Smart Electrical Panels in Portland: Span, Leviton & Why Upsizing Your Panel Matters

Written by the team at Nexus Electrical Group, licensed electricians (Oregon CCB #226988) serving Beaverton and Portland, Oregon, with 30 years of experience in the electrical field. Published July 25, 2026 · Last updated July 25, 2026

A smart electrical panel — like the Span Panel or Leviton’s Smart Load Center — monitors and controls every circuit in your home from an app, and it works best paired with properly sized 200-amp service. For Portland and Beaverton homeowners adding EV chargers, heat pumps, and induction ranges, that combination is the safest, most future-proof way to power a modern home.

In this guide, our licensed electricians break down how smart panels from Span, Leviton, Schneider (Square D), and Eaton compare, why upsizing an older 100-amp panel is a safety decision — not just a convenience — and what to expect on cost and permits across the Portland metro.

What is a smart electrical panel?

A smart electrical panel is a breaker box that measures and manages electricity circuit by circuit in real time. Instead of a row of breakers you only touch when one trips, a smart panel shows you exactly what every circuit is drawing, lets you switch circuits on or off from your phone, and can automatically shed low-priority loads when demand spikes.

There are three main ways to get there:

  • A full smart panel (Span). The Span Panel replaces your breaker box entirely: a 200-amp panel with 32 individually monitored and controllable circuits, plus deep integration with batteries and solar from Tesla Powerwall, Enphase, SolarEdge, and Generac. It carries a 10-year warranty and UL 3141 certification for load management.

  • Smart breakers in a standard panel (Leviton). Leviton’s Smart Load Center lets you mix ordinary breakers with 2nd Gen Smart Circuit Breakers (up to 60 amps, including AFCI and GFCI versions). Through the My Leviton app you get remote on/off, scheduling, load shedding, and whole-home energy monitoring — without replacing every breaker at once.

  • Smart options from legacy brands. Schneider Electric’s Square D Energy Center and Eaton’s smart breakers bring similar monitoring and control to two of the most established panel brands in the industry — a good fit if you want to stay within an existing equipment ecosystem.

Why is upsizing your electrical panel a safety issue?

An undersized or outdated panel is not just inconvenient — it’s a hazard. According to the Electrical Safety Foundation International (ESFI), electrical fires account for an estimated 51,000 home fires each year in the U.S. Panels running near capacity run hotter, trip more, and leave no safe room for new circuits.

Many older Portland and Beaverton homes — especially pre-1980 houses in neighborhoods like Irvington, Ladd’s Addition, and central Beaverton — still run on 60- to 100-amp service that was never designed for today’s loads. The NFPA notes that under the 2020 National Electrical Code, modern all-electric homes with EV charging, heat pumps, and induction cooking typically call for 200-amp service.

Warning signs your panel is overdue for an upgrade:

  • Breakers that trip frequently, or lights that flicker and dim when large appliances start.

  • A panel that feels warm to the touch, buzzes, or shows rust or scorch marks.

  • Power strips and extension cords doing permanent duty because you’re out of circuits.

  • A Federal Pacific or Zinsco brand panel — these have documented failure risks and should be replaced regardless of symptoms.

If any of these sound familiar, start with our electrical panel upgrade service — the assessment is free.

How much load does an EV charger add to a panel?

A Level 2 home EV charger typically draws 32–48 amps on a dedicated 240-volt circuit — on a 100-amp panel, that single appliance can claim close to half your home’s total capacity. A 48-amp hardwired charger requires a 60-amp breaker all by itself.

The payoff is real: according to ENERGY STAR and the U.S. Department of Energy, a Level 2 charger adds roughly 20–30 miles of range per hour of charging, versus about 3–5 miles from a standard 120-volt outlet. That’s why every one of our EV charger installations in Beaverton and Portland starts with a load calculation — and why many EV owners upsize to 200-amp service and add a smart panel in the same visit.

Span vs. Leviton vs. other smart panels: which is right for your home?

Span is the best fit for whole-home control and battery backup; Leviton is the most flexible way to add smart features to a conventional panel over time; Square D and Eaton suit homes standardized on those brands. Here’s how they compare:

  • What it is: Span Panel — full 200-amp smart panel replacement, 32 circuits. Leviton Smart Load Center — standard panel that accepts modular smart breakers (up to 60A each). Square D Energy Center / Eaton — smart panel or smart breakers from legacy brands.

  • Monitoring & control: Span — every circuit individually, per-circuit on/off and priorities in the Span app. Leviton — per-circuit for smart breakers; remote on/off, schedules, alerts in My Leviton app. Square D / Eaton — circuit monitoring and control via brand apps.

  • Solar & battery: Span — Tesla Powerwall, Enphase, SolarEdge, Generac PWRcell. Leviton — solar, battery, and generator monitoring via CT sensors. Square D / Eaton — strong within Schneider / Eaton ecosystems.

  • Typical installed cost: Span — ~$5,500–$8,000 (industry reviews). Leviton — lower entry cost; add smart breakers as needed. Square D / Eaton — varies by configuration.

  • Best for: Span — whole-home control, battery backup, EV-heavy homes. Leviton — budget-flexible retrofits and phased upgrades. Square D / Eaton — matching existing brand equipment.

We install all of these. If you want the deepest control and outage resilience, see our Span Smart Panel installation service. Pair it with a backup generator or battery and the panel will automatically keep essentials running when Portland’s winter storms knock out power.

Can a smart panel help you avoid a panel upgrade?

Sometimes — and we’ll tell you honestly when it can. Smart panels and NEC-recognized load-management systems can pause or throttle an EV charger when the rest of the house is drawing heavily, which in some homes safely defers a service upgrade.

But load management can’t fix a panel that’s already unsafe. If your panel is 40+ years old, uses fuses, is a Federal Pacific or Zinsco, or is already running hot, upsizing is the right call — and pairing the new 200-amp service with a smart panel gives you both headroom and intelligence. That’s the belt-and-suspenders setup we recommend for most EV households.

What do smart panels and panel upgrades cost in Portland?

Industry reviews put a professionally installed Span Panel at roughly $5,500–$8,000, while Leviton’s approach starts lower because you add smart breakers only where you want them. A conventional 200-amp panel upgrade typically runs $3500-$4500, and combining the upgrade with a smart panel in one visit saves on labor.

Every panel replacement and service upgrade in our area requires a residential electrical permit and inspection — see the City of Portland’s permit requirements. Nexus Electrical Group handles the permit and inspection on every job, in Portland, Beaverton, and across Washington County. Most straightforward upgrades are done in a single day.

Frequently asked questions

What does a smart electrical panel do?

A smart electrical panel monitors and controls every circuit in your home in real time. From an app, you can see exactly what each circuit is using, switch circuits on or off remotely, set schedules, and automatically shed low-priority loads so high-demand appliances like EV chargers never overload your service.

Is a 100-amp panel enough for an EV charger?

Often not. A Level 2 EV charger draws 32–48 amps on a dedicated 240-volt circuit, which can claim close to half of a 100-amp panel’s capacity. A licensed electrician performs a load calculation to confirm; many Portland homeowners upgrade to 200-amp service when adding a charger.

Do I have to replace my whole panel to get smart features?

No. The Span Panel is a full panel replacement, but Leviton’s Smart Load Center lets you mix standard and smart circuit breakers in the same panel, so you can add remote control and energy monitoring circuit by circuit as your budget allows.

Does the Span Panel work with solar and home batteries?

Yes. Span integrates with major battery and solar brands, including Tesla Powerwall, Enphase, SolarEdge, and Generac PWRcell. During an outage it can automatically prioritize critical circuits so your battery backup lasts longer — a real advantage during Portland-area winter storms.

Do I need a permit to upgrade an electrical panel in Portland or Beaverton?

Yes. Panel replacements, service upgrades, and smart panel installations require a residential electrical permit and inspection in Portland, Beaverton, and throughout Oregon. Nexus Electrical Group pulls the permit and coordinates the inspection as part of every installation.

How long does a 200-amp panel upgrade take?

A straightforward panel or service upgrade is usually a one-day job, with power off for part of that day. Adding a smart panel like Span at the same time typically fits in the same visit, since the old panel is already coming off the wall.

How do I know if my current electrical panel is unsafe?

Watch for breakers that trip frequently, lights that flicker when appliances start, a panel that feels warm or buzzes, and reliance on power strips. Federal Pacific and Zinsco panels should be replaced regardless of symptoms due to documented failure risks. When in doubt, get a professional assessment.
