What Happens During an Electrical Panel Upgrade?

  • We run a full load calculation to size the new service to how you actually use the home.
  • We coordinate the Southern California Edison disconnect and reconnect so the cutover is safe.
  • A licensed electrician installs the new 200-amp panel, mounts it to meet seismic bracing requirements, and lands every circuit.
  • We pull the Glendora permit and meet the inspector so the upgrade is signed off, not just finished.
  • We test everything under load and walk you through the new panel before we leave.

Is Your Home Up To Date? Find Panel Upgrade Services Near You

Many older homes in Glendora were built before central air, EV chargers, and today’s appliance-heavy kitchens became part of everyday life. If your electrical system is struggling to keep up, an electrical panel upgrade can provide the additional capacity your home needs. Moving from 100-amp to 200-amp service can also give you more flexibility for future improvements, such as an EV charger, ADU, or battery backup system. United Electric Services handles electrical panel upgrades in Glendora and throughout the San Gabriel Valley as a licensed C-10 electrical contractor, License #1013599. Call (626) 249-3525 for a free estimate.

Panel Upgrade Triggers in Glendora Homes

Most panel upgrades in Glendora start with one of three projects, and each one asks more of the service than an old panel can give. Each is easier to plan when the electrical panel upgrade is sized before the rest of the work begins.

A Level 2 charger draws 16 to 40+ amps, and an older Glendora panel near its limit cannot add that safely. Upgrading first gives the charger a home and leaves room to spare.

Postwar Glendora homes were wired for a fraction of today’s demand. Moving to 200-amp service ends the nuisance trips and covers central air, the kitchen, and everything you have added since.

A new addition or an ADU adds circuits the original panel was never sized for. We upgrade the service so the whole property, old and new, runs from one properly rated panel.

United Electric: Your Local Panel Upgrade Specialists

Upgrading a home’s electrical service from 100 to 200 amps can involve more than replacing the panel itself. National cost data puts a 200-amp upgrade between $1,300 and $2,500, with costs rising when the project requires a new service panel or additional equipment. The final number you pay depends on the home’s existing service and the scope of the upgrade. Larger projects, including some 400-amp upgrades, can cost considerably more. Considering an upgrade? United Electric Services evaluates the home’s electrical demand before recommending a way forward, and provides pricing based on the work your system actually needs. Call (626) 249-3525 to book your free estimate.

  • How do I know if my Glendora home needs a panel upgrade? Constant tripping, a 100-amp service, no open breaker slots, or plans for an EV charger, central air, or an ADU are the usual signs. A load calculation settles whether an upgrade is the right call.
  • Do I need a permit to upgrade my panel in Glendora? Yes. A service upgrade needs a Glendora permit through the Civic Access portal and a Southern California Edison disconnect and reconnect. We handle both so the cutover is safe and inspected.
  • Is 200-amp service enough? For most Glendora homes, yes, even with an EV charger and central air. Larger all-electric homes with a pool or multiple EVs sometimes step up to 400-amp service.
  • What is the difference between a panel upgrade and a panel replacement? A panel upgrade increases your service capacity, usually from 100 amps to 200, so the home can carry more load, while a replacement swaps a failing or obsolete panel for a new one at the same size. Many Glendora jobs are both at once, since a tired old panel is the natural moment to add capacity for an EV or central air.
  • Do I need to upgrade my panel for an ADU in Glendora? Often yes. A Glendora ADU or JADU adds its own circuits, and frequently a kitchen, a heat pump, or an EV charger, so the existing panel may not have the capacity to carry the main house and the new unit together. A load calculation tells us whether a service upgrade belongs in the ADU plan.
  • Will a panel upgrade lower my electric bill? No, and anyone who promises that is overselling it. A panel upgrade buys you safe capacity and headroom for modern loads, not cheaper power, though it does make it practical to add efficient equipment like a heat pump or an EV charger down the road.
  • Does upgrading help during a Public Safety Power Shutoff? On its own no, but a modern panel is what makes adding a generator or battery backup straightforward for the next PSPS event. Call (626) 249-3525 to talk it through.

A modern 200-amp panel does more than stop nuisance trips. It gives you the capacity for a heat pump, an ADU, or the EV charger installation so many foothill households are adding, and it brings older wiring connections up to the current California Electrical Code. For a Glendora house still on postwar service, it’s the upgrade the rest of your projects depend on.

Breakers that trip when the AC and oven run together, lights that dim across the house, or a panel with no open slots can all mean you’re running out of electrical capacity. The same may be true if you’re trying to stretch 100-amp service across a growing list of modern appliances. Upgrading your panel is the best way forward in these cases, as it will allow you to safely and efficiently manage your home’s electrical load. Contact us today to learn more about Glendora electrical panel services, or to book your free estimate.

Whether it is an EV, an ADU, or just a house that is finally out of room, United Electric Services sizes the upgrade to what is next. Financing is available so the project fits your budget, License #1013599 means it’s done by a licensed and insured contractor, and every upgrade carries our satisfaction guarantee and a free estimate. Call (626) 249-3525 for an electrical panel upgrade in Glendora.
