With this configuration any wire in the circuit may be hot at all times and there’s no protection against electrocution. When replacing an ungrounded device in an older circuit like this, use the polarized one above and not the grounded receptacle at the top unless it is grounded to a metal outlet box that is itself grounded to the house electrical system through a continuos metal conduit.
This receptacle can typically be found in living room and bedroom wall outlets. One of these may be controlled with a switch and/or wired to other receptacles in the circuit. For a 15 amp receptacle like this, 14/2 cable with ground should be used to feed the circuit.
This diagram shows the wiring to control a receptacle outlet with two 3 way switches. The source is at SW1 and 3-wire cable runs between all the devices. The hot wire from the source connects to the common terminal on SW1. The common on SW2 is connected to the hot terminal on the receptacle. The traveler wires are spliced in the receptacle box to run to the traveler terminals on each switch. The white cable wire is used as a traveler to SW2 and marked hot with black tape.
This arrangement makes it possible to power the heating elements in the appliance using the two 120 volts combined and one 120 volt wire to power timers and lights. This circuit is still used for clothes dryers but not for most new installations of kitchen ranges, for that a 50 amp circuit (pictured below) is now used.
