Electrical Panel & Service Upgrades in Los Angeles
If your breakers keep tripping, your electrical panel is outdated, or you are adding an EV charger, HVAC system, solar battery, generator, or other high-demand equipment, your property may need an electrical panel or service panel upgrade.
Many older homes in Los Angeles still operate on 100-amp electrical services that were not designed for today’s electrical demand. Upgrading to a 200-amp or 400-amp service can provide additional capacity, improved safety, and support for future electrical needs.
Calibay Electric & Security provides clean, code-compliant electrical panel upgrades for homes and businesses throughout Los Angeles, Woodland Hills, Calabasas, Encino, Sherman Oaks, and the San Fernando Valley.
For larger homes, ADUs, multiple EV chargers, pool equipment, battery backup systems, or heavy electrical demand, a 400 amp service upgrade may be required instead of a standard 200 amp panel upgrade.

Electrical Panel & Service Upgrades FAQs
How much does a panel upgrade cost in Los Angeles?
Panel upgrade cost depends on the existing panel, service size, utility requirements, panel location, wiring, permits, and inspection needs. Calibay Electric & Security provides a clear estimate after reviewing your electrical system.
Do I need a 200-amp or 400-amp panel upgrade?
That depends on your home’s electrical load, future equipment, EV charger needs, HVAC, battery backup, and overall power demand. We can evaluate your panel and recommend the correct service size.
How long does a panel upgrade take?
Timing depends on the project scope, permit requirements, utility coordination, and inspection schedule. After reviewing your property, we can explain the expected timeline clearly.
Can my panel handle an EV charger?
Sometimes yes, sometimes no. Before installing an EV charger, we check available panel capacity, breaker space, load requirements, and whether a dedicated circuit or electrical panel upgrade is needed.
Do I need a permit for a panel upgrade in Los Angeles?
Yes. Electrical panel upgrades usually require permits and inspection to meet electrical code and safety requirements.
What is the difference between a panel upgrade and a service upgrade?
A panel upgrade typically replaces the electrical panel, while a service upgrade may also include the meter, service conductors, grounding system, and utility coordination. Service upgrades are often required when increasing electrical capacity from 100A to 200A or 200A to 400A.
Can I upgrade from 100 amps to 200 amps?
Yes. Many older homes in Los Angeles upgrade from 100A to 200A service to support EV chargers, HVAC systems, battery backup systems, modern appliances, and future electrical needs.
Can I add a subpanel instead of replacing my main panel?
A subpanel can add circuit space, but it does not increase the electrical capacity of the service. A load calculation can determine whether a subpanel or a full service panel upgrade is the best solution.
