Panels do not last as long in Cohasset as they do ten miles inland, and the reason is the air. Salt carried off the harbor and the open water gets inside enclosures and settles on the bus bar, the breaker contacts and the lugs. It shows up as white or green powder and rust at the bottom of the can, and every bit of it adds resistance to a connection that was designed to carry current cleanly.
Resistance makes heat. Heat loosens connections further, and a loose connection in a panel is how you end up with scorched breakers, flickering circuits, or a service call at midnight. The frustrating part is that none of it is visible with the cover on, so a panel can look untouched from the laundry room and be well along on the inside.
We replace panels in Cohasset regularly, and the job is not just swapping a box. It is sizing the service to what the house actually draws today, protecting the new equipment against the same coastal conditions that took out the old one, and getting the permit and inspection done cleanly.
Signs your Cohasset panel needs attention
- Rust, corrosion, or white or green residue anywhere inside the enclosure
- Breakers that trip repeatedly, or one that feels warm to the touch
- A buzzing, crackling or humming sound from the panel
- A panel with no open slots left, or one full of tandem breakers squeezed in
- Lights that dim when the well pump, AC or a large appliance starts
- A fuse box, or a panel brand with a known failure history
- Any scorching, discoloration or burnt smell near the box
Why coastal homes are a different job
In a coastal install the details that matter are the ones you cannot see later: the right enclosure and hardware for the environment, connections torqued to spec, proper sealing where conduit enters, and a meter socket and exterior disconnect that are actually rated for what they are sitting in. Cutting corners on any of that gets you a panel that looks new and corrodes on the same schedule as the last one.
We also check the meter socket and the service entrance while we are there. Corrosion rarely stops politely at the panel, and finding it at the socket before the utility does saves you an emergency.
100 to 200 amp service upgrades
A lot of Cohasset homes are still on a service sized for a much simpler house. Once you add central air or a heat pump, a finished lower level, a hot tub, a well pump or a car charger, a 100 amp service runs out of headroom. We run the load calculation, tell you what the house needs, and coordinate the utility disconnect and reconnect and the town inspection so the work happens in one clean sequence.
