This wooden cutout box I found just down the street at a Yard Sale. Here are the specs for it. The brass identification tag says: Expulsion Type Primary Cutout, Cat 268773, Type E, Form B, Amp 100, Volts 7500, Rupture C Capacity GA, General Electric Co. Schenectady, N.Y. U.S.A. The mounting brackets have the number 1595610G stamped on them. It measures: roof 7" x 9", Height 14", Width 5 ½", Length 7", and has a 2" opening on the bottom with a ceramic piece. Only damage is one cover rusted through. A complete unit with all its insides. I will probably keep it now, and restore it then sell it later.
