Sta-Kon L40-38 – Frequently Asked Questions
1) What wire size and stud size does the Sta-Kon L40-38 ring terminal take?
The L40-38 is sized for 4/0 AWG conductor, and the 38 in the model designation is the 3/8 inch stud hole. Order it when you are landing a 4/0 cable on a 3/8 inch bolt or stud. If your conductor is a different gauge, you need a different barrel size entirely, since the tubular barrel is crimped to the one conductor size.
2) Can I use a 4/0 Sta-Kon ring terminal on a 480 V panel feeder?
Yes. The L40-38 carries a 600 V rating, which covers 120/208, 277/480, and other common building distribution voltages up to 600 V. It is UL listed under file E9809.
3) Is the Sta-Kon L40-38 terminal copper or aluminum, and can I put it on aluminum cable?
The barrel is copper, so it is intended for copper conductors. For aluminum or copper-clad aluminum feeders you need a lug marked AL9CU or AL7CU with the correct inhibitor compound, not a copper-only terminal, because a copper barrel on bare aluminum sets up a dissimilar-metal joint that degrades.
4) Is the Sta-Kon L40-38 insulated, and does it need anything over the crimp?
It is a non-insulated terminal, so the copper barrel and the connection are bare once crimped. On anything where the lug could be contacted or shorted, you cover it after crimping with heat shrink or tape per your job spec. The upside of non-insulated is you can inspect the crimp and the conductor seating directly.
5) Does the Sta-Kon L40-38 come with the bolt and nut for the 3/8 inch stud?
No. It is the terminal only, a copper tubular-barrel ring lug. The 3/8 inch bolt, nut, and any washers come from the equipment you are landing on or are bought separately, and the crimp requires a hydraulic or heavy mechanical crimper with the correct 4/0 die.
6) What is the exact part number and country of origin for the Sta-Kon 4/0 ring terminal?
Order it as Sta-Kon L40-38. It is manufactured in Mexico. Finish is bare metallic copper, as expected on a non-insulated lug.
