Home electrical panel inspection by Newport Coast Electric Orange County CA

Your electrical panel is the heart of your home's electrical system — and most homeowners never think about it until something goes wrong. At Newport Coast Electric, we've been inspecting, upgrading, and replacing electrical panels throughout Orange County since 1993. Whether you're in Newport Beach, Costa Mesa, or Irvine, understanding your panel can save you from costly repairs, safety hazards, and unexpected outages.


What Is an Electrical Panel and What Does It Do?


Your electrical panel — also called a breaker box or load center — is the distribution point for all electrical circuits in your home. It receives power from the utility company and distributes it through individual circuit breakers to every room, appliance, and outlet in your house.


Each circuit breaker is designed to trip — or shut off — when a circuit draws more power than it can safely handle. This protects your home's wiring from overheating and reduces the risk of electrical fires.


How to Read Your Electrical Panel


Most modern homes in Orange County have either a 100-amp or 200-amp service panel. Here's what that means:


  • 100-amp panel — Standard in older homes built before the 1980s. May not support modern electrical demands like EV chargers, HVAC systems, or large appliances.

  • 200-amp panel — Standard in most homes built after 1990. Supports the electrical needs of modern households including smart home systems and EV charging.

  • Circuit breakers — Each breaker controls one circuit. Single-pole breakers handle 120V circuits for lights and outlets. Double-pole breakers handle 240V circuits for dryers, ovens, and HVAC.

  • Main breaker — Controls power to the entire panel. Turning it off cuts power to the whole house.


5 Warning Signs Your Panel Needs Attention


Don't ignore these warning signs — they could indicate a serious safety hazard:


  1. Frequently tripping breakers — If a breaker trips regularly, your circuit may be overloaded or there may be a wiring fault.

  2. Flickering or dimming lights — Often caused by loose connections or an overloaded circuit.

  3. Burning smell near the panel — This is a serious warning sign. Call an electrician immediately.

  4. Panel feels warm or hot to the touch — Indicates a potential wiring issue or overloaded circuit.

  5. Outdated fuse box — If your home still has a fuse box instead of circuit breakers, it's time for an upgrade.


When Should You Upgrade Your Electrical Panel in Orange County?


You should consider a panel upgrade if:


  • Your home has a 60 or 100-amp service and you're adding major appliances

  • You're installing an EV charger at home

  • You're remodeling or adding square footage to your home

  • Your panel is more than 25-30 years old

  • You're experiencing any of the warning signs listed above


A 200-amp panel upgrade gives your home the capacity to handle modern electrical demands safely and efficiently — and adds value to your property.
