If lights dim when the A/C starts or breakers trip often, you are likely at the limit of your panel. An electrical panel upgrade is the safe path to more power for new appliances, EV charging, or an addition. In this guide, we explain when a breaker box upgrade makes sense, what size panel you need, permits, costs, and timelines. ECM offers a free electrical safety inspection to homeowners across South Florida.
Can you upgrade a breaker box for more power?
Yes. Upgrading your electrical panel increases available amperage and the number of circuits your home can safely support. A modern 200‑amp or 225‑amp service is common for homes adding central A/C, electric ranges, tankless water heaters, hot tubs, or EV chargers. If your home still runs a 60‑ or 100‑amp service, an upgrade can eliminate nuisance trips and reduce overheating risks in old components.
When done by a licensed electrician, your upgrade brings the service entrance, grounding, bonding, panel, and breakers up to current code. In Palm Beach and Broward counties, this work requires permits and an inspection. ECM pulls all required permits and provides a written quote before work begins.
Signs you need more capacity
- Breakers trip when multiple appliances run together
- Lights flicker or dim when the A/C or microwave starts
- Panel is warm to the touch or has a burning odor
- You use many power strips or extension cords
- You are planning EV charging, a hot tub, or a room addition
- Your panel is obsolete or recalled, such as some Federal Pacific models
Review highlight: “They have also replaced my fuse box panel as well as other things I have contracted with them. Thanks ECM.” –Norma R.
What does a panel upgrade include?
A true service upgrade is more than swapping a box. A quality upgrade addresses the full path from the utility point of connection to your branch circuits.
Typical scope:
- Load calculation to size the new service and panel
- Utility coordination for power shutoff and reconnect
- New service entrance conductors and meter can if required
- New main disconnect and grounded, bonded panelboard
- AFCI and GFCI breakers where code requires
- Surge protection device to protect sensitive electronics
- Labeling, as‑built documentation, and permit closeout
ECM’s panel safety inspection identifies overheated breakers, loose aluminum conductors, and degraded wiring. If your home needs only targeted repairs, we will quote that. If capacity is the issue, we will recommend the right size upgrade and explain why.
Panel size: 100 amp vs 150 amp vs 200 amp
- 100 amp: Minimum for smaller, older homes with gas appliances
- 150 amp: Mid‑range option when adding some electric loads
- 200 amp: Today’s standard for most detached single‑family homes
- 225–400 amp: For large homes, dual EVs, or high‑demand electric appliances
The correct size depends on a Manual J style load review and the NEC demand calculation, not guesswork. Our electricians verify present and future loads so you do not buy twice.
Review highlight: “The other two companies were lower but were not pulling a Palm Beach County permit, was not upgrading the electrical... The two repair guys were fabulous.” –Marilyn M.
Cost factors and ways to save
Every home is different, but these items drive cost:
- Service size and panel brand
- Meter can and service mast updates
- Distance from utility and panel location changes
- AFCI/GFCI requirements and number of circuits
- Grounding upgrades and surge protection
- Drywall repair and cosmetic work
Ways to save without cutting corners:
- Combine projects once. Add EV and future kitchen circuits now to avoid repeat labor
- Choose repair where safe. If capacity is fine, targeted breaker or wiring fixes may be enough
- Use ECM’s free inspection to identify code priorities and avoid unnecessary extras
- Consider service contracts to spread repair risk over time
Safety first: the risk of obsolete panels
Some legacy panels have documented safety concerns. Federal Pacific brand breakers have been widely reported for not tripping reliably under fault. Overheating lugs, brittle insulation, and double‑tapped breakers are other common hazards in older panels. If your panel shows rust, scorch marks, or buzzing, schedule an inspection immediately.
A modern upgrade resolves insufficient distribution, replaces malfunctioning components, and brings your system to current safety standards. ECM performs the work to the highest professional standards and passes final inspection before energizing.
The permit and inspection process in South Florida
Upgrading a service requires coordination with your city or county and the utility.
What to expect:
- On‑site assessment and written quote
- Permit application and utility scheduling
- Material staging in one of our 137 fully stocked vehicles
- Power shutdown, safe removal, and installation
- County or city inspection and utility re‑energize
- Final walkthrough and labeling
In many Broward and Palm Beach municipalities, same‑day power restoration is common when scheduling is aligned. ECM’s 24‑hour emergency service helps minimize downtime if an urgent replacement is needed after a failure or storm event.
How long does a panel upgrade take?
- Inspection and quote: same day in most cases
- Permit lead time: a few days to two weeks depending on jurisdiction
- On‑site installation: typically 6 to 10 hours for a standard 200‑amp upgrade
- Final inspection and utility reconnect: often within 24 to 72 hours of install
We schedule around HOA rules and utility availability. For homes in Port St. Lucie, West Palm Beach, Boca Raton, Coral Springs, Deerfield Beach, and surrounding areas, our local teams know inspector preferences and common code corrections, which keeps projects moving.
Review highlight: “Have had ECM contract for 5 years... Had an electrician a couple of days ago and was on time, efficient and friendly.” –Maria B.
Can you add more circuits without a full upgrade?
Sometimes. If your panel still has amperage headroom and physical space, adding dedicated circuits for an appliance or a workspace may be enough. We evaluate conductor size, main breaker rating, and service entrance capacity before recommending a path. If you are out of space or near the main rating, a subpanel might be a short‑term option. For long‑term growth or high‑demand loads like EVs, a full service upgrade is usually smarter.
Breaker types you may need when upgrading
- Standard thermal magnetic breakers for general lighting and outlets
- AFCI for arc fault protection in living spaces
- GFCI for kitchens, baths, garages, and outdoor circuits
- Dual‑function AFCI/GFCI to satisfy both requirements in one unit
- 2‑pole breakers for 240‑volt appliances and EV charging
Choosing the right breakers is critical to pass inspection and protect your home. We match device ratings to conductor size and manufacturer listing.
EV chargers, heat pumps, and future proofing
Electrification is rising across South Florida. If you plan to install an EV charger, convert to a heat pump, or add an induction cooktop, size your service with tomorrow in mind.
Future proofing tips:
- Oversize conduit during upgrades for easy wire pulls later
- Leave spare breaker space for new circuits
- Install a whole‑home surge protector to protect electronics during storms
- Label circuits clearly to speed future service calls
Will an upgrade lower your energy bill?
The upgrade itself does not reduce kWh usage. It improves safety and reliability so equipment runs without voltage drop or nuisance trips. Energy savings come from the appliances you power with that panel. However, preventative maintenance can reduce wasted energy by keeping motors, connections, and breakers in good condition. ECM’s service contracts help avoid failures that lead to costly emergency work.

Common myths about breaker box upgrades
- Myth: You can just swap the main breaker for more amps. Reality: The service entrance, conductors, meter, and panel must all be rated for the new amperage.
- Myth: Tandem breakers are a safe way to add space. Reality: Only where the panel is listed for them, and capacity must allow.
- Myth: Permits are optional for small changes. Reality: Service upgrades require permits and inspections across South Florida.
What homeowners in South Florida ask first
- Can you keep power on during the upgrade? We plan for minimal downtime, but utility shutoff is needed during the swap. We work efficiently to restore power the same day when possible.
- Will my insurance require a new panel? Some insurers require removal of obsolete panels. We can provide documentation for underwriting after the upgrade.
- Do I need a 200‑amp service for an EV? Often yes, especially with electric ranges or dryers. We confirm with a load calc.

Frequently Asked Questions
Do I need a permit to upgrade my breaker box?
Yes. In South Florida, service upgrades require permits and inspections. ECM handles applications, utility coordination, and final approvals.
How much amperage do most homes need today?
Many homes benefit from 200 amps, especially with EV charging or electric ranges. We verify with a code compliant load calculation.
Can I add a subpanel instead of upgrading the main panel?
A subpanel can add circuit space, but it does not increase total service capacity. If loads exceed the main rating, upgrade the service.
How long will my power be off during the upgrade?
Most standard upgrades are completed in one workday. We plan shutoff windows with the utility to minimize downtime.
Are Federal Pacific panels dangerous?
Many reports show certain models fail to trip reliably. If you have a Federal Pacific panel, schedule an inspection to discuss replacement options.
