Electrical Panel Upgrade: The Complete Homeowner's Guide
Your electrical panel is the heart of your home's power system. When it can't keep up with modern demands, everything from convenience to safety is affected.
Signs You Need a Panel Upgrade
Frequent Breaker Trips
If you're constantly resetting breakers, your panel is telling you something. This happens when:
- Circuits are overloaded with too many devices
- Your panel capacity is insufficient for your home's needs
- Breakers are worn out and failing prematurely
Flickering or Dimming Lights
When lights flicker as appliances turn on, your panel may be struggling to distribute power evenly. This is especially common in homes with:
- Original 60 or 100-amp panels
- Multiple high-draw appliances
- Added living space or home additions
You're Planning Major Additions
These projects typically require panel upgrades:
- EV charger installation (requires 40-60 amps)
- Hot tub or pool equipment
- Home additions or finished basements
- Kitchen remodels with new appliances
