Abstract
An energized parts guard is disclosed comprising a panel of substantially rigid, electrically insulative material wherein the substantially rigid panel further comprises a first one or more apertures and a second one or more apertures. The first one or more apertures are so dimensioned to accept one or more circuit breakers inserted into the first one or more apertures such that there is less than a 12.5 mm gap between the panel and the circuit breaker on at least two sides of the one or more circuit breakers. The second one or more apertures are positioned to facilitate access to at least one terminal of each of the one or more circuit breakers when the one or more circuit breakers are inserted into the first one or more apertures.

A power circuit-breaker enclosure comprising:
- a housing;
- one or more circuit breakers electrically connected to an electrical bus;
- an insulating guard, said insulating guard comprising a sheet of substantially rigid, electrically insulative material wherein the substantially rigid sheet further comprises a first one or more apertures and a second one or more apertures;
- wherein the one or more circuit breakers are positioned in the first one or more apertures and the first one or more apertures are further dimensioned to prevent accidental contact with any exposed electrical part within the enclosure on at least two sides of the one or more circuit breakers;
- and
- wherein the second one or more apertures are positioned to facilitate access to at least one terminal of the one or more circuit breakers and to prevent accidental contact with any exposed electrical part within the enclosure.
A method of preventing unintended shock or exposure to electrical discharge comprising:
- installing an insulating guard in an electrical panel to prevent contacting exposed energized electrical elements in the electrical panel during electrical maintenance of the electrical panel,
- wherein the insulating guard is electrically isolating and includes one or more openings dimensioned to prevent accidental contact with the exposed energized electrical elements in the electrical panel.
