Everything you need to know about Panel Upgrades, electrical requirements, and what to expect from your project.
Common signs include frequent breaker trips, flickering lights, a warm or buzzing panel, an outdated fuse box, or wanting to add an EV charger, solar, or major appliances your current panel can’t support. If you’re seeing any of these, a free inspection can confirm what’s needed.
Most residential panel upgrades (100A to 200A, or 200A to 400A) are completed in 1–2 days, depending on your home’s electrical setup, panel size, and whether utility coordination or permits add extra time.
Yes. Panel upgrades require permits and inspection to meet current electrical codes. We handle the permitting, utility coordination, and inspection process for you as part of every installation.
It depends on your home’s size and power demands. Most modern homes benefit from at least a 200A panel, especially if you’re adding an EV charger, solar, a Tesla Powerwall, or other high-draw systems. Larger homes or those planning multiple high-power additions may need 400A. A home assessment will pinpoint the right fit.
Yes. An updated, code-compliant electrical panel improves safety, supports modern systems like EV chargers and solar, and is a selling point for buyers — outdated 100A panels or fuse boxes can actually lower resale value or fail inspection.
In most cases, power is only interrupted for a few hours during the actual panel swap, and we schedule the outage window in advance so you know exactly when to expect it. We coordinate with the utility company as needed to keep the disruption as short as possible.
Yes. We can size and design your new panel with extra capacity and space for future circuits, so you won’t need another upgrade when you’re ready to add an EV charger, solar system, or battery storage down the road.
