Electrical box assembly with an adjustable voltage divider

An electrical box comprising an adjustable voltage divider may include a housing comprising an inner surface and ribs or threads integrally formed on the inner surface of the rectangular housing. A voltage divider plate may be disposed within the housing with vertical edges of the voltage divider plate extending along and held in place between the ribs or threads integrally formed on the inner surface of the housing, the voltage divider plate dividing the housing into a high voltage area and a low voltage area. The voltage divider plate area may comprise a plurality of horizontal guide lines vertically offset from each other, and a plurality of vertical guide lines horizontally offset from each other and intersecting the plurality of horizontal score lines. Upper outer corners of the voltage divider plate may be inwardly disposed from the vertical edges of the voltage divider plate.
