Abstract: An electrical power cord in one embodiment comprises a plug having prongs for insertion in an electrical outlet, a tubular member disposed about the plug, the plug and said tubular member being relatively movable. A spring is disposed between the tubular member and the plug and compressed when the prongs are inserted in the outlet so as to bias the plug in a direction away from the outlet. An interlocking lever is disposed on the tubular member for interlocking the tubular member and the plug when the prongs are inserted in the outlet. A wire coil is disposed on the tubular member and is provided with an electrical current when the prongs are inserted in the outlet to move a magnetically susceptible trip means in a manner to disengage the interlocking lever and allow the spring to eject the plug from the outlet.
