Ring Terminals

Ring Terminals

These are the ring terminals I use for terminating small wires to bus bars. GPS power / NMEA 0183 cables, VHF communication wires, NEMA 0183 etc. etc. all bundle very small 22-26GA wire in these harnesses.


I find it neat, clean, reliable & strong to use this method for terminating these wires. Often out the other side of the bus bar you'll be using larger GA wires anyway and mating a 22GA wire to a 16GA or 14GA often proves trouble prone.


An external speaker for a Standard Horizon VHF would be a good example of an item that would really really suffer if you kept that wire at its small "harness" gauge. Install rings, wire them to a busbar and out the other side of the busbar increase the wire gauge. Simple enough...


The middle connector is my favorite for this task and it's made by 3M. 3M rates/labels this as 24-26GA, but it will just barely fit a 22GA AWG wire perfectly. The model number of these terminals is MU24-6K. They also make an MU24-8K. The "6" & "8" signify the ring size the "24" the nominal wire size..


If you are using a terminal strip with #6 screws buy the MU24-6K, if using a bus bar with #8 screws use the MU24-8K. I buy these locally from HR Distributors in Portland, ME...
