Overview
Size the service right the first time
An undersized service means failed inspections, nuisance trips and expensive upgrades later. An oversized one wastes money on gear, conductors and utility fees. A proper load calculation tells you what the building actually needs, and gives the building department the documentation it asks for.
We prepare electrical load calculations following NEC Article 220, using the method that fits the project: the standard method, the optional method for dwellings, or existing-load data for additions and service changes. Each calculation shows the loads, demand factors and results clearly enough for a plans examiner to follow.
Load calcs often lead to pricing questions, such as what a service upgrade or new panel will cost. We can roll the result straight into an electrical estimate.

Florida factors
Florida loads that change the math
Florida buildings carry heavier cooling loads than most of the country, and many homes still rely on electric heat strips for the few cold nights each year. Pool pumps, heaters, electric water heaters and outdoor kitchens add up quickly on residential services. Commercial projects often add generators, EV chargers and rooftop solar at the same time.
Code edition matters too. Projects permitted on or after December 31, 2026 fall under the 9th Edition Florida Building Code, which adopts the 2023 NEC. Earlier permits follow the 8th Edition and the 2020 NEC. We confirm which edition applies before we calculate.

| Generator sizing | Homes, clinics, commercial | Load list for standby or optional standby sizing |
Scope gaps we catch
Load calculation errors we catch
Many service problems trace back to a rushed calculation. These are the issues we check every time.
- Heat strips counted together with cooling instead of using the noncoincident rule
- Pool, spa and outdoor kitchen loads left out of residential calcs
- Missing future EV charging or solar interconnection loads
- Motor loads without the largest-motor adjustment
- Demand factors applied to loads where they aren't allowed
- Existing load data used without the required documentation

FAQs
Frequently asked questions
Straight answers to what contractors usually ask before sending plans. Don’t see your question? Call or email us.
Will a load calculation be accepted for my permit?
Our calculations are prepared to NEC Article 220 and laid out for review. Some jurisdictions require a licensed electrical contractor or engineer to sign permit documents; we’ll format the calc so your licensed professional can review and submit it.
Can you calculate load for an existing building?
Yes. We can use existing panel data, utility billing or demand data where the NEC allows it, plus the new loads you plan to add.
Do you size generators?
We provide the load information used to size standby generators. For a full priced package see our generator and emergency power estimating page.
Can you include EV chargers?
Yes. We calculate the added load and can show options like load management systems that may avoid a service upgrade.
How fast is turnaround?
Single-family and small commercial calcs are usually delivered within 1 to 2 business days.
Do you also price the electrical work?
Yes. We can follow the calculation with a full electrical estimate for the service and distribution work.
