If your Oklahoma City home still has a 60- or 100-amp panel, a fuse box, or a breaker brand with a bad track record, an electrical panel upgrade is one of the most important safety improvements you can make. Our electricians handle panel upgrades and panel replacements across Oklahoma City, from older homes in Mesta Park, Heritage Hills, Crown Heights and The Village to newer neighborhoods in north and south OKC. We size the new panel to the way you actually use power today, handle the permit, and coordinate with OG&E so the job runs smoothly.
Signs Your OKC Home Needs a Panel Upgrade
- Your home has 60- or 100-amp service. Many older Oklahoma City homes were built with service that was fine for a few lights and a fridge but not for central air, a modern kitchen and an EV.
- You still have a fuse box, or a panel with screw-in fuses for some circuits.
- Your panel is a Federal Pacific (Stab-Lok), Zinsco or Sylvania-Zinsco. These brands have well-documented problems with breakers failing to trip.
- Breakers trip often, especially when the AC kicks on during an Oklahoma summer.
- Lights dim when large appliances start.
- The panel is warm, buzzes, smells hot or shows rust or scorch marks.
- There's no room for new breakers, and you're relying on tandem breakers or extension cords.
- You're adding major load, such as a heat pump, EV charger, hot tub, shop or addition.
Panel Upgrade vs. Panel Replacement
These terms get mixed up, so here's the difference:
- Panel replacement swaps the existing panel for a new one at the same amperage. This is common when a panel is damaged or is a problem brand, but the home's service size is still adequate.
- Panel upgrade (service upgrade) increases your home's capacity, most often from 100 to 200 amps. This usually includes a new panel, a new main breaker, and often a new meter base, service entrance cable and grounding.
Our article on electrical panel replacement vs. upgrade in Oklahoma goes into more detail.
100 Amp vs. 200 Amp for Oklahoma City Homes
Most OKC homes today are best served by 200-amp service, especially homes with central air, electric ranges or dryers, or any plans for EV charging. A 100-amp panel can work for a smaller home with gas appliances and modest loads, but it leaves little headroom. We run a load calculation before recommending a size, so you're not paying for capacity you don't need. See our guide to 100 amp vs. 200 amp panels in Oklahoma.
What an Electrical Panel Upgrade Includes
- Load calculation and walkthrough. We look at your current panel, service entrance, meter and grounding, and list your existing and planned loads.
- Written quote. Clear scope and price before anything starts.
- Permit. We pull the electrical permit through the City of Oklahoma City.
- Utility coordination. We schedule the disconnect and reconnect with OG&E.
- Installation. Remove the old panel, install the new panel and main breaker, transfer and label circuits, and update grounding and bonding to current code. AFCI and GFCI protection is added where required.
- Inspection. The city inspects the work before OG&E restores permanent service.
- Walkthrough. We show you the new panel and the circuit directory.
Most panel replacements and upgrades are completed in a single day of work. Inspection and utility scheduling can add a day or two.
Electrical Panel Upgrade Cost in Oklahoma City
Costs vary with amperage, the condition of the service entrance and meter base, the distance between meter and panel, and how many circuits need AFCI or GFCI protection. As a general guide:
- Like-for-like panel replacement: typically in the low thousands
- 100 to 200 amp service upgrade: typically low to mid thousands, more if the meter base, mast or service cable must be replaced
- Fuse box conversions: similar to a service upgrade, sometimes more if older circuits need repair
We confirm everything in writing before work begins. Our panel upgrade cost guide for Oklahoma breaks this down further.
Why Oklahoma City Homes Need Upgrades
A big share of Oklahoma City's housing was built before the 1980s, when typical household loads were much smaller. Long, hot summers keep air conditioners running for months, which is hard on undersized panels. Severe spring storms and lightning also stress electrical equipment, so many homeowners add whole-home surge protection at the panel during the upgrade. And as more OKC drivers switch to EVs, a 200-amp panel is often the step that makes a Level 2 EV charger possible.
