100 to 200 Amp Electrical Panel Upgrade Done Right

A 100-amp panel was the standard for homes built decades ago. But modern homes are a different story. EV chargers, central AC, high-demand appliances, home offices - the list goes on. When a home is running all of that through an undersized panel, you start seeing tripped breakers, dimming lights, and circuits that just can't keep up. That's a sign it's time for a service upgrade.

Here's what we were working with on this one - an older 100-amp panel that had clearly hit its limit. The original enclosure was compact, the wiring was crowded, and there was simply no room to grow. We pulled the old panel, opened up the wall to give us the proper footprint, and got to work installing a new 200-amp Eaton panel with a full breaker layout that actually matches the home's needs.

On the exterior, we also installed a new emergency disconnect alongside the meter - a code requirement in many areas now, and honestly just good practice. It gives the home a clean, proper service entrance and makes future utility work or emergency shutoff straightforward. Every connection was made cleanly and securely, with circuits labeled and organized so the homeowner knows exactly what's what.

Doubling the service capacity from 100 to 200 amps isn't just about handling today's load - it's about not painting yourself into a corner. Want to add a hot tub later? Charge an electric vehicle? Run a workshop? A 200-amp service gives you that flexibility without worrying about whether the panel can handle it. It also makes the home more attractive to buyers and easier to insure.

If your panel is old, undersized, or you're not sure what it's rated for - that's worth looking into. An outdated panel isn't just an inconvenience. It can be a real safety concern.
