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.

Our Process — Sequence Matters

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.

Why the Transfer Switch Usually Fails Before the Generator Does

Transfer switches endure constant electrical stress. We recommend annual exercising under load and replacing surge protection ahead of the ATS. Proper maintenance dramatically extends service life.

Frequently Asked Questions

Does the install need a permit?

Yes. Every transfer switch installation in Bellbrook requires an electrical permit and final inspection. We handle everything.

How long from approval to power-up?

Most whole-house automatic installations complete in one to two working days on-site, with permitting adding 1–3 weeks total.

Can you tie into a generator I already own?

Yes. We routinely retrofit portable generators, existing standby units, and units purchased elsewhere.

What size generator do I need?

We perform a load calculation during the site visit and present options for whole-house or critical-load systems.
