    Hey all, I am looking to see if any one know the origin of RNS (R and S maybe, not entirely sure) circuit connections are. or if we are calling them the wrong thing. I don't have picture yet, but basically it is a round brass fitting about and inch and a half in diameter with three pins in a triangle inside that plugs into a box with the female equivalent and is held in place by a screwing brass collar ring.
