Abstract: An enclosure, such as an electrical enclosure, includes a base having a series of walls that define an interior, and a cover. The base and cover include a hinge arrangement that enables the cover to be secured to the base for movement between a closed position and an open position. The hinge arrangement enables the cover to be hinged to either a first wall of the base or an opposite, second wall of the base. A latch member is configured to be selectively engaged with either the first wall of the base or the second wall of the base, and is engaged with the second wall of the base when the cover is hinged to the first wall of the base and is engaged with the first wall of the base when the cover is hinged to the second wall of the base.

Abstract: The present inventors have recognized that locating cable adapters which may be required in electrical systems, such as between power generators and electrical inlets, may be greatly aided by applying visually striking distinguishing indicators, such as colors, molded-in patterns or shaped identifiers, shaped protrusions, and the like, at ends of each cable adapter which distinguishing indicators correspond to electrical/mechanical standards or connections of various types. This, in turn, may allow for rapid deployment of such cable adapters in the system, including from a kit.

Abstract: A load management module for disconnecting continuous loads for a predetermined amount of time when an excessive load is experienced to permit critical intermittent loads to remain energized. The load management module has a first group of relays and a second group of relays each connected to various intermittent loads (e.g., lighting branch circuits) and each controlled by a timer. The load management module activates the relays when a maximum power output of a secondary power source is exceeded. An automatic transfer switch capable of operating with larger disconnect/breaker sizes (e.g., 200 amps) for larger emergency backup systems. The automatic transfer switch comprises a plate operably connected to a drive system and a pair of breakers.

Abstract: A switching device includes multiple switches configured to selectively connect one of two power sources to electrical loads. The switching device may include either single-pole or double-pole, double-throw switches and corresponding single or double circuit breakers. The single and double circuit breakers are each configured to be inserted into openings having the same physical dimensions. At least one of the switches is a double-pole, double-throw switch, allowing two branch circuits to be transferred between power sources via the switch. A double breaker corresponding to the double-pole, double-throw transfer switch permits each of the branch circuits being switched by the double-throw switch to be wired through a separate protective circuit.

Abstract: A timer assembly housing is configured to include a number of features, including but not limited to a tortuous sealing lip, adjustable hinge assembly, removable backing plate, removable pin hinge, toggle switch, and a wiring lid. The timer assembly includes a weatherproof housing having a base with a series of sidewalls and a rear wall, the base sidewalls extending forward from the rear wall to an open front, a lid having a series of sidewalls and a front wall, the lid sidewalls extending forward from the front wall, and a timer assembly positioned within the base. The lid is selectively pivotably secured to the base along one of the base sidewalls.

Abstract: An automatic transfer switch configured for connection to a non-traditional, full-time or intermittent power source, such as a wind turbine or solar panel, selectively connects the non-traditional power source as a primary power source and a utility-derived power source as a secondary power source. The intermittent power source includes an energy storage device, such as a bank of DC batteries, to supplement power delivery during periods of low energy production. The power is provided to an AC load via a DC-to-AC inverter. The transfer switch includes an input to monitor the voltage level on the energy storage device and will switch from the primary power source to the utility power source when the voltage level on the energy storage device drops below a preset level. Thus, a loading condition that exceeds the rating of the inverter will not fault the inverter or limit the power available to the loads.

Abstract: A transfer switch configured to transfer connection of each power conductor and neutral conductor of a load between two power supplies. The transfer switch includes a switch member configured to transfer each of the connections in tandem. The transfer switch disconnects each power conductor prior to disconnecting the neutral conductor of the first supply when disconnecting the load from either power supply and connects the neutral connector prior to connecting each power conductor when connecting the load to either power supply.

Abstract: A method and system for selectively controlling the supply of electrical power to an electrical panel that is capable of receiving electrical power from more than one power source, such as a utility power supply and an auxiliary power supply, e.g., an electrical generator, prevents the neutral conductor of the electrical panel from being connected to one power supply when the hot conductors of the electrical panel are connected to another power supply.

Abstract: An interlock arrangement is configured for controlling a pair of aligned switches connected to two alternate power supplies. An interlock member is positioned between the aligned switches and is moveable between a first interlock position and a second interlock position. The interlock member has first and second blocking components. In the first interlock position, the first switch is ON and the second blocking component prevents movement of the second switch to an ON position, and the interference between the first switch and first blocking component prevents the interlock member from moving to the second interlock position. In the second interlock position, the second switch is ON and the first blocking component prevents movement of the first switch to an ON position, and the interference between the second switch and second blocking component prevents the interlock member from moving to the first interlock position.

Abstract: An electrical box cover including a body for securing a plurality of electrical connections therein, a cover having a door, the door having a first end with at least one male hinge, at least one female hinge attached to the cover, and wherein the at least one male hinge is removably connected with the at least one female hinge to selectively open and close the door.

Abstract: A timer assembly is configured with a motor with slim construction so as to provide a thinner and more compact timer assembly. A timer assembly with a thinner profile and reduced thickness is achieved by incorporating the motor within the timer's baseplate. Additional advantages may be achieved by positioning the motor within an area defined by the baseplate and the time indicator, or by mounting the motor in an offset manner with respect to the baseplate. Further, the orientation of the motor may be changed to mount the motor to the front or rear of the baseplate to provide for an additional thickness reduction.

Abstract: A timer is configured with an electrical contact assembly with a thin construction, which provides a thinner and more compact timer assembly. In particular a thinner and more compact timer assembly is achieved by implementing various features of the present invention, including but not limited to, recessed contact arm channels, contact arms positioned wholly on a single side, contact arms oriented with a length parallel to the baseplate and a thickness parallel with the baseplate thickness, and a slim profile actuator which moves in the direction of the length.

Abstract: An electrical power distribution apparatus that is configured to selectively communicate power from alternate power sources to one or more loads in a manner that maintains isolation of the input power derived from the alternate sources. The electrical power distribution apparatus includes a neutral input for connecting to a neutral output of the auxiliary power supply and a ground conductor for connecting a ground conductor of the auxiliary power supply. The apparatus includes an electrical bus that receives electrical power from a first electrical output of the auxiliary power supply and unswitchably communicates the first electrical output to a breaker connected to a load.

Abstract: A line-side circuit interrupter protection system monitors the current flowing in a circuit in order to determine whether any current is flowing outside of the circuit upstream of the point at which a power supply is connected to a plurality of circuits. The system is located between the power supply and the main circuit panel, which is advantageous in certain applications in which an auxiliary power supply is used when a utility power supply is unavailable. In the event that the system detects current flowing outside of the circuit, the circuit will be broken to eliminate any potentially unsafe conditions.

Abstract: A switch coupling assembly is configured for coupling switch handles to provide simultaneous actuation and deactivation of an electrical device. The switch handles are arranged in a side by side configuration and have passages are aligned. A coupling rod is inserted through the passages in the handles. A spacer is positioned between the switch handles and receives the coupling rod therethrough. An outside surface of the coupling rod is threaded to interact with either or both of the inner surface of the spacer or the inner surface of the handles in order to prevent inadvertent axial motion of the rod relative to the spacer or the switch handles.

Abstract: A power inlet box suitable for outdoor or external use is configured in such a manner so as to prevent moisture from entering the power inlet enclosure. A hinged lid assembly is installable directly on the top face of a flanged power inlet enclosure to provide a face seal therewith. The hinged lid assembly has a cover and a base that form a tongue-and-groove seal, thus providing a first line of defense from moisture or other contaminants entering the inlet. As a second line of defense, a tapered stopper is provided on the inside of the cover to provide a stopper seal. A lateral seal is provided at the hinge point of the hinged lid assembly to prevent moisture from entering the hinge area where a tongue-and-groove seal is not present.
