A terminal reversing block mounts to a standard electrical disconnect device such as a circuit breaker or a pullout switch. The disconnect device has a housing which defines a cavity that faces in one direction for receiving a cable. Front and rear contacts are in the housing, one of which extends into the cavity for engagement with a cable. A terminal reversing block has a housing with at least one pocket which faces in a direction other than the opposite of the direction in which the disconnect device's cavity faces. A terminal collar disposed in the terminal reversing block pocket is engageable with a cable inserted into the pocket. A terminal in the reversing block has a mating portion and a connecting portion. The connecting portion engages the terminal collar. The mating portion engages one of the front and rear contacts of the electrical disconnect device. The arrangement of the directions in which the cavity and pocket face permits routing of the cables to minimize space requirements in a confined area, such as an enclosure or a cabinet.
