About Redland Electric

Panel Upgrades for Homes in the Greenville-Spartanburg Area

Redland Electric LLC is based in Duncan, SC and handles panel upgrades for homeowners throughout Greenville, Spartanburg, Greer, Simpsonville and the surrounding towns. A panel upgrade usually means replacing an old or undersized panel with one that has more capacity and modern breakers, often to add safety margin, support new loads like an EV charger or generator, or clear out an outdated panel type that no longer meets code. This service is for anyone dealing with a panel that's tripping breakers, running hot, missing capacity for an addition, or simply old enough that parts and safety are a concern.

The Process

How a panel upgrade gets done

From the first look at your panel to a finished, inspected installation, here's what to expect.

01Step 1

Assess the panel and quote the scope

We look at your existing panel, wiring, and current load, note any outdated or unsafe components, and put together a clear quote for the upgrade before any work starts.

02Step 2

Install the new panel and coordinate inspection

Once scheduled, we coordinate the utility disconnect, remove the old panel, install the new one with properly sized breakers, and arrange the required inspection.

03Step 3

Test circuits and walk through the finished work

We test every circuit, confirm the panel is labeled correctly, answer any questions, and leave the work area clean.

Frequently asked

Panel Upgrade Questions, Answered

Straight answers on cost, timing, permits, and whether your panel needs repair or full replacement.

Q1

What affects the cost of a panel upgrade?

Cost mainly depends on the new panel's amperage, how much the existing wiring needs to be adapted, whether the meter base or service entrance also needs work, and any permit fees. We look at all of this during a site visit so the quote reflects your actual panel, not a generic estimate.

Q2

What are the signs my panel needs an upgrade?

Common signs include breakers that trip often, buzzing or humming from the panel, an outdated panel or old fuse box, flickering lights or appliances that don't run properly, and burning smells or visible damage, which need immediate attention. An upgrade is also worth considering if you're adding an EV charger, new lighting or high-capacity appliances, or planning a renovation. We can assess your panel and recommend the right fix.

Q3

Should I repair my panel or replace it entirely?

It depends on the condition of the panel and what's wrong with it. If the panel is a known problem type like Zinsco or Federal Pacific, has signs of overheating, or is simply too small for your home's load, full replacement is usually the safer long-term fix rather than patching individual breakers. A straightforward issue like a single failed breaker or a loose connection can often be repaired without replacing the whole panel. We'll look at the actual panel and wiring before recommending one over the other.

Q4

Can I upgrade a panel myself or do I need a licensed electrician?

No, panel work should be done by a licensed electrician. A panel upgrade involves working at the main service disconnect and sometimes coordinating a temporary utility shutoff, and mistakes here can cause fire risk or get flagged during inspection. It also needs to pass local code and inspection, which a licensed electrician is set up to handle. We handle the work from start to finish and make sure it's done up to code.

Q5

Do you handle old panel types like Zinsco or Federal Pacific?

Yes, we work on older panel brands including Zinsco and Federal Pacific, both of which have well-documented breaker failures and are commonly flagged during home inspections or insurance reviews. Fuse boxes fall into the same category since they're outdated and often can't support modern electrical loads. Replacing these with a current panel resolves the underlying issue rather than just swapping parts.

Q6

How long does a panel upgrade usually take?

It varies by scope, panel size, whether you're going from 100 amp to 200 amp service, adding a sub panel, and whether the service entrance or meter base also needs work. Most upgrades involve a full-day commitment plus scheduling for the utility disconnect and inspection, but the exact timeline depends on what your home needs. We'll give you a realistic estimate once we've seen the panel and discussed your plans.
