Panel & Service Upgrades

Modernize the electrical backbone before new loads turn into nuisance trips or unsafe workarounds.

Upgrades

Capacity first, hardware second.

Panel upgrades get sold on fear. We would rather show you the numbers. We open the panel, document what is in it, add up the real demand, and tell you whether you need 200 amps, a subpanel, or just a few corrections. If a subpanel does it, that is what goes in writing.

What the job includes.

  • 01
    Panel and service replacement

    Main panels, subpanels, meter combos, and feeders replaced with current equipment and room left for what comes next.

  • 02
    Load and capacity reviews

    A written look at existing demand versus service rating so the upgrade is sized on numbers instead of a guess.

  • 03
    Dedicated circuits for new equipment

    Circuits added during the upgrade for EV charging, HVAC, mini-splits, pool equipment, or a future casita.

  • 04
    Breaker and grounding corrections

    Obsolete or recalled breakers, double-tapped lugs, missing bonds, and undersized grounding electrodes brought up to standard.

  • 05
    Utility and inspection coordination

    We handle the release paperwork, schedule the disconnect and reconnect, and keep the outage window as short as the work allows.

  • 06
    Neat labeling and final testing

    Every circuit traced and named on a typed directory, with voltage and torque checks recorded before the cover goes on.

The panel is usually telling you before you ask.

  • Federal Pacific, Zinsco, or Challenger equipment is still in service.

  • There are no open spaces left, or tandem breakers are filling the gaps.

  • An insurer, inspector, or buyer flagged the panel in writing.

  • Rust, scorching, buzzing, or warm breakers are visible at the enclosure.

Four steps, every time.

The scope changes from job to job. The sequence does not, so you always know what happens next and what it depends on.

  1. Assess condition and demand

    We open the panel, document what is in it, and calculate the load the property runs today.

  2. Size the upgrade

    Service rating, panel location, feeder path, and grounding are decided before equipment is ordered.

  3. Coordinate the outage

    Utility release, permit, and inspection are sequenced so power is off for the shortest practical window.

  4. Energize and document

    The new service is tested under load, labeled, and photographed so you have a record of what was installed.

Questions about panel & service upgrades.

How do I know whether my electrical panel needs an upgrade?

Common reasons include insufficient capacity for new equipment, obsolete or damaged equipment, repeated capacity problems, insurance or inspection findings, or a larger remodel that changes the property's loads.

What happens before a panel or service upgrade?

The process starts with a load and condition review, then equipment, grounding, routing, utility requirements, permits, inspection, and any required outage are coordinated.

Can a panel upgrade add room for an EV charger or new HVAC?

Yes. Current and planned loads can be evaluated together so the selected equipment supports the property instead of solving only one immediate addition.

How long is the power off during a panel upgrade?

Most of the day, though the exact window depends on the equipment, the utility, and inspection timing. The schedule is set in advance so you can plan around it.

Is 200-amp service always the right answer?

No. The right service size comes from a load calculation. Some properties are fine at 125 or 150 amps, and others need more once EV charging, HVAC, and pool equipment are counted.
