Sta-Kon RC777M – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RC777M ring terminal crimp onto?
The RC777M is built for 12-10 AWG conductors. Yellow is the standard color code for that range on vinyl insulated terminals, so if your wire is 16-14 AWG you need a blue barrel instead, and 22-16 AWG takes red.
2) Is the Sta-Kon RC777M UL listed?
It is covered under UL file E9809. That is the detail an institutional or MRO inspector asks for when terminations have to be listed components in a panel.
3) Why choose a ring terminal instead of a spade (fork) terminal for a panel connection?
A ring tongue has to be slipped over the stud, so the screw comes fully out during install, but once torqued it cannot vibrate off the stud. A fork slides in under a loosened screw, which is faster on a crowded terminal strip. For vibration-prone work like the automotive and harness applications this terminal is intended for, the ring is the one to use.
4) Is the barrel on this Sta-Kon ring terminal copper or aluminum?
Copper. That means it is for copper conductors, not aluminum, where you would need an AL9CU rated connector and the appropriate inhibitor compound.
5) What does the M in RC777M mean on this Sta-Kon terminal?
The M designates the Mylar insulation sleeve over the vinyl insulated barrel. It gives the funnel entry extra abrasion resistance when you are pushing stranded 12-10 AWG wire into the barrel.
6) Is the Sta-Kon RC777M made in the USA for Buy American jobs?
Country of origin is the United States, which is what government and institutional procurement needs on record for domestic sourcing requirements.
7) Do I need a special crimp tool for the RC777M?
These are insulated barrel terminals and should be crimped with a tool matched to the 12-10 AWG yellow color code die. A generic plier style crimp on an insulated barrel is the usual cause of pull-out failures, so use the yellow nest on a ratcheting insulated terminal crimper.
