Panel & Service Upgrades — Hood County

Electrical Panel Upgrades in Granbury, TX

Your electrical panel is the heart of your home's power system. Every circuit in your house runs through it, and if your panel is outdated, undersized, or failing, it can cause flickering lights, tripped breakers, and in the worst cases, electrical fires. Twisted B Electric performs panel upgrades throughout Granbury and Hood County, Texas — from 100A to 200A service upgrades to full panel replacements.

Many older homes in the Granbury area still have 100-amp service, which was adequate when homes had fewer appliances and no central HVAC. Today, with modern kitchens, home offices, EV chargers, hot tubs, and shop equipment, 200-amp service is the standard — and often a requirement for major additions or upgrades.

If your home has a Federal Pacific, Zinsco, or Challenger panel, you should have it inspected and likely replaced. These panels have documented safety issues including breakers that fail to trip during overloads. We replace these panels with modern, code-compliant equipment from trusted manufacturers.

Common Questions

Frequently Asked Questions

How much does a panel upgrade cost in Granbury?: A typical 200-amp panel upgrade in the Granbury area runs between $2,500 and $4,500 depending on the scope of work. If you also need a meter base or service entrance upgrade, that adds to the cost. We provide detailed written estimates after inspection so you know exactly what to expect.
How long does a panel upgrade take?: Most residential panel upgrades complete in one day. If meter base work or service entrance upgrades are required, it may take two days. Oncor typically schedules the meter reconnection within 24 to 48 hours of our request.
Do I need to upgrade to 200 amps?: It depends on your current and future electrical loads. If you are adding an EV charger, hot tub, shop equipment, or a generator, you likely need 200-amp service. Many older homes still have 100-amp panels that worked fine for decades but cannot handle modern demand.
Is a Federal Pacific panel dangerous?: Federal Pacific Electric (FPE) panels have a documented history of breakers that fail to trip during overloads, which can lead to electrical fires. Most electricians and home inspectors recommend replacing FPE panels, and some insurance companies require it.
Will I lose power during the upgrade?: Yes, your power will be off during the panel swap, typically four to eight hours. If Oncor needs to disconnect and reconnect the meter, that adds additional downtime. We schedule the work to minimize disruption.
