Quick Answers
Quick Answers About Electrical Panel Upgrades
Clear answers to common questions customers ask before requesting this electrical service.
Can a panel upgrade support an EV charger or home addition?
It can, when additional electrical capacity is needed. A.T. Electric evaluates the existing service and project load before recommending an upgrade.
What happens during a panel-upgrade estimate?
The electrical team reviews the existing panel, available capacity, visible safety concerns, and the planned electrical load before outlining the appropriate scope of work.
Safety First
Signs You Need An Electrical Panel Upgrade
Modern electronics, high-efficiency HVAC units, and EV chargers draw more current than older panels were built to handle. If you experience any of the following symptoms, an immediate evaluation is recommended.
Frequently Tripping Breakers
If running the microwave and toaster simultaneously trips your breakers, your panel is overloaded and struggling to distribute adequate amperage.
Flickering or Dimming Lights
Lights that dip when the air conditioner turns on point to unstable voltage regulation inside the main breaker service connection.
Burning Smells or Warm Panels
A panel door that feels warm or gives off a faint burning plastic odor indicates arcing conductors, loose connections, or melted busbars.
Old Fuse Boxes or Zinsco/FPE Panels
Federal Pacific Electric (FPE) and Zinsco panels have recognized failure rates to trip during overloads, creating documented fire risks that insurance carriers will decline.
Installing EV Chargers or Solar
Level 2 EV chargers require a dedicated 40-50 amp circuit. Older 100-amp panels lack the capacity and breaker slots to add this load safely.
Lack of 3-Prong or GFCI Outlets
If your home still features ungrounded 2-prong outlets, an upgraded panel with AFCI and GFCI circuit breakers brings your electrical foundation up to code.
Value & Protection
Why Upgrade Your Electrical Panel?
Upgrading your electrical panel with A.T. Electric LLC improves daily power stability, protects expensive electronics, and safeguards your household.
Enhanced Family & Home Safety
Worn-out breakers fail to shut off current during short circuits. A modern panel introduces Arc-Fault (AFCI) and Ground-Fault (GFCI) breakers that immediately isolate dangerous electrical faults before a fire can ignite.
Improved Energy Efficiency
Corroded connections and overloaded circuits create electrical resistance, causing your system to pull extra power and waste energy through heat. Upgraded panels optimize current distribution and stabilize voltage drops.
Support for Heavy Modern Appliances
Contemporary homes require 200-amp service to run induction cooktops, dual HVAC compressors, swimming pool pumps, and home theaters simultaneously without flickering or voltage sags.
Prepared for Remodels & Solar
Planning a kitchen remodel, backyard workshop, or solar system? Installing a new panel ensures you have the necessary physical space and busbar capacity for multiple expansion circuits.
Insurance Compliance & Home Value
Many Texas home insurance providers will not write policies on homes with Federal Pacific or Zinsco panels. A certified upgrade provides proof of compliance, increases property appraisal, and reassures home buyers.
Built-in Surge Suppression Ready
Modern breaker boxes allow seamless integration of Type 1 and Type 2 whole-home surge protectors, shielding your equipment from lightning strikes and utility line disturbances.

Helpful Information
Electrical Panel FAQs
How do I know if I have a 100-amp or 200-amp electrical panel?
Check the main circuit breaker located at the very top or bottom of your panel. It typically has a number stamped directly on the switch handle (such as 100, 150, or 200). If you have an older fuse box or cannot locate the main switch, our licensed electricians can perform a quick visual inspection to confirm your current service capacity.
How long does an electrical panel upgrade take?
A standard residential panel upgrade typically takes between 4 to 8 hours to complete. We plan all permits and utility disconnections in advance so that your electrical power is safely reconnected before the end of the day.
Will my power be turned off during the upgrade?
Yes. For safety reasons, the electrical utility provider must disconnect the main power feed from the meter while our electricians remove the old panel, mount the new enclosure, and terminate all branch circuits. Power is restored as soon as the work is verified and inspected.
Why are Federal Pacific (FPE) and Zinsco panels considered dangerous?
Extensive independent safety testing revealed that Federal Pacific Stab-Lok breakers and Zinsco panels frequently fail to trip when an overcurrent occurs. Instead of shutting off power, the breakers can jam, melt, and ignite electrical fires. Most home insurance companies refuse coverage for properties with these panels until they are replaced.
Do I need a city permit for a panel replacement in Mansfield or Arlington?
Yes. Municipal building codes in Mansfield, Arlington, and surrounding DFW cities require a licensed electrical contractor to pull a permit and have an official city inspector sign off on the installation. A.T. Electric LLC manages the entire permit and inspection process on your behalf.
