When to upgrade from 100A to 200A service and why it matters for your home's safety and modern power demands.
Your electrical panel is the heart of your home's power system. An outdated or overloaded panel isn't just inconvenient—it's a serious fire hazard. Here are the 7 warning signs that it's time for an upgrade.
Did You Know?
The National Fire Protection Association reports that electrical failures or malfunctions were the second leading cause of U.S. home fires from 2014-2018, causing an estimated $1.3 billion in property damage annually.
If you're constantly resetting tripped breakers, your panel is telling you it can't handle your home's electrical load. This is especially common when running multiple appliances simultaneously.
What's Normal vs. What's a Problem:
Electrical panels built before 2000 weren't designed for today's electrical demands. Modern homes use 3x more electricity than homes from the 1980s due to computers, smart devices, electric vehicles, and high-efficiency appliances.
Dangerous Panel Brands
These brands are known fire hazards and should be replaced immediately:
When lights dim or flicker as appliances turn on (like the AC, refrigerator, or microwave), your panel is struggling to distribute power properly. This indicates insufficient amperage capacity.
THIS IS AN EMERGENCY. Any burning smell, discoloration, or scorch marks around your panel means wiring is overheating. Turn off your main breaker and call an electrician immediately.
Immediate Action Required
Don't wait if you notice:
• Burning plastic smell near the panel
• Hot to the touch panel cover
• Visible sparks or arcing
• Melted wires or breakers
Planning to install central AC, a hot tub, electric vehicle charger, or remodel your kitchen? These require significant power. A 100-amp panel typically can't support these additions safely.
A 100A panel typically has only 50-60A available for new circuits after accounting for existing loads.
Relying on extension cords and power strips because you don't have enough outlets is a sign your home's electrical system is outdated. An upgraded panel allows you to safely add more circuits and outlets.
Water and electricity don't mix. Rust or corrosion indicates moisture infiltration, which compromises safety and functionality. In coastal San Diego, salt air can accelerate panel deterioration.
