The only true way to determine the size panel your Arizona home needs is to have a professional calculate your home’s electrical load.
You see, every home has different appliances with different electrical needs so it’s impossible to give you a true answer without first inspecting your home and the appliances you have/don’t have.
But here’s what we can tell you: If your home’s electrical panel has less than 100 amps, you at least need to upgrade to a 100-amp panel since the National Electric Code requires every home to have an electrical panel with a minimum of 100 amps.
Note: The size of your current panel should be either stamped or on a rating sheet on the inside of the panel door (the side facing the breakers).
Now, with that said, a 100-amp panel isn’t your only option—and it might not even be large enough for your home’s electrical needs.
In this article, we’ll cover some general guidelines that will help give you a better idea of the panel size your home needs (but remember—these tips should never replace a professional electrical load calculation!).

Residential electrical panels come in various sizes, including:
If you currently have a 100-amp panel but don’t have many free breaker slots left, you should consider upgrading. Upgrading your panel will allow you to add more circuits/appliances to your home in the future.
• Electric heater (i.e. electric furnace)
• Electric hot water tank
• Electric dryer
• Electric range
• Central AC
Our suggestion? If you’re considering a 150-amp panel, go ahead and opt for the 200-amp panel instead.
Why? Well, the cost of a 150-amp panel vs a 200-amp panel is minimal. Plus, installing a 200-amp panel ensures that you’ll have more room to grow in the future if you ever plan on adding new outlets or appliances to your home.
...your home exceeds 3,500-4,000 square feet.
Most of the time, larger-than-average houses will have more appliances and circuits—which means a much higher electrical load. However, most of the time, it’s more effective to have a 200-amp panel with an additional 100 or 200-amp “subpanel” (a panel that feeds off your main electrical panel and provides more breaker slots for circuits far from the main panel).
