Do I Need a Panel Upgrade for an Ev Charger in an Older Altadena Home?

Whether you need a panel upgrade for an EV charger in an older Altadena home depends on your current electrical capacity and the type of charger you plan to install. Because many older homes in our area were built with 100-amp panels, they often lack the spare capacity required to safely support a Level 2 charger.

To determine if an upgrade is necessary, we follow a professional evaluation process:

  • Load Calculations: Our licensed and insured electricians perform a detailed calculation that totals your existing lighting, appliances, and HVAC loads. We then add the EV charger at 125% of its continuous amperage to ensure the system can handle the demand.
  • Safety Inspections: In older Altadena properties, we also evaluate aging breakers, ungrounded circuits, or aluminum wiring that may be present in homes built between the 1940s and 1970s.
  • 2026 NEC Compliance: We ensure all work meets the latest electrical codes, including requirements for dedicated circuits and GFCI protection.

If the calculation shows insufficient capacity, we typically recommend a 200-amp panel upgrade to provide the necessary headroom for your vehicle and future home needs. As trusted local electricians, we handle the entire process, including obtaining permits through Los Angeles County.

We recommend hiring a licensed electrician and obtaining necessary permits for all electrical work. Contact us today for a free estimate; we will provide a transparent quote and help you explore any available rebates to offset the costs.
