Abstract: A conduit nipple grounding bushing to connect between two electrical enclosures or an electrical enclosure and a conduit body, comprising a body having a first portion and a second portion forming a hollow cylindrical interior for the passage of conductors therethrough, the body having a first opening at a first end of the body and a second opening at a second end of the body, the first portion having an outer surface with one or more mounting pads along a circumferential area, each of said one or more mounting pads configured for receipt of a grounding lug, and an end surface dimensioned to contact an electrical box about a knockout hole thereof, and wherein the second portion has exterior threads configured to pass through a knockout hole of an electrical box and dimensioned for receipt of a locknut if the conduit nipple grounding bushing is connected between two electrical boxes or for threaded engagement with a threaded hub of a conduit body if the conduit nipple grounding bushing is connected between an

Abstract: A connector assembly including a connector body with a spring clip including a first free end for engaging a side wall of an electrical box upon installation. During insertion of the connector body the first free end engages the knock-out hole perimeter and deforms so as to permit further insertion. An alignment rib also engages the perimeter to improve continuity between the connector assembly and the electrical box.

Abstract: An adjustable transition coupler for coupling AC/MC to conduit, having a body with a hollow cylindrical section and an extension member, the cylindrical section having a slot to allow passage of a stop plate. The coupler has an insulator (armor stop) with a hollow bushing at one end for insertion into a cavity of the cylindrical section and a stop plate extending radially outward, the stop plate movable by an adjustment screw between minimum and maximum deflections. The stop plate stops AC/MC from passage into the cylindrical section. The hollow bushing stops the conduit positioned in the hollow cylindrical section from passage into the extension member. The coupler has a strap to secure AC having different outer sheath diameters. Snap tabs on the insulator fit into holes in the body while a rib on the stop plate passes through a notch in the slot to facilitate installation and minimize movement.

Abstract: An adjustable transition coupler for coupling AC/MC to conduit, the coupler having a body with a hollow cylindrical section and an extension member with a curved section, the cylindrical section having a slot to allow passage of a stop plate. The coupler has an insulator with a hollow bushing at one end for insertion into a cavity of the cylindrical section and a stop plate extending radially outward, the stop plate movable by an adjustment screw between minimum and maximum deflections. The stop plate stops AC/MC from passage into the cylindrical section. The hollow bushing stops the conduit positioned in the hollow cylindrical section from passage into the extension member. The coupler has a strap with a curved section complementary with the curved section of the extension member so as to secure a range of AC having different outer sheath diameters.

Abstract: A split, locknut grounding bushing has a first metal bushing portion with first and second ends, a top, a bottom with teeth, an exterior surface with a boss for receipt of a lug, and an interior surface with threads; a second metal bushing portion similar to the first bushing portion, first and second insulators respectively connected to the top of the first and second metal bushing portions. The first and second metal bushing portions pivot with respect to each other at one end and can be fastened to each other at the second end. The threads of the first and second bushing portions can thread onto the threads of a conduit or connector passing through a hole in an electrical enclosure so as to engage the teeth on the bottom of the first and second bushing portions with an interior surface of the enclosure.

Abstract: A connector assembly including a connector body with a spring clip including a first free end for engaging a side wall of an electrical box upon installation. During insertion of the connector body the first free end engages the knock-out hole perimeter and deforms so as to permit further insertion. Once the connector body is fully inserted, the spring clip cooperates with a lug on the connector body to hold the connector assembly onto the electrical box.

Abstract: A split grounding bushing for placement on an end of an EMT or a rigid conduit has first and second metal bushing portions forming a ring, a grounding screw extending through the first or second metal bushing portion to make electrical contact with the EMT or rigid conduit, a lug secured to one of the bushing portions, the lug configured to secure a ground conductor thereto, a hinge formed at a second end of the first and second metal bushing portions, so that the first and second bushing portions can be opened or closed, and a removable metallic spacer having a shape that is a section of a cylinder and having an inner smooth surface corresponding to an outer surface of the EMT, the removable spacer also having an outer smooth surface corresponding to an inner surface of the second bushing portion.
