Abstract:
A transfer switch system for connecting loading circuits to a normal power source and to an emergency power source comprising:an enclosure having a front face and a plurality of side walls, wherein the front face defines a circular hole sized to fit an electrical power meter, and wherein the side walls define at least one hole for passing wires that carry electrical power from a normal power source and an emergency power source and at least one hole for passing wires that carry electrical power to loading circuits; an electrical power meter mounted within the enclosure and extending through the circular hole in the front face and electrically connected with the normal power source to measure the electrical power flowing from the normal power source; a normal power switch mounted within the enclosure and electrically connected to the normal power source and to the loading circuits and configured to connect the normal power source to the loading circuits in an on position and to disconnect the normal power source from the loading circuits in an off position; an emergency power switch mounted within the enclosure proximate the normal power switch and electrically connected to the emergency power source and the loading circuits and configured to connect the emergency power source to the loading circuits in an on position and to disconnect the emergency power source from the loading circuits in an off position; and a handle mounted on the front face of the enclosure proximate the normal power switch and the emergency power switch, wherein the handle includes a bracket extending into the interior of the enclosure to engage the normal power switch and the emergency power switch so that operation of the handle to a normal position places the normal power switch in the on position and the emergency power switch in the off position, and so that operation of the handle to the emergency position places the normal power switch in the off position and the emergency power switch in the on position.
