Thomas & Betts A18-6 – Frequently Asked Questions
1) What wire gauge does the Thomas & Betts A18-6 ring terminal take?
The A18-6 is sized for 22-16 AWG wire. If your conductor is 14 AWG or larger, this barrel won't accept it and you need a larger terminal in the series.
2) Will the A18-6 ring terminal fit a #6 screw or stud?
Yes. The ring tongue is drilled for a #6 stud, with the ring itself measuring 0.25 inch across the B dimension and a 0.27 inch C dimension. It will not seat on a #8 or #10 stud.
3) What crimp tool do I need for a Thomas & Betts A18 series terminal?
ERG4002 is the recommended tool. WT110M, WT111M, WT112M and WT2000 are also listed as application tools for it. A single-indentor crimp works; a double indentor is recommended when you're crimping solid wire.
4) I need a ring terminal for 6 AWG on a #8 or #10 stud. Is the A18-6 the right part?
No. The A18-6 tops out at 16 AWG and only fits a #6 stud. For 6 AWG on a #8-10 stud, look at the Burndy YAV6CL1BOX Hylug, a one-hole ring terminal built for that gauge and stud range.
5) Can a Burndy YAV6CL1BOX Hylug be used in place of a Thomas & Betts A18-6 ring terminal?
No, they serve different wire ranges. The Thomas & Betts A18-6 is a non-insulated ring terminal for 22-16 AWG wire with a #6 stud hole. The Burndy YAV6CL1BOX Hylug is a 6 AWG ring terminal with a single hole sized for a #8-10 stud, so it is a heavier conductor lug. For 22-16 AWG control or fixture wiring landing on a #6 screw, the A18-6 is the correct part; for a 6 AWG feeder conductor, the Burndy Hylug is the one that accepts the wire.
6) What should I use if my stud is a #8 or #10 instead of a #6?
The Thomas & Betts A18-6 is drilled for a #6 stud, so it will not pass over a #8 or #10 screw. The Burndy YAV6CL1BOX Hylug is a 1-hole ring terminal with a #8-10 stud hole, though it is sized for 6 AWG conductor rather than small-gauge wire. Confirm both the stud diameter and the conductor size before ordering, since a ring terminal has to match both.
7) Is this ring terminal insulated, and does that matter for my application?
Non-insulated. The A18-6 is bare electro tin-plated copper, so there's no nylon or vinyl sleeve to strain-relieve the wire or isolate the barrel. If adjacent terminals sit close together on a block, plan on heat shrink or use an insulated terminal instead.
8) What voltage and temperature is the A18-6 rated for?
600V and 150 degrees C. That covers typical control panel, fixture whip, and line-voltage device wiring, and the 150 C rating means it isn't the limiting factor next to standard building wire insulation.
9) Is the A18-6 ring terminal UL listed and RoHS compliant?
It carries both UL and CSA, is RoHS compliant, and is rated UL 94 V-0 for flammability. For institutional and government specs that call out UL plus RoHS on terminations, it meets both.
10) For panel terminations, how does the Thomas & Betts A series ring terminal differ from a Burndy Hylug?
The Thomas & Betts A18-6 belongs to the A terminal series: a non-insulated electrolytic copper barrel with electro tin-plated finish, serrated barrel for wire grip, rated 600V and 150 degrees C, crimped with a hand tool such as the ERG4002. The Burndy YAV6CL1BOX is from the Hylug series and is built for a 6 AWG conductor with a #8-10 stud hole. In practice the A series covers small-gauge terminations on tight stud sizes, while the Hylug covers larger conductor terminations.
11) How are these ring terminals packaged and what is the minimum order?
They're sold each, but ordered in multiples of 100. Inner pack is 100 pieces, outer carton is 500, and an alternate pack quantity of A85 is also catalogued. 100 pieces runs about 0.19 lbs.
12) How much room does the A18-6 need on a crowded terminal block?
Overall length is 0.72 inch with a 0.59 inch M dimension, and the tongue stock is 0.03 inch thick. That thin tongue matters when you're stacking two terminals under one #6 screw.
13) Why choose a serrated barrel ring terminal over a plain one?
The serrations inside the A18-6 barrel bite into the strands and increase grip, which helps the crimp hold under vibration. The body is electrolytic copper for conductivity, tin-plated for corrosion resistance at the contact face.
