Abstract
A safety device can provide electrical shock protection for an electrical appliance. Voltage sensors can monitor voltage levels among a power conductor, a neutral conductor, and a ground conductor. When sensed voltages indicate that these conductors are properly wired to an electrical power utility, inline switches can close to allow power to pass through the safety device to the appliance. When one or more of the sensed voltages indicates that the power level is too low to operate the appliance, one or more switches of the safety device can open to block power from passing through to the appliance. When one or more of the sensed voltages indicates that an electrical problem posing a shock hazard exists in the electrical appliance, one or more switches of the safety device can open to interrupt power from transmitting to the appliance.
