WARNING THIS IS NOT A 2 WIRE TYPE BUT A 3 WIRE TYPE! When Cooper Tools bought Eaton Electric they didn't bother converting the OLD EATON NUMBER to a 2 wire version. AND PUT THE SAME NUMBER ON THE 3 WIRE VERSION OF COOPER TOOLS. So it doesn't match the picture of the Revain with the 2-wire block. Now they ship a new 3 wire device and keep making this ERROR. BEWARE! THE CORRECT NUMBER FOR THE 2-WIRE DEVICE IS PART MODEL NUMBER: C1746V translated by Revain as "COOPER WIRING” 6 OUTPUT POLARIZED TANK
