200-Amp Panel Upgrade in Gresham, Oregon

A homeowner in Gresham, Oregon needed more capacity than their old electrical panel could deliver. Heritage Electric handled the full upgrade to a new 200-amp panel, giving the home the power headroom modern households actually need.

The Challenge

Older homes across Gresham and the greater Portland metro were often built with panels rated well below what today’s electrical loads demand. Between kitchen appliances, HVAC equipment, EV chargers, and home electronics, an undersized panel becomes a bottleneck, and in some cases a safety concern. This home’s existing panel was at capacity, and the wall cavity feeding it needed to be opened up to reroute wiring cleanly to a new service.

The Approach

Heritage Electric performed a complete 200-amp panel upgrade, from the initial teardown of the old panel to final connections and cover installation. The wall was opened to access and reorganize the branch circuit wiring, each circuit was re-terminated in the new panel, and breakers were sized and labeled correctly before the system was tested and closed up. The finished installation gives the home a clean, code-compliant panel with room to grow.

Why It Matters

A 200-amp panel upgrade isn’t just about avoiding tripped breakers. It’s the foundation that supports everything else in a modern home, from EV charging to a heat pump to a future addition. Getting the panel right the first time means the homeowner won’t need to revisit their electrical service again for major upgrades down the road.

Project Result

The Gresham home now runs on a new 200-amp panel with organized, correctly matched circuits and a clean finished installation. It’s a straightforward upgrade that solves the capacity problem for good and sets the home up for whatever comes next.
