Signs You Need an Electrical Panel Upgrade

Your panel is your home’s electrical backbone. These warning signs mean it’s time to call a licensed electrician:

• Breakers that trip frequently. An occasional tripped breaker is normal. Breakers that trip weekly — or that you’ve learned to “manage” by not running certain appliances together — signal that your panel is maxed out and can’t handle your actual load.
• Flickering or dimming lights. If lights dim when the refrigerator compressor kicks on or when you run the microwave, your panel isn’t delivering stable power. This stresses appliances and can shorten their lifespan.
• A fuse box instead of a breaker panel. Fuse-based panels are obsolete, a common insurance disqualifier, and a clear sign your service entrance hasn’t been updated in decades. Replacement is almost always the right call.
• You’re planning a major addition or upgrade. Adding an EV charger, a heat pump, a hot tub, or finishing a basement or ADU all require dedicated circuits. If your panel is already near capacity, you’ll need an upgrade before any of that work can begin. Hillsboro homeowners adding EV chargers can learn more about our EV charger installation in Beaverton — we routinely handle both in a single project.
• Your home has a Federal Pacific or Zinsco panel. These brands have well-documented safety deficiencies — breakers that fail to trip under overload conditions — and many insurers refuse to cover homes that still have them. If you’re unsure what brand your panel is, we can identify it during a free assessment.

100-Amp vs. 200-Amp Panel: What’s the Difference?

When most Hillsboro homeowners hear “panel upgrade,” they’re thinking about moving from a 100-amp service to a 200-amp service. Here’s what that actually means:

100-Amp Panel

• Standard in homes built before the 1980s
• Adequate for basic lighting, appliances, and a single HVAC system
• Insufficient for EV chargers, electric ranges, heat pumps, or home additions
• Often paired with outdated wiring that may need evaluation alongside the panel
• May trigger insurance surcharges or coverage denials in older configurations

200-Amp Panel (Recommended for Most Hillsboro Homes)

• The modern standard for single-family homes
• Provides ample capacity for current loads plus future expansion
• Required before installing a Level 2 EV charger or whole-home generator transfer switch.
• Supports home office equipment, multiple HVAC zones, and high-draw appliances simultaneously
• Typically increases home resale value and satisfies most insurer requirements

Some larger homes — particularly those with electric heat, multiple EV chargers, or extensive shop equipment — may benefit from a 400-amp service. We’ll assess your actual load during your free on-site visit and recommend only what your home genuinely needs.
