Completed Manual Transfer Switch, Interlock & Inlet in Matthews, NC

On December 3, 2024, our Charlotte branch completed a reliable backup power upgrade for homeowner Sam Hatcher in Matthews, NC. Lead technician Patrick Burke installed a manual transfer setup with a generator interlock and inlet, then added two dedicated 20A GFCI circuits to keep a dehumidifier and sump pump running during outages.

This project supports Whole-Home Generators planning by giving the customer a safe, straightforward way to power select circuits with a portable generator—without risking backfeed to the utility or damaging home equipment.

What We Installed

Manual transfer with interlock: We reconfigured the electrical panel so the new generator breaker and the selected backed-up circuits are positioned at the top-left of the panel. An interlock kit on the panel face prevents the main utility breaker and generator breaker from being on at the same time.
Generator inlet and feeder: From the panel, we installed up to 15 feet of feeder to a mounted generator inlet and provided a 15-foot whip to connect the customer’s portable generator when needed.
50A generator breaker: Installed to support the manual transfer solution and selected essential loads.
Two dedicated 20A GFCI circuits: New branch circuits for a sump pump and a dehumidifier to help protect the home from moisture and water intrusion during power interruptions.
Clear panel labeling: We labeled the panel with simple guidance so the homeowner knows exactly which breakers to operate during a future outage.
Electrical permitting: We filed the electrical permit with the county for this scope of work.

Note: This installation includes the interlock kit, 50A breaker, splicing in the panel as needed, up to 15 feet of feeder, a mounted generator inlet, and a 15-foot whip. It does not include conduit (if required) or a portable generator.

Why This Setup Works for Matthews Homes

Safety-first operation: The interlock ensures the generator cannot energize the utility lines, helping protect utility workers and your home’s electrical system.
Focused backup power: By dedicating circuits for the sump pump and dehumidifier, essential equipment can keep running, reducing the risk of water damage and managing humidity.
Straightforward use: During an outage, the homeowner simply connects the generator to the inlet with the whip and follows the labeled steps to energize the intended circuits.

We also installed new 12/2 NM-B wiring for the dedicated GFCI-protected circuits, giving the sump pump and dehumidifier their own reliable power path when running on generator power.

Permit and Compliance Notes

Touchstone Electric filed the electrical permit with the county for this project. Every jurisdiction has its own requirements; this permit covered only the electrical scope. If a project needs additional non-electrical permits (for example, historic preservation or zoning), those are handled separately.
