Electrical Service Upgrade in Lawrenceville, GA

An electrical service upgrade increases the amperage your utility delivers to your home — typically from 100 to 200 amps — by replacing the meter base, service entrance cable, and main panel. A service upgrade isn't just a bigger panel — it's more capacity flowing into your house in the first place, from the meter base all the way to the main breaker. We start with a load calculation so the upgrade is justified by what you actually need, not just the biggest number on the price list, and we handle the utility coordination so the cutover goes smoothly.

Service upgrade vs. panel replacement

They often happen together but aren't the same thing. A panel replacement swaps the breaker box while keeping the existing service size. A service upgrade increases capacity and typically replaces the meter base and service-entrance equipment too, and requires utility coordination to disconnect and reconnect. If your panel is fine but undersized, or aging but the service is adequate, we'll tell you which you actually need.

100-amp vs. 200-amp: how to know when it's time

If your Lawrenceville home still has 100-amp service, you'll start feeling it when you add modern loads. Central air conditioning alone can draw 30–50 amps. Add an electric range (40–50 amps), an EV charger (40 amps), and a heat pump water heater (30 amps), and you're well past what 100 amps can safely deliver. The signs show up as breakers tripping when two big loads run together, lights dimming when the AC kicks on, or the main breaker getting warm.

A 200-amp upgrade gives you room for today's loads and tomorrow's — the cost difference between 200 and 300 amps rarely justifies the jump for a single-family home, so 200 is the standard residential upgrade.

What a service upgrade involves

A service upgrade is more than a panel swap. We replace the meter base (the utility's meter socket), the service entrance cable between the meter and the panel, the panel itself, the grounding electrode system and, if it's overhead service, the mast and weatherhead. The utility disconnects power for the cutover and reconnects when the inspection passes. In Gwinnett County, the permit, inspection and utility coordination typically add two to three business days to the timeline, and we handle all of it so you don't have to call the utility yourself.

Signs your electrical service is undersized

The clearest sign is a main breaker that trips under normal household load — not a single-circuit breaker, but the big one at the top of the panel. Other signs: lights dimming when the AC or dryer starts, a meter base that's visibly corroded or cracked, or a utility sticker showing a service rating lower than 200 amps. If you're planning an addition, a pool heater or an EV charger, ask us for a load calculation before you commit — adding a 50-amp circuit to a panel that's already at capacity doesn't work, and discovering that mid-project costs more than discovering it upfront.
