Frequently asked questions about Service Upgrade Cert

When do I need a service upgrade?
Common reasons include adding high-demand loads (EV charger, heat pump, hot tub), renovating with additional circuits, replacing an obsolete panel (Federal Pacific, Zinsco), or when the existing service cannot support the calculated load.
Do I need utility company coordination?
Yes. Service upgrades require coordination with the utility company for disconnection and reconnection of the meter. Most utilities require advance scheduling and may need to install a new meter or transformer.
