Sta-Kon M974 – Frequently Asked Questions
1) What wire size does the Sta-Kon M974 ring terminal accept?
The M974 is sized for 4/0 AWG through 250 kcmil conductors. It is a non-insulated tubular ring terminal, so the barrel takes the full stranded conductor and is crimped with a compression tool matched to that range. Anything smaller than 4/0 will not fill the barrel and should not be crimped in it.
2) Can I use the M974 copper lug on aluminum conductors?
No. The M974 is a copper terminal and should be used on copper conductors only. Aluminum feeders in the 4/0 to 250 kcmil range need an aluminum or AL9CU dual-rated compression lug instead.
3) Is the Sta-Kon M974 rated for 600 volt circuits?
Yes, the M974 carries a 600 V rating, which covers standard commercial and industrial feeder and branch circuit work up to 600 volts. It is UL recognized under file E9809.
4) Does the M974 terminal come with insulation or do I need to sleeve it?
It is a non-insulated terminal, bare copper with a metallic finish. If the installation needs the barrel covered, you add heat shrink or a boot yourself. For panel and bus connections inside an enclosure the bare barrel is normally left as-is.
5) What is the exact part number and manufacturer for ordering this 4/0 to 250 kcmil ring lug?
Order it as Sta-Kon M974. It is a single-model item, no finish or size options to choose, and it is manufactured in Mexico.
