Touchstone Electric’s Greenville team completed a turnkey generator readiness upgrade for homeowner Elizabeth Orama in Ninety Six, SC. On August 29, 2025, technicians Aaron Smith and Tyler Harris installed a manual transfer switch with a generator interlock, a 50A breaker, a mounted generator inlet with up to 15 ft of feeder, and a 15 ft whip, then commissioned the system with the homeowner. This project was delivered by our Greenville branch, serving the greater area from our Taylors location.
What we installed and configured
- Manual transfer switch and interlock: We reconfigured the main panel so the new generator breaker and the customer’s selected circuits are grouped at the top-left positions. The interlock kit was mounted on the panel face to prevent backfeed and ensure safe, code‑compliant switching.
- Clear panel labeling: We applied code‑compliant labels so it’s easy to identify which breakers to operate during an outage.
- Generator inlet and feeder: From the panel, we installed up to 15 ft of feeder to a permanently mounted generator inlet, located next to the main garage panel for convenient access.
- 15 ft whip and 240V generator cord: A 15 ft whip was provided for quick hook‑up to the inlet. The customer supplied a 10,000W Generac portable generator, and our team supplied the manual transfer switch, inlet, and 240V generator cord to complete the package.
- 50A generator breaker: Sized to support the customer’s selected essential circuits when on generator power.
- System testing and homeowner walkthrough: We tied into the customer’s chosen circuits and verified proper operation with a step‑by‑step demonstration.
Included: 50A breaker, interlock kit, splicing of circuits as needed, up to 15 ft of feeder, mounted generator inlet, and a 15 ft whip. Not included: Conduit (if required) and a portable generator.
How the interlock and manual transfer switch protect your home
During an outage, the interlock and manual transfer switch allow you to safely energize selected circuits from your portable generator while mechanically preventing the utility main and the generator breaker from being on at the same time. This eliminates dangerous backfeed risks, protects your generator and utility workers, and helps keep essential loads running—such as refrigeration, lighting, and key outlets—until utility power is restored.
Whole‑home surge protection at the main panel
We also installed a whole‑house surge protective device (SPD) at the main electrical panel. The SPD diverts excess voltage to ground, helping shield your home’s electrical system and connected appliances from damaging spikes caused by lightning events, grid fluctuations, or heavy equipment cycling.
The installed SPD includes a $10,000, 3‑year warranty for covered home appliances in the unlikely event of device failure. Per the warranty terms, claims are secondary to your existing insurance policy and direct lightning strikes are excluded. Covered equipment generally includes major appliances and hard‑wired devices when protected by a properly connected SPD. Security systems and medical equipment are not included.
