    Switchgear
    Pad-mounted switchgears are used to provide switching points, and fuse protection for Ameren Missouri's underground facilities. As with pad-mounted transformers, switchgears are forest green in color. They are approximately four feet tall, and sit on a 6' x 6' pad. They are more common in commercial and industrial areas, but can be found in some residential areas.

    Junction Box
    A junction box is a simple piece of pad-mounted equipment, used for splitting high voltage circuits into multiple directions. As with pad-mounted transformers, junction boxes are forest green in color. Two sizes of junction boxes are used on the Ameren Missouri system. The smaller one is approximately 3' x 2' x 3' (H x W x L), and the larger one is approximately 3' x 2' x 6' (H x W x L).
