Abstract: Electric apparatus having distinct electric terminals has an input power terminal of electrically insulating material, including a base of electric insulating material having a first electric terminal base portion and a second electric base portion spaced from that first electric base portion, and a barrier wall of insulating material on that base acting as an isolator between the first and second electric terminals on these base portions, and preferably also as a standoff for a protective cover. A plurality of electric fuse holders in that or other electric apparatus may be mounted in mutually spaced relationship, and a heat sink including a frame around that plurality of mutually spaced electric fuse holders is in heat-transfer relationship with these electric fuse holders, and includes a cross-piece between each adjacent pair of the mutually spaced electric fuse holders.

Abstract: A circuit board holder has or is provided with a face plate and with walls projecting from an inside of that face plate. A pair of opposite ones of such walls are equipped with circuit board retainers. Such retainers may be inside and/or outside of a space in the circuit board holder. The circuit board holder is equipped with one or more holder retainers or resilient snaps for releasably retaining that circuit board holder in an aperture of a panel. Such holder retainers or resilient snaps may have serrations for engaging panels of different thicknesses at their apertures. Such panel may be provided with a slot or slots at that aperture for access to the holder retainer or resilient snaps through the panel. The holder retainer or resilient snap may be released through such slots, such as by screwdrivers or other release tool, for removal of the circuit board holder or similar device from the panel.
