| 1. A dimmer for controlling power to a load, the dimmer comprising:
a phase input terminal configured to couple to an AC power source;
a ground terminal configured to couple to a ground connection of the AC power source;
a load output terminal configured to couple to the load;
a switching circuit electrically coupled between the phase input terminal and the load output terminal;
a controller configured to control the switching circuit such that power to the load is selectively controlled; and
a ground leakage power supply, wherein the ground leakage power supply is a switched mode power supply electrically coupled
to the phase input and ground terminals, wherein the ground leakage power supply derives power only from the phase input and
ground terminals;
wherein the controller receives power from the ground leakage power supply.
