Compression Lug Applications Guide | Data Center, Solar, Wind, Hydro, Industrial, OEM
Where Conversions Tech compression lugs, mechanical lugs and grounding connectors are specified, by application, with the conductor and lug family for each. Every lug page on the site carries the UL listing, conductor range, barrel length, die index and the Burndy, ILSCO or Panduit cross reference.
Start with the conductor
Gauge is half the answer. Stranding class and conductor material decide the lug family: Class B and C building wire takes standard compression lugs; Class I and K fine strand (DLO, welding, battery) takes flex lugs; aluminum takes AL9CU dual rated or aluminum compression with compound.
- Cable type to lug cross reference: THHN, XHHW, DLO, welding, battery and aluminum
- DLO lugs vs standard compression lugs: what changes and when to use each
By application
| Application | Where lugs land | Guide |
|---|---|---|
| Data centers | Ground ring and MGB, switchgear and feeders, busway and PDUs, UPS batteries, generators, rack bonding | Data center lugs and grounding |
| Solar farms, utility PV and BESS | Combiners, inverter DC, AC collection (aluminum), substation grounding, battery containers | Solar and BESS lugs |
| Wind and hydro | Nacelle DLO leads, down tower cable, tower base switchgear, hydro generator leads, station DC, ground grids | Wind and hydro lugs |
| Industrial panels, switchgear builders and OEMs | Main lugs, internal wiring, ground and neutral bars, VFD leads, DC circuits, stocking programs | Panel shop and OEM lugs |
| Utility, substation and T&D | Substation grounding, pole line hardware, taps and splices | Utility and substation grounding |
| Telecom and cell sites | Grounding kits and bars, DC plants | Telecom and cell site grounding |
