When You Need an Upgrade
If you have a 100-amp panel and want to add a Tesla charger AND keep central AC, you're often right at the edge of a load calculation. EV chargers, mini-splits, and electric ranges all add up fast. Federal Pacific and Zinsco panels should be replaced regardless — they're well-documented fire hazards and many insurance companies won't renew policies on homes that still have them.
Frequently Asked Questions
How long is the power out during a panel upgrade?
Typically 4–8 hours. We coordinate with OG&E for the disconnect and reconnect, do the swap during the day, and have you back up by evening.
Do I need a permit?
Yes — every panel upgrade requires a city permit and final inspection. We handle it all and meet the inspector on site.
How much does a 200-amp panel upgrade cost?
Most 100A→200A residential upgrades run $1,800–$3,500 depending on whether the meter base, service entrance, and grounding also need updating. We give a flat-rate quote up front.
Will my insurance company care?
If you currently have a Federal Pacific or Zinsco panel, yes — many insurers won't renew or will charge higher premiums. An upgrade can lower your homeowner's insurance.
