ABSTRACT:
A wire entrance fitting for eliminating leakage through a side wall of a tank has a tubular member which is externally threaded at opposed ends. Plural, threaded members are received in the tubular member and extend through an encapsulating, generally inert material. A first end of the threaded members receives an exposed wire from a cathodic protection system positioned in the tank for inhibiting corrosion, is crimped thereto, and sealingly encapsulated by a resinous material. A second end of the threaded members extends outwardly from the tank for connection to an external power supply. A flange is disposed along the tubular member and extends outwardly therefrom. The flange facilitates receipt of a junction box in one arrangement and positions an elastomeric seal member along an inner face of the tank side wall in a second arrangement.
