⚡ 200 Amp Electrical Service Upgrades


Power Your Home Safely with a Modern Electrical System



Is Your Electrical Service Holding You Back?


Many homes in Hudson, Nashua, and surrounding NH areas were built with 100-amp service—far below what today’s homes demand.


If you’re running HVAC systems, EV chargers, generators, or modern appliances, your current service may be overloaded, unsafe, and outdated.


Upgrading to 200-amp electrical service gives your home the power it needs—safely and reliably.



What Is a 200 Amp Service Upgrade?


A 200-amp service upgrade increases the total electrical capacity coming into your home. This includes upgrading:
