Abstract
A plug-in type pothead includes specially designed seal sleeves formed from a heat shrinkable polymer. One end of the sleeve has an annular collar about it which, when snugly fitted within the motor lead entry hole of the terminal block, forms a watertight seal between the terminal block and the sleeve. The other end of each of the sleeves is heat shrunk about its respective motor lead to form a watertight seal between the sleeve and the lead. In addition, a gasket between the connecting face of the terminal block and the connecting face of the pothead provides a watertight seal between the pothead and the terminal block. The result is a completely watertight connecting system, extending from the pothead through the terminal block to the motor leads.
