Patent ID: 8248745

Claim:
A method of providing electrical over/under voltage protection comprising: a. providing a connecting means for connecting to a supply of at least one phase of alternating current power having a line, neutral and ground; b. providing a sensing means for sensing the voltage of the supplied power, wherein the sensing means detects voltage differences between the following lines: i. line and neutral; ii. line and ground; or iii. neutral and ground; c. determining whether the voltage is within an acceptable voltage range across at least 2 of the preceding lines; d. providing a power surge absorption means; e. providing a distribution means having a corresponding line, neutral and ground for distributing the sensed power; f. providing a disconnecting means for disconnecting the distribution means line and neutral from the power source when the sensing means detects an out-of-tolerance voltage condition across the line-neutral, or line-ground, wherein the sensing means activates the disconnecting means before the apparatus suffers electrical damage; g. a reconnecting means for reconnecting the sensed power to the distribution means when the sensing means no longer detects an out-of-tolerance voltage condition; and h. wherein detection of the out-of-tolerance voltage condition comprises detection of a voltage of less than approximately 60 Vrms and greater than approximately 132 Vrms.
