SAFETY APPARATUS HAVING TERMINAL SHIELD WITH INDICATION CIRCUIT, AND CIRCUIT INTERRUPTION APPARATUS
A safety apparatus is a terminal shield having an indication circuit incorporated therein. The safety apparatus is usable with a circuit interrupter to overlie one or more terminals of the circuit interrupter that are connected with line and load conductors and to thereby form a circuit interrupter apparatus. The safety apparatus can be employed at the line side of a circuit interrupter, at the load side of a circuit interrupter, or at both sides of a circuit interrupter. The safety apparatus can be provided as part of a new circuit interrupter apparatus or can be provided to retrofit existing circuit interrupters. The indication circuit advantageously outputs from a top surface of the terminal shield one of a visual indication and an audible indication when one or more terminals of the circuit interrupter are electrified, thereby easily conveying to a technician the portions of the circuit interrupter that are electrified.
Four-way automatic transfer switch power topology
Systems and apparatuses include a mesh network for power distribution. The mesh network includes a plurality of interconnected four-way automatic transfer switches. Each four-way automatic transfer switch includes a common pole, a first pole selectively coupled to the common pole with a first switching device, a second pole selectively coupled to the common pole with a second switching device, a third pole selectively coupled to the common pole with a third switching device, and a fourth pole selectively coupled to the common pole with a fourth switching device. The common pole of a first interconnected four-way automatic transfer switch of the plurality of interconnected four-way automatic transfer switches is structured to provide power to a corresponding load, and the common poles of two or more of the plurality of interconnected four-way automatic transfer switches are structured to receive power from corresponding power sources.
