An enclosure system for isolating a conduit enclosure (202) for an explosion proof motor is provided. The enclosure system includes a stator enclosure defining a first enclosure opening. The enclosure system also includes a conduit enclosure (202) coupled to the stator enclosure. The conduit enclosure (202) comprises at least one side wall (206), a rear wall (208) coupled to the side wall (206), and an interior cavity (212). The rear wall (208) defines a first entry port (214) having a first volume. The enclosure system further includes at least one electrical lead. The at least one electrical lead extends through the first enclosure opening, through the first entry port (214), and into the interior cavity (212). The at least one electrical lead occupies a portion of the first volume and leaves a remaining volume. The enclosure system also includes sealing compound. The sealing compound is coupled with the first entry port (214) such that substantially all of the remaining volume is occupied.
