Who We Are

Generator Wiring from a Duncan, SC Electrical Contractor

Redland Electric LLC is based in Duncan, SC and serves homeowners throughout the Greenville-Spartanburg area, including Greer, Spartanburg, and Simpsonville. We install manual transfer switches and interlock kits for portable and backup generators, along with a generator-ready inlet box outside, so your generator can feed the circuits you choose through your panel instead of through extension cords. This service is for anyone who wants their home set up to switch to backup power safely during an outage, rather than running extension cords through a window.

How We Work

How a Generator Installation Job Goes

From checking your panel to testing the transfer switch or interlock, here's what to expect when Redland Electric wires up your generator.

01Step 1

Assess Your Panel and Power Needs

We look at your electrical panel, available capacity and the best spot for an outdoor inlet box, then talk through whether a manual transfer switch or interlock kit fits your generator and the circuits you want to run before quoting the job.

02Step 2

Install the Transfer Switch or Interlock Kit

We mount the inlet box, run the wiring to your panel, and install the manual transfer switch or interlock kit according to code, keeping you posted as the work progresses.

03Step 3

Test and Walk You Through It

We test the hookup under load to confirm it works the way it should, then show you how to connect your generator and switch over, and answer any questions before we leave.

Frequently asked

Generator Installation Questions

Answers to the questions we hear most from homeowners weighing generator options, permits, and installation details before requesting a quote.

Q1

What's the difference between a transfer switch and an interlock kit?

Both let you safely run a generator through your home's wiring without backfeeding the utility lines. A manual transfer switch is a separate panel wired to the circuits you choose, and you flip those circuits over to generator power during an outage. An interlock kit is a mechanical device added to your existing panel that keeps the main breaker and generator breaker from being on at the same time. Which one makes sense depends on your panel, how many circuits you want backed up and the generator you're using.

Q2

Do you install generator hookups in my area?

Yes, we handle generator hookups for homes throughout Duncan and the greater Greenville-Spartanburg area, including Greer, Spartanburg, Simpsonville, and surrounding towns. If you're not sure your location is covered, just reach out and we'll confirm.

Q3

Do I need a permit or inspection for a generator hookup?

Installing a transfer switch or interlock kit modifies your panel, so it often requires an electrical permit and a local inspection. We'll tell you what applies to your job when we look at your panel.

Q4

What signs mean it's time for a generator hookup?

Frequent outages, a sump pump or medical equipment that can't lose power, or an older panel with no safe way to connect a portable generator are all signs. If you're currently running extension cords through a window during outages, that's a safety risk a proper transfer switch or interlock hookup solves. We can look at your panel and usage to recommend the right setup.

Q5

Should I install a generator myself or hire an electrician?

Connecting a generator to your home's wiring isn't a safe DIY project because a backfeed mistake can energize lines outside your house and endanger utility workers or neighbors. A licensed electrician installs the transfer switch or interlock correctly, confirms your panel can handle the load, and wires it to code. Plugging small appliances into a portable generator with its own cords is fine on your own; wiring it into the house isn't.

Q6

Which hookup is right for my generator?

It depends on your panel, the circuits you want to keep running and the generator you have or plan to buy. We install manual transfer switches and interlock kits for portable and backup generators, and we'll recommend the setup that fits before quoting the job.
