A general purpose receptacle having selective single and split circuit electrical modes is adapted for mounting in a standard floor or wall mounting box. The receptacle is formed of a molded, one-piece receptacle body and a molded, one-piece receptacle front. Selection of single or split circuit operating modes is achievable by a break-off tab which normally electrically connects two sets of female contacts as a single circuit but which can be broken off so that the female contact sets are electrically separated. The receptacle is wired by placing the unstripped ends of insulated conductors at insulation severing terminals connected to the female contacts and forcing the conductors into the terminals. To accomplish this, a pair of suitably shaped side covers are hinged to the front part of the receptacle top to provide the requisite insulation-displacement forces. With the side covers secured in position, no terminals are exposed which might otherwise make electrical contact with metallic parts of the mounting box. Mounting, insulation severing and circuit mode selection can all be performed by using a screwdriver.
