1. An electrical safety device, for connection between a high voltage electrical power source and a load, comprising:

  • an outlet comprising a positive voltage terminal and a negative voltage terminal;

    means for receiving a high voltage input from a high voltage electrical source;

    means for providing low voltage to the outlet from the source high voltage input, the low voltage being less than the source high voltage input;

    means for monitoring current flow across the outlet positive voltage terminal and the negative voltage terminal and providing an electrical output when such flow occurs, the current flow indicative of whether a load is connected to the outlet;

    a first means for switching from a first state to a second state when current flows across the outlet positive and negative terminals and providing an electrical output in the second state; and

    a second means for switching comprising a plurality of sets of contacts, the second switching means configured to change the plurality of contacts from a first state to a second state upon receiving an electrical input from the first switching means, and configured to provide a connection from the high voltage source to the outlet in the second state.
