Notes
Fine strand flexible wire has a slightly larger conductor diameter than code stranded wire. When using Code Lugs with 2 AWG and larger Arctic Ultraflex Blue® and similar fine strand flexible wire, step up one lug size.
Flex Lugs, sized for the larger conductor diameter of fine strand flexible wire, are available on pages 100-101

Notes
Rated 35KV Applications — Copper Conductors Only
Heavy Duty Single Hole and Double Hole Flex Compression Lugs are designed for use with both code stranded and flexible fine stranded copper conductor wire such as Class K Arctic Ultraflex Blue.® Flex Lugs can be used with class G, H, I, K, and M flexible conductors and Diesel Locomotive (DLO) wire.
Flex Lugs are sized for the larger conductor diameter of flexible wire. When using flex lugs with either flexible or code stranded conductors, match the lug to the wire size.

If you need something that is not here, ask us: 8am to 5pm AKST, Monday to Friday.
What size lug do I need for my cable?
Conductor size and stud size. Compression lugs and splices are stocked to 1000 MCM, UL Listed and CSA Certified to 90°C, studs from #10 to 5/8 inch. Two-hole lugs are specified by hole spacing on centers. Code lugs fit code strand. Flex lugs fit fine strand. Polar Wire wire is Class K and needs a flex lug.
Do you stock split bolts?
Yes. Copper split bolts are on the online store. Class K wants a compression splice.
Do I have to buy the lugs, or can you crimp them on?
Parts are sold on the online store. A finished cable with the terminations already crimped is a custom assembly.
