Underground Power Line Replacement and 200 to 400 Amp Service Upgrade

This one was a big job. The homeowner had an underground power line that needed to come out, and the service needed a serious upgrade - going from 200 amps all the way up to 400 amps. That kind of jump doesn't just happen at the panel. It means excavating the yard, pulling old cable, running new conductors, and making sure everything from the utility connection to the meter base is sized correctly for the increased load.

Here's what that scope of work actually looks like on the ground - a trench cut across the property to access the buried line, hands-on work at the meter base against a beautiful old stone wall, and a crew digging in and drilling through to get the new cable properly routed. Nothing about underground service replacement is quick or clean, but it has to be done right because this is where all the power to your home originates.

A lot of older homes were built when 200 amps was plenty. But with EV chargers, solar systems, whole-home generators, and modern HVAC loads, that number fills up fast. Doubling the service capacity to 400 amps gives this home the headroom it needs to handle all of it - now and down the road. It also means the electrical infrastructure is no longer the weak link.

Underground service entrance cable replacement is one of those jobs that most homeowners don't think about until something goes wrong - a failed line, flickering power, or a utility company flagging an issue. Getting ahead of it, especially when you're already planning an upgrade, is the smarter move. We handle the excavation, the cable installation, the meter base work, and all the coordination that goes with it.
