Panel Upgrade
A standard 200-amp panel upgrade in Raleigh typically takes 4–8 hours on-site, with power off for 3–5 hours. The full process — permit to final inspection — spans about a week. Complex jobs (400A, meter base, older wiring) can run 8–12 hours or two days.
Told your home needs a panel upgrade? The first question is always the same: how long will this take? Fair — most of us work from home, have kids doing homework, or rely on equipment that needs power. Here’s the honest timeline, and the good news: your power will not be off the entire time.
The Panel Upgrade Process, Step by Step
The physical work happens in one day, but the full process is a coordinated sequence between your electrician, Duke Energy, and the city inspector.
“The job itself rarely takes all day. What adds time is the permit, the inspection, and waiting for Duke Energy to restore power — not the electrician’s wrench time.”
Factors That Make a Job Take Longer
Some homes are straightforward — modern wiring, 200A service, an accessible panel. Others have complications that add hours or a second visit.
On-Site Hours by Job Type
Estimated on-site hours in Raleigh, NC. Every range assumes the permit is already approved.
- Single-panel job on a weekday
- You have a generator or battery backup for critical devices
- You have 1–2 days buffer for the permit inspection
- Adding a generator transfer switch at the same time
- Upgrading to 400-amp service
- Older home with knob-and-tube wiring
- Meter base replacement may be needed
What to Expect the Day of Your Upgrade
Morning
We arrive, Duke Energy disconnects at the meter, and the old panel comes out. Charge your devices the night before.
Midday
New panel and breakers go in; every circuit is reconnected, tested, and labeled. Keep the fridge closed — food holds 4+ hours.
Afternoon
Duke Energy reconnects, power is restored, and we walk you through the new panel. The city inspection follows within days — power on.
The Permit and Inspection Timeline in Wake County
The paperwork usually moves faster than people expect — and none of it is your job. Here’s what happens behind the scenes on a Raleigh or Wake County panel upgrade.
Permit filed electronically
We submit through the Raleigh Permit & Development Portal (or the county equivalent). Residential electrical permits are commonly approved within 1–2 business days; busy seasons can add time.
Duke Energy coordination
Disconnect in the morning, reconnect after testing — scheduled by us in advance. This is the piece homeowners can’t book themselves, and it’s why DIY panel swaps stall.
City inspection, power on
The inspector checks the work 1–3 business days later — about 15 minutes, power stays on. A correction, if one ever comes up, is a technical fix we return for at no charge.
Why the permit matters: unpermitted panel work voids insurance claims, surfaces on pre-sale inspections, and skips the one independent check that protects your family. Every Electric All Pro upgrade includes it — no exceptions.
How to Prepare Your Home for Upgrade Day
Fifteen minutes of prep the night before makes the outage painless.
- Charge phones, laptops, and battery banks the night before
- Plan around medical equipment — tell us in advance and we’ll sequence the outage
- Keep fridge and freezer doors closed (food holds 4+ hours)
- Clear a 3-foot working space around the panel
- Set garage doors to manual if the opener is on the affected circuit
- Work-from-home? Plan a café morning or a hotspot
- Kennel or gate pets away from the work area
- Note your Wi-Fi router circuit — it goes down with the power
In Raleigh’s July heat, no power means no AC for a few hours. We book early-morning starts in summer so the house is cool again by afternoon — ask for the first slot.
Frequently Asked Questions
Clear answers to the most common questions about panel upgrade timelines.
? How long does a panel upgrade take in Raleigh, NC?
A standard 200-amp panel upgrade typically takes 4 to 8 hours on-site, with power off for 3 to 5 of those hours. Complex jobs — older homes, 400-amp upgrades, or meter base replacements — can run 8 to 12 hours or take two days.
? How long will my power be off?
Usually 3–5 hours for a standard upgrade. Power goes off when Duke Energy disconnects in the morning and comes back the same day after the new panel is tested and reconnected.
? How long does the whole process take, start to finish?
About a week: 1–2 days for the permit, one day of on-site work, and a city inspection 1–3 business days later. The inspection takes about 15 minutes and your power stays on.
? Can I stay home during the upgrade?
Yes — most homeowners do. Plan for no power during the work window: charge devices, keep the fridge closed, and plan around medical equipment or work-from-home needs.
? What if my home has older wiring?
Pre-1970 homes with aluminum or knob-and-tube wiring often need branch-circuit prep before the new panel goes in. We identify this during the estimate so the timeline never surprises you.
? Does the inspection delay using my power?
No. Power is restored the same day as the install. The city inspection happens 1–3 business days later with power on — it verifies compliance, not operation.
? What does a panel upgrade cost?
A standard 200A upgrade in Raleigh runs $2,000–$4,500 depending on home age, wiring condition, and meter base requirements — permit and inspection always included.
? Do I need to be home during the upgrade?
An adult should be present or reachable, and we need clear access to the panel and meter. Many homeowners work from a coffee shop during the outage window and return for the walkthrough.
? Can the upgrade happen on a weekend?
Often, yes — we schedule weekend installs when Duke Energy disconnect slots allow. The city inspection still lands on the next business days, with your power on.
