Abstract

An assembly or adapter configured to provide a supply-side interconnect of electrical power to a distribution board. The adapter may be incorporated internal or external to the distribution board, by occupying the space of one or more circuit breakers, inserting an adapter into a meter termination socket, or the like. The adapter includes terminals provided to route the conductors from the utility to a breakout panel (or subpanel) for adding power devices as a supply side interconnect, and back to a regular route that may go through the meter and/or the main circuit breaker, and on to the loads. A switching component may provide an inline configuration that configures the conductors for backup function, and a parallel configuration that is a parallel interconnecting route when utility service is available.

First claim

The invention claimed is:

1. An assembly comprising, for a phase of an electrical distribution panel:
at least one utility-side electrical connector configured to be connected to a power meter conductor,
a circuit breaker comprising at least one load-side electrical connector configured to be connected to a load-side electrical conductor of an electrical distribution panel,
at least one first mechanical lug electrically connected to the at least one utility-side electrical connector,
a housing, and
at least one second mechanical lug electrically connected to the circuit breaker,
wherein the at least one first mechanical lug and the circuit breaker are electrically isolated.

2. The assembly of claim 1 , further comprising a front panel configured to provide a dead-front to the electrical distribution panel.

3. The assembly of claim 2 , wherein at least one of the at least one utility-side electrical connector, at least one load-side electrical connector, at least one first mechanical lug, and at least one second mechanical lug is located under the dead-front of the electrical distribution panel.

4. The assembly of claim 1 , further comprising a port configured to connect electrical wires to the at least one first mechanical lug or the at least one second mechanical lug.

5. The assembly of claim 1 , wherein the housing comprises a base that mechanically connects to a mechanical connector in the electrical distribution panel, and wherein the mechanical connector in the electrical distribution panel is configured to attach the assembly to the electrical distribution panel.

6. The assembly of claim 5 , wherein the at least one utility-side electrical connector and the at least one load-side electrical connector are disposed within the housing.

7. The assembly of claim 1 , wherein the housing is mechanically connected to the electrical distribution panel.

8. The assembly of claim 1 , wherein the at least one utility-side electrical connector is configured to electrically connect to a power meter.

9. The assembly of claim 1 , wherein the at least one load-side electrical connector is configured to electrically connect to a load.

10. The assembly of claim 1 , further comprising at least one from the group consisting of a switch, a sensor, a relay, an electrical meter, an inverter, a micro-inverter, a communication device, a shunt trip device, an audible alarm, an arc-fault protection device, and a ground-fault protection device.

11. The assembly of claim 1 , wherein at least one of the at least one utility-side electrical connector, at least one load-side electrical connector, at least one first mechanical lug, and at least one second mechanical lug is configured to be electrically connected to at least one selected from the group consisting of an alternative energy source, a battery backup, a solar power generation system, a wind power generation system, a backup electricity generator, a geothermal power generation system, a biofuel power generation system, and a hydroelectricity power generation system.

12. The assembly of claim 1 , wherein the circuit breaker comprises at least one from the group consisting of a thermal magnetic circuit breaker, a ground-fault circuit-interrupter breaker, a residual-current circuit breaker, and an arc-fault circuit-interrupter breaker.
