Why Do Some La Puente Homes Need a Panel Upgrade?

Electrical panel upgrades in La Puente rarely start at the panel itself; they are triggered when someone buys a high-draw appliance, like a heat pump or an EV charger, that exceeds the home’s safe operating limit. Here are the three most common additions that prompt a panel replacement, and the fixes we apply to each.

A Level 2 charger generally requires a dedicated 240-volt circuit, which can add a significant electrical load to an older panel. If the existing 100-amp service does not have enough capacity, an upgrade to 200 amps may be needed before the charger can be installed.

Submitting plans for Accessory Dwelling Unit (ADU) permitting requires verifying your property’s total electrical capacity before city inspectors sign off on construction. Before submitting plans to local building departments, our certified electricians perform National Electrical Code (NEC) load calculations to determine whether your existing panel can support a secondary feeder subpanel or if a main service panel upgrade is required.

When high-amp modern appliances try to run at the same time, an undersized system will start tripping breakers or overheating. Upgrading your service panel to a modern 200-amp capacity gives your home the necessary electrical headroom so every appliance can run simultaneously, delivering safe power.

  • How do I know I need an electrical panel upgrade? Signs that a home may need an electrical service upgrade include limited panel capacity, or future plans to add high-demand equipment such as an EV charger or ADU. United Electric Services can perform a load calculation to determine the home’s needs.
  • Is 200 amps enough of an upgrade for my home? The appropriate upgrade size depends on the home’s electrical load and planned equipment. United Electric Services calculates the required capacity before recommending an upgrade.
  • Upgrade first, or charger first? That depends on the available capacity in the existing panel. United Electric Services checks the electrical load before determining whether the panel needs to be upgraded before a Level 2 charger is installed.
  • Does Edison have to be involved during an electrical panel upgrade? A service change may require coordination with Southern California Edison for the utility disconnect and reconnect. United Electric Services handles that coordination as part of the project.
  • Is a permit required for an electrical panel upgrade service? Service upgrades require permitting and inspection through the City of La Puente Building and Safety Division. United Electric Services handles the required permit process.
  • How long will we be without power? The length of the outage depends on the scope of the service upgrade and the utility schedule. United Electric Services provides the expected schedule before the work begins.
  • Can we finance our electrical panel upgrade? United Electric Services offers financing through GoodLeap on qualifying projects. The company can provide financing details along with the project estimate, if you’re interested.

United Electric Services upgrades undersized or outdated panels to 200- or 400-amp service when the home’s electrical load requires additional capacity. The work may also include replacing the meter base or service entrance and installing required surge protection. Is your current panel holding you back? An EV charger installation may require an upgrade when the existing panel does not have enough capacity. When the panel has sufficient capacity and only specific components need attention, targeted electrical panel services can address the issue without a full upgrade.

Circuit breakers tripping when two high-draw appliances run simultaneously, a legacy 100-amp main service struggling under added electrical loads, or a panel with zero open slots are all signs that your panel has reached its operating ceiling. As highlighted in ENERGY STAR’s guide to making your home electric ready, main panel amperage and available bus bar space are the two primary factors homeowners must check before adding major electric equipment, like an at-home EV charger. Considering a tech upgrade? Both details can be verified directly on your panel door; and if your system is at capacity, an electrical panel upgrade ensures your home can safely support modern demand. Contact us today to request your free estimate.

United Electric Services provides free estimates and diagnostics, upfront pricing, and GoodLeap financing for qualifying larger projects upon approval. Your panel upgrade is also backed by our satisfaction guarantee. Call (626) 249-3525 to get started, or to request your free estimate.
