Answers to Common Questions
View All FAQsWhat Is Considered an Electrical Service Upgrade for Homeowners?
An electrical service upgrade increases your home’s electrical capacity and replaces key service equipment. Most jobs raise capacity from 100 amps to 200 amps to support new circuits and appliances. In Norwood and nearby towns, Castle Electric secures permits, coordinates inspections, and installs a new meter, service wiring, and main panel. Grounding and bonding are updated to enhance safety. Upgrades are common for EV chargers, heat pumps, additions, or frequent breaker trips.
