## Abstract

System, apparatus, and methodology for the provisioning of power to electrical loads and an EV charging station in a multi-dwelling building environment. Two electrically parallel configured circuit breakers, one to the tenant residence and one to an EV charging station, are connected to two load straps connected to a meter socket. The load straps are configured to supply simultaneous power to both the appliances of a tenant residence and an EV charging station.

## Claims

### Claim 1

A system for power distribution, the system comprising:
a metering device for measuring power consumption;
a meter socket connected to the metering device;
a first U-shaped load strap connected to the meter socket;
a second U-shaped load strap connected to the meter socket;
a tenant circuit breaker for an individual unit of a multi-family residence, the tenant circuit breaker connected to the first U-shaped load strap and the second U-shaped load strap; and
an EV circuit breaker for an EV charging station located in a parking spot for the multi-family residence, the EV circuit breaker connected to the first U-shaped load strap and the second U-shaped load strap;
wherein the tenant circuit breaker and the EV circuit breaker are electrically connected in parallel to each of the first U-shaped load strap and the second U-shaped load strap,
wherein the first U-shaped load strap comprises a first conductor portion connected to a first bus, and the second U-shaped load strap comprises a second conductor portion connected to a second bus,
wherein the first bus is connected to a pair of first stabs, and the second bus is connected to a pair of second stabs,
wherein the first bus and the pair of first stabs form a U-shaped portion of the first U-shaped load strap, and the second bus and the pair of second stabs form a U-shaped portion of the second U-shaped load strap, and
wherein the first U-shaped load strap and the second U-shaped load strap are in contact and are positioned along a substantially common longitudinal axis.

### Claim 2 (depends on 1)

The system for power distribution of claim 1, wherein one of the first stabs and one of the second stabs are each connected to both the tenant circuit breaker and the EV circuit breaker.

### Claim 3 (depends on 2)

The system for power distribution of claim 2, wherein the tenant circuit breaker and the EV circuit breaker are arranged substantially vertically stacked side by side with respect to one another.

### Claim 4 (depends on 3)

The system of claim 3, wherein the tenant circuit breaker and the EV circuit breaker are double pole circuit breakers.

### Claim 5 (depends on 4)

The system of claim 4, wherein one U-shaped load strap of the first U-shaped load strap and the second U-shaped load strap includes an insulating sheath configured to electrically insulate the one U-shaped load strap from another of the first U-shaped load strap and the second U-shaped load strap.
