Safe, code-compliant manual and automatic transfer switch installations for portable and standby generators across Henning, TN.
Power dies. Generator runs. Nothing comes on inside the house.
That is the failure mode that surprises people. The generator outside is doing its job perfectly — engine running, voltage steady, fuel feeding cleanly. The reason nothing inside is working is that the bridge between the generator and the home was never built, or was built wrong, or has aged out.
The bridge is the transfer switch. Corea's Electrical Services builds the bridge the right way.
Perfect for portable generators. Weatherproof inlet, critical circuit wiring, clear breaker labeling, and safe operation training.
Service-entrance ATS for seamless standby generator operation. Full home backup with proper neutral bonding and coordination.
Priority load controllers that allow a smaller generator to support more of your home by intelligently shedding non-critical loads.
Repair or replacement of failed transfer switches, contactors, control boards, and integration with generators you already own.
We start with a detailed site visit and load study per NEC Article 220. We provide a clear written scope including equipment models, labor, permits, and timeline. Installation is followed by full commissioning, simulated outage testing, and final inspection.
