Abstract
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.
