Burndy QA8CB – Frequently Asked Questions
1) What wire sizes does the Burndy QA8CB terminal accept?
The QA8CB takes copper conductors from #14 AWG through #8 AWG, and that range holds for both solid and stranded copper. One clamping screw covers the whole range, so the same lug works on a #14 solid ground pigtail and a #8 stranded feeder tap. It is a copper-only connector, so do not use it on aluminum conductors.
2) Is the Burndy QA8CB UL Listed for use in a panelboard?
It is UL Listed and built to the UL468A-468B industry standards for wire connectors, which is the listing an inspector looks for on a mechanical terminal landing copper in panelboards, switchgear, and grounding and bonding work. It is RoHS exempt. Note that it does not carry a CSA or cULus mark, so for a Canadian job you need a CSA certified connector instead.
3) What torque should I use on the QA8CB clamping screw?
Burndy rates the QA8CB at an installation torque of 75 in-lb on its single clamping screw. Use a torque screwdriver rather than feel: under-torquing a mechanical lug is the usual cause of a hot connection, and over-torquing can gall the copper body.
4) How much room does the QA8CB lug need inside a panel or gutter?
Overall it runs 1-3/8 inches long by 11/16 inch high, with a pad width of 0.56 inch and a tongue thickness of 0.16 inch. Allow clearance above that height for a screwdriver or hex key on the clamping screw. The narrow 0.56 inch pad lets you land several side by side on a ground bar without the tongues overlapping.
5) Is the Burndy QA8CB plated or bare copper, and does that matter outdoors?
It is unplated solid copper, no tin. That is fine for dry indoor gear, bus bars, and panel grounding. In a damp, coastal, or corrosive environment, or where the lug lands on an aluminum or plated bus, a tin-plated connector is the better choice because bare copper against dissimilar metal invites galvanic corrosion.
6) Can I crimp the Burndy QA8CB, or is it a set-screw lug?
It is a mechanical lug, not a compression lug. The conductor goes into the barrel and a single clamping element tightens down with one screw, so no crimp tool or die set is needed. That makes it the practical pick for field terminations and retrofits where you cannot get a hydraulic crimper into the enclosure.
7) Does the Burndy QIKLUG QA8CB work with Navy cable?
Yes. Alongside #14 to #8 AWG copper, the QA8CB is rated for Navy cable sizes 4 (1) Navy through 14 (140) Navy, which matters on shipboard and government MRO work where cable is specified by Navy size rather than AWG.
8) What is the exact part number to order this Burndy copper terminal by?
Order it as Burndy QA8CB, part of the QIKLUG line. It is a one-hole, #10 stud, unplated copper mechanical terminal for #14 through #8 AWG copper. Distributors cross-referencing should note the adjacent QIKLUG numbers differ by wire range and stud size, so confirm both before substituting.
