H3200-T type terminal cabinets are approved H3200 type enclosures in which substantially constructed terminal blocks are mounted. A variety of sizes for differing wire conditions are listed. The terminal blocks, rated at 30 amperes and 750 volts, are mounted on blind tapped buttons or pads that insure weather tightness and provide an air gap under the block. Each terminal block carries a white-faced target strip for marking connections.
