A 100-amp panel was standard when a house had a furnace, a fridge, and not much else pulling power. Add central air, an EV charger, and a kitchen full of appliances, and that same panel starts tripping breakers or simply can’t add the circuit you need. This is not a DIY job — it involves the utility’s live service drop and a permitted inspection — so this guide is about knowing what a fair quote looks like, not how to do it yourself.
What Drives the Price
The panel and breakers themselves are a small piece of the bill. Labor, permitting, and — critically — whether the utility has to get involved to upgrade the service drop or meter are what separate a $1,500 job from a $6,000 one.
Electrician rates vary more than almost any other trade in this guide: $65 an hour in rural, low-cost areas versus $150+ an hour in NYC, San Francisco, or Honolulu. A quote that looks high next to an online average is often just an honest reflection of local labor cost, not a markup.
| Scope | Typical Installed Cost |
|---|---|
| 100A to 200A panel upgrade, standard | $1,500 – $4,000 |
| 100A to 200A with utility service work | $3,000 – $6,000 |
| Full upgrade in a high-labor-cost market | $5,000 – $6,000+ |
- New 200A panel: $700–$900
- Breakers: $300–$500
- Labor (8–10 hours): $800–$1,400
- Permit and inspection: $250–$500
Why This One Isn’t a DIY Project
Every other guide on this site tells you where a homeowner can reasonably save money by doing part of the work themselves. This is the exception. The main panel is the one point in the house where a mistake is lethal, not just expensive, and most jurisdictions require the utility to physically disconnect service before anyone opens the panel — a step a homeowner can’t do themselves. Pull a permit and use a licensed electrician for this one; it’s also usually required for the inspection your homeowner’s insurance will eventually ask to see.
How to Get a Fair Quote
Get at least two quotes and ask each electrician the same direct question: does your existing service entrance cable and meter base need replacing, or just the panel? That single answer explains most of the spread between a $2,000 quote and a $5,000 one. If a quote is unusually low, confirm it includes the permit and inspection fee — some contractors quote labor and materials only and add the permit as a surprise line item.
If your only symptom is a breaker that trips under normal load, ask an electrician whether the fix is really a full panel upgrade or just a dedicated circuit for the one appliance causing it — a $300 fix sometimes gets sold as a $3,000 one to someone who doesn’t ask.
