Sta-Kon M973 – Frequently Asked Questions
1) What wire sizes does the Sta-Kon M973 ring terminal take?
The M973 is sized for conductors from 4/0 AWG up to 250 kcmil. It is a single-size tubular lug, so smaller feeders like 2/0 or 3/0 will not crimp reliably in it, you would need a lug matched to that conductor.
2) Is the Sta-Kon M973 lug rated for 600 volt service equipment?
Yes, it carries a 600 V rating and is UL recognized under file E9809, which covers the usual panelboard, switchgear and motor connection work at that voltage class.
3) Can the Sta-Kon M973 be used on aluminum conductors?
No. It is a copper lug, so it is intended for copper conductors. Aluminum feeders in the 4/0 to 250 kcmil range need an AL9CU dual-rated or aluminum-bodied lug instead.
4) Is the M973 terminal insulated, and do I need to cover it after crimping?
It is a non-insulated lug, bare copper with no sleeve over the barrel. Once crimped you have to insulate the connection yourself, typically heat shrink or tape, wherever the installation requires the barrel to be covered.
5) Is a compression lug like the M973 the right choice over a mechanical set-screw lug?
A compression lug such as the M973 is crimped once with a die tool and cannot loosen or need re-torquing, which is why it is preferred for permanent feeder terminations and vibration-prone equipment. A mechanical set-screw lug is the choice when you have no crimp tool on site or expect to re-terminate the conductor later.
6) What is the Sta-Kon part number and origin for this 4/0 to 250 kcmil ring terminal?
Order it as Sta-Kon M973. It is manufactured in Mexico and finished bare metallic copper.
