A grounding fitting for mounted engagement with an electrical enclosure has an elongated body with a first generally cylindrically shaped section and a hub section. Both sections have a longitudinally extending passageway dimensioned for passage of a ground electrode/ground rod. The first section includes a threaded aperture for receipt of a screw to electrically and mechanically secure a ground electrode/ground rod to the grounding fitting. The hub section is also dimensioned to secure a rigid or EMT conduit thereto. The first section includes a flange at one end with associated threads formed in the outer surface of the first section to mechanically and electrically secure the grounding fitting to an electrical enclosure with a locking ring. An O-ring positioned in the flange provides a fluid resistant barrier relative to the interior of the electrical enclosure.
A concrete exclusion structure is formed by a housing having a shell, end walls, and one or more score lines of reduced wall thickness. The housing defines an interior void that is dimensioned to enclose a coupler assembly. Knockouts in the end walls or knockout cones allow passage of tubes associated with the coupler assembly. The exclusion structure prevents uncured concrete from contacting the coupler assembly. The structure can fracture after the concrete has cured thereby allowing portions of the coupler assembly to move relative to each other. Such fracture is typically about one of the score lines.

A second threaded aperture in the cylindrical housing in cooperates with the second channel to secure a grounding rod and, if present, the associated grounding conductor wire. The grounding bridge may include a cover to form an intersystem grounding bridge system.
A connector assembly having an external retainer ring for both securing a connector body to an outlet box and also securing a conduit or cable from movement relative to the connector assembly. A multi-function retainer ring having a plurality of finger-like extensions or tabs with at least a portion of the extensions being inwardly bent. The inwardly bent tabs engage and retain a captured wire or conduit upon assembly. Other tabs function to engage an inner wall of a knock-out hole of an outlet box upon insertion of the connector assembly into the outlet box. A method of connecting a wire to a junction box using the connector assembly is also disclosed.
An adjustable ground clamp for easy positioning onto electric conduits of different diameters and grounding multiple electrical devices. A first and a second jaw are pivotally connected and have differently angled jaw surfaces. A distal end of the first jaw has an elongated hole and a distal end of the second jaw has a curved fork having a slot for receiving a bolt with a cylindrical nut. A fastener connects a ground conductor or wire to the ground clamp. A terminal block accepts ground conductors from multiple different electrical devices. The jaws may be easily separated for placement of an electrical conduit without separating or detaching any parts from the ground clamp, making attachment to an electrical conduit quick, easy, and secure. The terminal block permits different electrical devices to be grounded with a single ground clamp.
A sealing reducing washer is formed from a metallic reducing washer having a front surface, a rear surface, an outer periphery, and an inner periphery with a pliable rim secured over the outer periphery of the metallic reducing washer, a portion of the rim circumferentially depending below the rear surface of the metallic reducing washer adjacent the outer periphery of the metallic reducing washer so as to form a weathertight seal against a surface of an electrical enclosure when the sealing reducing washer is secured to the enclosure, and a pliable toroid circumferentially positioned adjacent the inner periphery of the metallic reducing washer and extending circumferentially above the front surface of the metallic reducing washer in the region adjacent the inner periphery of the metallic reducing washer, the toroid dimensioned to form a weathertight seal with an electrical conduit or raceway.

Removable push electrical fitting for electrical metallic tubing or EMT having improved pullout resistance
An electrical fitting having a gripping device with a plurality of gripping tabs forming a helix or spiral. The gripping tabs have a twist creating increased pullout resistance and easier disassembly. The electrical fitting permits electrical metallic tubing or EMT to be quickly attached to and removed from the electrical fitting without disassembling the fitting or cutting the tubing. A body with a locking end having a plurality of griping tabs receives an end of the tubing pushed into the fitting. The gripping tabs securely hold the tubing preventing loosening or removal. The helix or spiral and twist formation of the griping tabs permits easy removal of the tubing by rotating the tubing counter-clockwise.

By providing a grounding conductor assembly affixed to a conduit bushing in a manner which enables the grounding conductor assembly to extend inwardly from the bushing, effectively being positioned coaxially with the inside diameter of the rigid metal conduit, conduit bushing is realized which enables all grounding wires to be quickly and easily mounted to the grounding conductor assembly. The conduit bushing of the present invention includes a generally circular shaped cover or cap member mounted to the terminating end of the conduit and incorporating an enlarged aperture which overlies the elongated passageway formed in the conduit. In this way, the electrical power carrying wires are able to extend outwardly from the rigid metal conduit into the desired outlet box, junction box with the grounding wire being quickly affixed to the receiving zone of the grounding connector assembly.
A clip having a U-shaped body and a cantilevered replacement tab with a threaded hole. The clip replaces damaged threaded tabs on a metal electrical box. The U-shaped body of the clip is slid over the wall of an electrical box after the damaged threaded tab is removed. A cantilevered replacement tab extends from the U-shaped body of the clip having a replacement threaded hole therein for receiving a machine screw. The machine screw holds an electrical outlet within the electrical box. The cantilevered replacement tab creates a moment arm causing an attached tooth to bite into a surface of the electrical box. The clip is thereby securely held within the electrical box and is prevented from sliding off of the box as the electrical outlet is drawn into the box by the machine screw. The present invention provides an improved clip for the replacement of a tab in a damaged electrical box and eliminates the need for replacing the electrical box.
An electrical fitting in the form of a connector or coupler for connecting an electrical metallic tube or EMT to an electrical box or panel or to one another. A unidirectional locking device is disposed in an outermost chamber and an O-ring is disposed in an intermediate chamber. The unidirectional locking device has gripping tangs. The intermediate chamber and gripping tangs are sized so as to prevent the gripping tangs from contacting the O-ring. A contact shoulder is used on one end of the fitting to prevent excessive compression of a sealing washer. Internal longitudinal radially increasing ribs are formed in the fitting body improving continuity and support for the EMT. A tube support may also be provided to prohibit any undesirable bending movement of the EMT connected thereto.
