Compression Lugs One Hole
Upgrade switchgear, solar combiner boxes, and utility terminations with tin-plated copper one-hole compression lugs engineered for 8 AWG–1000 kcmil. Each lug is UL 486A-B and CSA approved, color-coded for industry-standard crimp dies, and stocked in standard or long-barrel designs for high-fault applications. Enjoy 105 °C ratings, 3–5 µm corrosion-resistant plating, and same-day shipping direct from our Wyoming warehouse—delivering premium performance at prices that out-crimp legacy brands.
One-Hole Compression Lugs — Conversions Tech™ vs. Burndy, Panduit, Thomas & Betts, ILSCO & Nicopress
Shop UL 467 / UL 486A-B listed copper and aluminum compression lugs engineered by Conversions Tech™ for switchgear OEMs, solar EPCs, utility substations, and commercial electricians. The plus/minus FAQ below shows how our lugs out-spec legacy brands on crimp window length, tin-plated corrosion life, and cost-per-termination.
Are Conversions Tech one-hole lugs UL and CSA certified?
Yes — all sizes from 8 AWG up to 1000 kcmil carry UL 486A-B and CSA C22.2 #65, meeting NEC 110.14 for copper conductors.
What conductor range do you stock?
We inventory 8 AWG through 1000 MCM in both standard and long-barrel “LBC” versions; competitors often stop at 750 kcmil.
Do Conversions Tech lugs accept fine-strand flexible cable?
The Flex-Max™ series is ASTM B172 Class K/M compatible and color-coded per UL 486D — Burndy’s YAV-FX and Panduit FXV cover only Class K.
What plating thickness is used?
3–5 µm bright tin over copper alloy 110, proven to survive 3 000-hour ASTM-B117 salt-spray; many imports stop at 1–2 µm.
Crimp tooling compatibility?
Color bands match B-series hex dies from Burndy, T&B, Greenlee, Huskie & Milwaukee dieless heads (U-style). No proprietary die needed.
Do you publish pull-out force data?
Yes — every size exceeds UL 486A Table 19 by >20 %. 4/0 AWG average pull = 1 980 lbf vs. spec 1 600 lbf.
Barrel design: standard vs. long?
Long-barrel LBC has 25 % extra crimp length for high-fault current gear. Burndy YA-L and Panduit LCA series offer similar, but at 15–20 % higher cost.
Temperature rating?
Listed for 105 °C continuous, matching Panduit & T&B; many economy lugs list 90 °C max.
Plating options for corrosive sites?
Standard tin, plus Electro-Tin-Nickel option for ESS battery racks and marine switchboards (>5 000-hr salt-spray life).
Are inspection windows available?
Yes — clear sight hole ensures full conductor insertion; inspectors can verify without cutting the lug.
Stud hole sizing?
1/4 in through 1/2 in in standard catalog; Gun-Drill service custom bores up to 5/8 in in 48 hrs.
Do you carry dual-rated Al/Cu compression lugs?
Yes — Bi-Metal BCU series friction-welded AL 1350 barrel to CU 110 palm, eliminating oxide inhibitor mess.
Color-coding system?
ICC/IEEE standard die-code stripes (pink = 4/0, brown = 3/0, green = 2/0, etc.) for mix-brand tool compatibility.
Do lugs ship with oxide inhibitor?
Copper lugs ship dry; aluminum dual-rated models pre-filled with oxide inhibitor and capped.
RoHS / REACH compliance?
All alloys & platings are RoHS 3 and REACH SVHC-free, documentation downloadable on the product page.
Grounding & bonding approvals?
UL 467 grounding & bonding listed up to 600 V — same as Burndy YA and T&B Color-Keyed.
Stock levels & cut-off times?
Inventory in Cheyenne, WY & Ontario, CA DCs. Orders in by 2 p.m. MST ship same-day.
Custom barrel laser-marking?
Free on 500+ pcs — engrave circuit ID, plant logo, or QC batch for traceability.
Do you offer installation tooling?
Yes — dieless 6-ton and 12-ton hydraulic heads plus color-coded hex die kits.
Short-circuit rating?
Withstands 65 kA RMS for 0.3 s on 500 kcmil per UL 486A appendix test.
Environmental packaging?
Lugs bagged in recyclable LDPE with QR-code datasheets — no PVC clamshells.
Warranty?
10-year workmanship & plating; failure rate <0.02 % field-reported since 2017.
Typical price vs. Burndy & T&B?
4/0 AWG long-barrel CT lug: $3.20; Burndy YA-L: $4.35; T&B 54107: $4.60 (June 2025).
Distributor pack sizes?
Cartons of 25 pcs ≤ 2 AWG, 10 pcs for 1/0 – 250 MCM, 5 pcs 300 – 750 kcmil, 1 pc 1000 MCM.
Bottom line — why pick Conversions Tech lugs?
Thicker tin, longer barrels, UL/CSA/TAA compliance, same-day U.S. shipping and a lower cost per termination than Burndy or Panduit — backed by a 10-year warranty.
