Your electrical panel does far more than hold breakers — it’s the control center that distributes power safely throughout your home. As homes add EV chargers, heat pumps, modern appliances, and smart technology, older panels often struggle to keep up.
At Smiley Electric, panel upgrades and replacements are some of the most common projects we complete for homeowners in Portland, Beaverton, Lake Oswego, Hillsboro, and Tigard. Here’s how to know which type of panel work your home needs.
Panel Upgrade vs. Panel Replacement vs. New Panel Installation
Panel Upgrade
A panel upgrade increases your home’s electrical capacity, most commonly:
- From 100 amps to 200 amps
- From 200 amps to 400 amps (large homes, ADUs, multiple EVs)
Upgrades are ideal if you’re:
- Installing an EV charger
- Adding a heat pump or HVAC system
- Remodeling a kitchen or ADU
- Experiencing frequent breaker trips
Panel Replacement
Panel replacement means swapping out the existing panel without increasing amperage. This is often required when the panel itself is unsafe or obsolete.
Common reasons for replacement:
- Federal Pacific (FPE), Zinsco, Pushmatic, or Split-Bus panels
- Rust, corrosion, or overheating
- Breakers that won’t reset or trip improperly
Even if the amperage stays the same, replacing an unsafe panel is critical for fire prevention and insurance compliance.
New Panel Installation
A new panel installation is typically required when:
- Adding an ADU or detached structure
- Relocating the panel for code clearance
- Converting from fuse box to breaker panel
- Installing a subpanel or second main panel
New installations require careful planning, permits, and coordination with the utility provider.
Signs You Need Panel Work
You may need an upgrade or replacement if you notice:
- Breakers tripping frequently
- Flickering or dimming lights
- Warm or buzzing panel
- Burning smells near the panel
- Limited breaker space
- Insurance or home inspection flags
Older homes in Portland and Beaverton often still have undersized 100-amp panels, which are no longer sufficient for modern electrical loads.
What’s Included in a Professional Panel Installation
A proper panel project includes:
- Load calculation for current and future needs
- Proper grounding and bonding
- AFCI and GFCI breaker installation where required
- Whole-home surge protection (recommended)
- Clear labeling of all circuits
- Permit handling and inspection coordination
Smiley Electric ensures all work meets NEC and Oregon Electrical Specialty Code.
How Much Does a Panel Upgrade or Replacement Cost?
Typical price ranges in the Portland metro area:
- Panel replacement (same amperage): $2,500–$3,500
- 100A → 200A upgrade: $3,000–$5,500
- 200A → 400A upgrade: $5,000–$8,000+
- New panel installation: varies by scope and location
Final cost depends on panel location, service condition, grounding requirements, and utility coordination.
Permits, Inspections & Utility Coordination
Panel work always requires:
- Electrical permits
- City or county inspections
- Coordination with PGE or Pacific Power for service shutoff and reconnection
Smiley Electric handles all of this, so homeowners don’t have to manage the logistics.
