Faced Lay-In Design: Conductors lay directly into the open-faced connector body, eliminating the need to thread wire through a closed barrel.
  • Direct Burial Rated: Suitable for direct burial installations, supporting underground grounding and bonding runs.
  • Unplated Finish: Bare copper finish for direct copper-to-copper connections.
  • Qiklug Series: Part of Burndy's Qiklug line of mechanical lay-in connectors.
  • Mechanical Connector Type: A mechanical-style grounding and bonding lug rather than a compression connector, allowing tool-free or minimal-tool installation.

Burndy CL501 – Frequently Asked Questions

1) What wire sizes will the Burndy CL501 Qiklug lay-in lug accept?
The CL501 takes copper conductors from #14 AWG up to #4 AWG, and that range covers both solid and stranded copper. So a #14 equipment ground pigtail and a #4 bonding jumper both terminate in the same lug, which is why it gets stocked as a general grounding lug rather than one size per conductor.
2) Can the CL501 lug be buried underground or set in a direct-burial grounding run?
Yes, the CL501 is rated for direct burial, so it can be used on underground grounding and bonding connections rather than only in dry enclosures. The body is solid copper and unplated, which keeps it to a copper-to-copper connection in the soil.
3) What size screw or stud hole does the Burndy CL501 mount with?
The CL501 mounts with a #10 stud, so the equipment ground pad, panelboard bar, or enclosure boss it lands on needs a #10 tapped hole or a #10 screw through it. If your grounding pad is drilled for 1/4-20 or larger, this is the wrong lug for that pad.
4) Can I use the Burndy CL501 on aluminum conductor?
No. The CL501 is a copper lug with an unplated bare copper finish, and its rated range covers copper conductors only, #14 through #4 AWG solid or stranded. For aluminum or for a mixed copper-to-aluminum termination you need a lug rated AL9CU or equivalent, not this one.
5) What is the difference between a lay-in lug like the CL501 and a compression lug?
The CL501 is a mechanical connector, not a compression one. The conductor lays into an open-faced body and is held by the screw, so you need no hydraulic or battery crimper and no die set, and the conductor does not have to be threaded through a closed barrel. That makes it quick for field terminations and for retrofits where the wire is already run and cut. A compression lug is the choice where the spec calls for a crimped, non-reversible termination.
6) Is the CL501 suitable for grounding a panelboard or a piece of equipment in a commercial building?
That is its normal use. It serves as a terminating point for equipment and panelboard grounding, bonding connections, and copper conductor terminations in commercial and industrial grounding systems, as long as the ground conductor falls in the #14 to #4 AWG copper range and the mounting point accepts a #10 stud.
7) Why is the CL501 lug bare copper instead of tin plated?
It ships unplated, which is a deliberate bare copper finish for direct copper-to-copper connections in grounding and bonding work. If your job spec calls out tin plating, for instance where the lug lands on an aluminum or dissimilar-metal pad, specify a plated lug instead.
8) What is the exact part number to order this Burndy Qiklug lay-in lug under?
Order it as Burndy CL501, from the Qiklug series of mechanical lay-in connectors. That is the manufacturer part number for the copper, unplated, #14-4 AWG lug with the #10 stud.
