Summary
The NEC’s Optional Load Calculation Method can help you find out whether your electrical panel safely supports your power needs. This method is used by industry professionals to calculate how much electricity you currently use when planning upgrades like EV chargers or heat pumps. Caccia Home Services offers a free calculator that can apply this method for you and compare your home’s current power draw to the capacity of your electrical panel so you can see whether it needs upgrading.
If you live in a home that was built more than 15 years ago, there’s a good chance your electrical panel won’t be able to keep up with modern conveniences like EV chargers, home spas, or heat pumps.
Older 60-amp and 100-amp panels were built in a time when homes here in the Bay Area really only needed to power the basics. Today’s appliances draw significantly more electricity, so trying to run them without upgrading first can completely overwhelm the panel or even start a fire.
Use the free tool below to estimate how much capacity your current panel has compared to how much you’ll need if you want to install new tech. If you’re in the red zone, contact our team at Caccia Home Services and get a quote for an electrical panel upgrade.
How to Use This Calculator
To get your results, just follow these simple steps:
- Square Footage: This is the total square footage of your home. If you don’t know, your best guess is fine, or you can use a median average of around 1700-2000 square feet.
- Panel Size: This is the size of your panel and/or service. You’ll usually find it on your main switch or breaker. If you can’t find it, check out the video further down in this post for a walkthrough.
- Current Major Appliances: Check the boxes for which appliances you have now and what you plan to add when you upgrade your panel.
- Get Your Result: Click “Estimate Load” to get your results.
If the tool suggests you need an upgrade, click “Schedule an Evaluation Now” to schedule an assessment. It’s that easy!
