100 to 200 Amp Combo Panel Upgrade Done Right

Here's what an overloaded, aging 100 amp setup looks like when it's finally reached its limit. Two separate weathered enclosures, exposed and tangled wiring, debris buildup around the components - the kind of setup that keeps property owners up at night. Not because it's inconvenient, but because it's a genuine safety risk.

We pulled all of that out and replaced it with a single new 200 amp Square D combo unit. One clean enclosure, properly grounded, with a full bank of breaker slots ready to handle modern electrical demand. The difference isn't just cosmetic - it's the difference between a system that's barely holding on and one that's built for what properties actually need today.

A 100 amp service made sense decades ago. But with today's appliances, HVAC systems, EV chargers, and everything else drawing power, it's just not enough anymore. Tripped breakers, flickering lights, and circuits that can't keep up are all signs your panel is telling you something. Upgrading to 200 amps gives you the headroom to run your property without constantly managing what's plugged in.

The Square D combo meter-main is a solid choice for this kind of work. It combines the meter socket and the main breaker panel into a single unit, which cuts down on the number of components that can fail and makes the whole service entrance cleaner and easier to work with down the road. It's a trusted name with a proven track record in residential and commercial applications.

If your panel is pushing 30, 40, or more years old - or if you're still running a 100 amp service - it's worth having someone take a look. These aren't upgrades you do because something already went wrong. You do them before something goes wrong.
