Is it time for a new panel?

Most panels give warning signs long before they fail. Tap anything that sounds like your home and you’ll get a straight answer about what to do next.

Signs like these can have more than one cause. Only an on-site look can tell you which, and our estimates are free.

Your answer shows up here.

Every circuit in your home starts here.

This is the all-in-one meter and panel on the outside wall of most Southern California homes. Tap a breaker to follow its circuit, switch it off or see a trip. A panel upgrade replaces this assembly with one sized for the way you live now.

A bigger main, when you need it

The main breaker sets your home’s capacity. Common upgrades go from 100 or 150 amps to 200 amps; larger homes may need 400.

Room for every circuit

Each 120-volt circuit takes one space. EV chargers, ranges, dryers and heat pumps run on 240 volts and take two. A new panel leaves room for what’s next.

Protection built in

AFCI and GFCI breakers where code requires them, whole-home surge protection, and proper grounding and bonding.

Older panels

Still have a Zinsco or Federal Pacific panel?

Your lights may still work. The real question is whether your breakers will still trip when they need to. Some older panel designs have documented problems; others are simply worn out.

The worn breaker, with a loose and corroded connection at the bus bar, stays on while heat builds at that connection.bus barHealthy breakerTrips on an overload, as designed1-POLE · 20 A · 120/240 V~OFFON20LOADWorn breakerLoose, corroded connection at the bus1-POLE · 20 A · 120/240 V~OFFON20LOAD

What a breaker is supposed to do: when a circuit is overloaded, it trips and cuts the power. A worn breaker, or one with a loose or corroded connection at the bus bar, can stay on while that connection heats up. Illustration, not a real measurement.

Warning signs to take seriously

  • Breakers that trip again and againOften an overloaded circuit, sometimes a failing breaker. Either way, it’s worth a look.
  • A burning smell or a warm panel coverHeat at the panel is never normal. Stop using that circuit and call.
  • Buzzing or cracklingA loose connection or arcing can make noise before anything else happens.
  • Lights that flicker or dimEspecially when a big appliance starts. It can point to loose connections or an overloaded service.
  • Scorch marks, rust or melted plasticOn the panel cover, the door, or the breakers you can see with the door open.
  • A panel brand with known problemsZinsco, Federal Pacific Stab-Lok, or certain 1988 Challenger GFCI breakers. See below.

These signs can have more than one cause. Only an on-site check can tell you which.

Recognize your panel?

Warning

Zinsco and Sylvania-Zinsco

No recall · documented connection problems

Installed in many homes in the West through the 1970s. The breakers can lose contact with the bus bar, overheat and arc, and a breaker that has melted onto the bus may not trip.

How to spot it: “Zinsco” or “Sylvania” on the label inside the panel door.

Warning

Federal Pacific (FPE) Stab-Lok

Federal review closed in 1983 · no recall

The U.S. Consumer Product Safety Commission closed its investigation in 1983 without a recall. It found that some Stab-Lok breakers failed certain UL calibration tests, but said its data did not establish a serious risk.

Challenger (certain 1988 GFCI breakers)

Replacement program · specific breakers only

Not every Challenger panel. In 1988 Challenger offered to replace Type HAGF-15 and HAGF-20 GFCI breakers made between February 22 and April 29, 1988, because their ground-fault protection may not work.

Warning

Fuse boxes and decades-old panels

Age and wear

Fuses aren’t dangerous by themselves, but older fuse boxes and panels were sized for homes with far fewer appliances. Corrosion, loose connections and the wrong size fuse or breaker add up over the years.

How to spot it: Screw-in or cartridge fuses, rust on the box, or a panel that’s original to an older home.

Subpanel installation and replacement

We install new subpanels for garages, ADUs and home additions, and we replace and upgrade old ones. A subpanel adds breaker space where you need it. It doesn’t add power to your home: it shares what your main electrical service can supply.

When a subpanel makes sense

  • Your main panel is out of breaker spaces, but your service still has room to spare
  • A garage or workshop needs its own circuits for tools, a freezer or an EV charger
  • An ADU or home addition needs power close to where it’s used
  • An existing subpanel is old, damaged, full or undersized and needs replacing

What’s included

  • A load calculation, so we know your service can carry the new circuits
  • Correctly sized feeder wire and breaker
  • Grounding and bonding to code, with neutrals and grounds kept separate
  • A clearly labeled panel
  • We coordinate the required electrical permits and inspections with the appropriate city or county authority when the project requires them.

200-amp upgrade or a subpanel?

A subpanel may be enough if…

  • Your panel is full of breakers, but a load calculation shows spare capacity
  • You’re adding a few circuits in one area, like a garage or an addition
  • Your main panel is in good condition

You likely need a main-panel upgrade (often to 200 amps) if…

  • Your home will need more power than your service can supply
  • You’re adding several large loads, such as an EV charger plus a heat pump, an electric range or a spa
  • Your existing electrical service does not have enough capacity for the planned loads, based on a load calculation, or a licensed electrician identifies a panel condition that requires replacement.

Many homes need both: a bigger service at the main panel and a subpanel where the new circuits go. We decide with a load calculation at your free on-site estimate, not by guessing over the phone. If your project also needs a larger service or a new meter, your utility must approve and schedule its part. We coordinate that with you, and the utility sets the dates.

    2. A circuit tripped furing the extreme hear so I called Volta at 6pm and they were able to schedule service for the next day. On arrival, Eric and his associate were so polite and ready & willing to help. Luckily my problem was just a tripped circuit I didn't know about but they checked all the breakers and made sure everything worked before they left. I'd highly recommend Volta.

    Panel upgrade questions

    Straight answers to what homeowners ask us most. Still wondering about something? Call (844) 425-1889.

    How do I know if I need a panel upgrade?

    Common signs are breakers that trip often, lights that flicker or dim, a warm panel or a burning smell, an old fuse box, or a panel that’s decades old. You may also need more capacity before adding an EV charger, heat pump, air conditioning, solar or a remodel. Try the 60-second panel check above.

    Is a Zinsco or Federal Pacific panel dangerous?

    Not every one has failed, and neither brand was recalled. But both have documented problems: Zinsco breakers can lose contact with the bus bar and overheat, and in a federal review some Federal Pacific Stab-Lok breakers failed certain calibration tests. If you have one, have a licensed electrician evaluate it. See what’s documented.

    How much does a panel upgrade cost?

    It depends on your home: the panel size, the meter and service, the wiring and what your utility requires. That’s why we don’t quote panel work over the phone. Call (844) 425-1889 for a free on-site estimate; you get a clear quote before any work starts. Financing options available for qualifying projects.

    Do you handle the permit, inspection and utility?

    Yes. When your project needs them, we pull the permit, schedule the inspection with your city or county, and coordinate the power shut-off and reconnection with your utility, such as SCE or LADWP.

    How long does a panel upgrade take?

    Electrical panel replacement timelines and power interruptions vary depending on the existing electrical system, the scope of work, and any required permit or utility coordination. We give you a clear timeline at your free on-site estimate.

    Do I need a 200-amp panel?

    Not always. The right size depends on what your home runs now and what you plan to add. At the estimate we look at your loads and recommend the size that fits: 100, 150, 200 or 400 amps. If your panel is simply out of breaker spaces, a subpanel may solve it without a full upgrade. See subpanel installation above.

    Can you add a subpanel to my garage, ADU or addition?

    Yes. We install new subpanels for garages, workshops, ADUs and home additions, and we replace old or damaged ones. First we check that your main service can support the new circuits. If it can’t, we’ll explain your options, including a service upgrade. Call for a free on-site estimate.

    Panel upgrade or panel replacement: what’s the difference?

    A replacement swaps an old or damaged panel for a new one of the same size. An upgrade also raises your home’s capacity, which usually means a larger main breaker and service and more coordination with the utility. We tell you which one your home needs.

    Can you prepare my panel for an EV charger, solar or a heat pump?

    Yes. We size the new panel for what you have now and what you plan to add, and we can install your EV charger at the same time. See EV charger installation.

    Do you offer a warranty?

    Yes. Our work comes with a 2-year labor warranty, and the equipment carries the manufacturer’s warranty of up to 10 years.
