About This Service
What Is a Panel Upgrade?
Westminster’s housing stock is largely mid-century, single-story ranch homes built between 1955 and 1975, many still on original 60-amp or 100-amp panels. Neighborhoods around Little Saigon and the Bolsa Avenue corridor often have owner-added ADUs or additions that overload that original capacity. A panel upgrade replaces the main service panel with a higher-amperage unit, typically 200A, to support central air, EV charging, and added living space. This requires coordinating a service disconnect with Southern California Edison and a permit through the City of Westminster Building Division.

Questions
Panel Upgrade FAQs
How do I know my Westminster home needs a panel upgrade instead of a repair?
If your panel is an older 60A or 100A unit, uses obsolete breakers, or can’t support new appliances or EV charging, an upgrade is usually the right call.
Will Southern California Edison need to be involved in my upgrade?
Yes, upgrading your main panel requires a coordinated service disconnect and reconnect with SCE, which we schedule as part of the job.
Do I need a City of Westminster permit for a panel upgrade?
Yes, panel upgrades require a permit and inspection through the Building Division.
Will an addition or ADU affect the size of panel I need?
Likely yes. Added square footage or a detached ADU adds load, which we factor into your load calculation before recommending panel size.
