Generator Interlock Kit Installation in Little Rock, AR

For many Little Rock homeowners, a portable generator wired through an outdoor inlet and a breaker interlock is enough to get through a storm outage, running the refrigerator, lights, a gas furnace blower or window AC unit and the internet. The interlock prevents back-feeding Entergy Arkansas lines, protecting crews during restoration.

Older homes may have knob-and-tube, ungrounded circuits and small services, and many have been renovated several times. Mature trees over overhead lines make storm damage to service drops common.

What generator interlock kit installation involves

Plugging a generator into a wall outlet, or a "suicide cord", can send power back onto utility lines and injure line workers. An interlock and inlet box is the lower-cost, code-compliant alternative to a full transfer switch.

With an interlock, you choose which circuits to run during an outage, such as the furnace blower, refrigerator, sump pump and some lights, within the generator's capacity.
