OK, I just pulled the old beast out of the nether-regions of my desk.
It's a General Electric, I-30-A for 240 volts, 15 amps, three wires, 60 hertz. A-Base. (Why did I think it was a Westinghouse?
)
I put a meter across the four terminals and got continuity when I put the probes across the two outer terminals and then the two inner ones.
In other words:
1 2 3 4
X | X X | X
(KEY: X = terminal screw, | = plastic barrier. The numbers are my own)
I placed the continuity meter probes on terminals 1 and 4 and got continuity. Across terminal 2 and 3 the same thing.
There are also these two copper bridging straps set up above the terminal screws -- with scrwews that allow you to change the way these things are bridged.
Hmmmm.....
