摘要： 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.

摘要： A ladder accessory is easily adapted for mounting on ladders of different shapes and sizes. The ladder accessory includes mounting slots whose long dimensions run in at least two different directions. This allows mounting hardware to be placed anywhere along the length of the slot, as may be convenient for a particular ladder's geometry.
