Abstract
A power adaptor is provided including a housing receiving a first power cord couplable to a power source through a and a second power cord couplable to a load through a second axial end, a protective capacitor mounted on a circuit board within the housing, a first set of terminals mounted on a first side of the circuit board adjacent the protective capacitor and configured to electrically couple line and neutral wires of the first power cord to the protective capacitor, and a second set of terminals mounted on a second side of the circuit board adjacent the protective capacitor and configured to electrically couple line and neutral wires of the second power cord to the protective capacitor. The protective capacitor is configured to discharge when current draw by the load exceeds a current threshold.
