Why Panel Upgrades Matter
Most older Maine homes are running on 100-amp service — wired before heat pumps, generators, and EV chargers existed. If you want to add any of those, a 200-amp upgrade isn't optional. It's the first step.
Generators, heat pumps, and EV chargers all require dedicated 240V circuits and enough panel capacity to run them safely. A 100-amp panel built in the 1970s wasn't designed for any of that. A 200-amp upgrade makes your home ready.
Overloaded panels, Federal Pacific breakers, and aluminum wiring are leading causes of house fires. An outdated panel that trips constantly or runs hot isn't just inconvenient — it's a liability. Upgrading removes the risk.
Home inspectors flag undersized panels. Buyers ask about it. Lenders require it on FHA and VA loans. A 200-amp panel is a selling point — it tells buyers the home is ready for modern living without a surprise expense at closing.
If your breakers trip when you run the microwave and the dryer at the same time, your panel is maxed out. A 200-amp service gives you the headroom to run your home the way you actually live in it — without constantly resetting breakers.
Upgrading to 200-amp today means you won't hit a capacity wall when you add a heat pump next year or an EV charger the year after. Do it once, do it right, and your home is ready for whatever comes next.
Unpermitted electrical work can void your homeowner's insurance and create problems at resale. Every panel upgrade we do is permitted, inspected by the local authority, and documented — so you're covered and your work record is clean.
Free estimates — we'll assess your current service, tell you exactly what's needed, and give you a clear price.
What We Handle
Whether it's a straight 200-amp upgrade, a full service change with meter base, or a subpanel for a garage or addition — CDS handles every step. One licensed electrician, one crew, start to finish.
Upgrade from 100-amp to 200-amp service — new panel, breakers, and connections. The standard upgrade for homes adding generators, heat pumps, or EV chargers. Permitted and inspected to current NEC code.
Full service change from the weatherhead down — new meter base, service entrance cable, and panel. Required when the existing meter base or service entrance is outdated, damaged, or undersized by the utility.
Adding a garage, shop, barn, or finished basement? A subpanel fed from the main panel gives you a dedicated breaker box at the new space — without running individual circuits all the way back to the house.
Call Dereck — he'll assess your panel, tell you exactly what's required, and give you a straight price on the spot.
