Sta-Kon G2-12 NON-INS - TUB RING TERM, 2, 1/2, ME

The G2-12 is sized for 2 AWG conductor. It is a non-insulated tubular ring terminal, so the barrel is bare copper with no sleeve, and it has to be crimped on 2 AWG wire to get the rated connection. Using it on a smaller gauge leaves the strands loose in the barrel.

Yes, 600 V is the stated rating, so it is usable in standard commercial and industrial power and control work at or below 600 volts. It also carries UL file E9809. Being non-insulated, it relies on the installer for insulation, so heat shrink or tape over the barrel is normal practice where the connection is not inside a listed enclosure.

No. The G2-12 barrel is copper, so it is a copper-only terminal. For aluminum or combination runs you need a lug specifically marked AL9CU or AL/CU, which this one is not.

Non-insulated, like the G2-12, is the usual choice at 2 AWG because heavy-gauge lugs are generally crimped bare and then covered with adhesive-lined heat shrink, which lets you inspect the crimp and pick the insulation color. An insulated barrel is more common on small control gauges where you want a one-step finished termination. The G2-12 ships bare copper with no sleeve.

It needs a heavy-duty crimper, not a hand pliers-style tool. At 2 AWG the tubular copper barrel calls for a hydraulic or large mechanical crimper with the matching die for that barrel size. A small insulated-terminal tool will not compress a 2 AWG barrel properly, and an under-crimped connection is the usual cause of heating at the stud.

It is a plain metallic copper lug with no color sleeve or coding, so it looks like any other bare crimp lug in a panel. Since the color is uncoded, identification has to come from your wire marking or heat shrink color rather than from the terminal itself.

Mexico. That matters on public and federally funded jobs where country of origin has to be documented in the submittal, so it is worth capturing on the paperwork up front.
