An apparatus and method for protecting against electrocution hazards that arise when an appliance is electrically connected to a miswired single-phase AC electrical source are described. Protection is provided against miswiring conditions that causes the putative ground line of the electrical source to be either electrically energized or to be electrically open. The apparatus includes one or more sensors that detect if the electrical source is miswired and operate one or more switches which preclude electrical continuity to one or more of the electrical lines of the applianc e if a miswiring is detected. The method includes the steps of detecting if the putative ground of the electrical source is electrically energized, and if it is, then precluding electrical continuity between the putative ground of the electrical source and the ground of the appliance.
