Signs You May Need An Electrical Panel Upgrade:
-
Safety Concerns - Older homes in Phoenix were built with Zinsco or Federal Pacific electric panels. These brands are known to be fire hazards. We advise upgrading these for our client's safety. Of course, if you have any parts of your panel that are burning, rotting, or have faulty components - these are safety risks as well.
-
Increased Electrical Demand - Modern households use more electrical devices and appliances than older homes were designed to handle. Upgrading your electrical panel ensures it can support the increased load.
-
Home Renovations or Additions - Any significant renovation, remodel, or addition, such as adding a new room or installing a major appliance (like central air conditioning or a hot tub), will likely require an upgrade to accommodate the extra circuits and load.
-
Electrical Code Compliance - Electrical codes are updated periodically. An older electrical panel may not meet current standards. If you're planning to sell or rent your home, upgrading your panel will be required for compliance with the latest safety regulations. Don't worry, we're fully licensed electricians, which requires us to be familiar with the City of Phoenix electrical code compliance guidelines.
-
Tripping Breakers or Blown Fuses - If the existing panel frequently trips breakers or blows fuses, it may be because the panel is overloaded or there are underlying issues that an upgrade could resolve.
-
Installation of Advanced Technology - Adding smart home systems, electric vehicle chargers, or renewable energy systems like solar panels might require an electrical panel upgrade to handle the new technology properly.
-
Insurance Requirements - Some insurance companies may require an electrical panel upgrade as a condition for coverage, especially in older homes.
-
Age of the Panel - Electrical panels generally last around 25-40 years. If the panel is approaching or has exceeded this age range, an upgrade can prevent potential failures and improve the overall safety and efficiency of the home’s electrical system.

The Difference Between 100A & 200A Electrical Panels
100-AMP
-
Capacity and Power Handling - This is usually sufficient for smaller homes with basic electrical needs. It can support standard household appliances, lights, and small HVAC systems but might struggle with more power-hungry devices.
-
Number of Circuits - Fewer slots for circuit breakers limits the number of individual circuits you can run. This can restrict the ability to add new devices or circuits without overloading the panel.
-
Room for Expansion - A 100-amp panel might not have much room for expansion. If you need to add significant new electrical equipment, you might quickly reach the panel’s capacity.
-
Suitability for Modern Homes - Older homes often have 100-amp panels, which were sufficient for the electrical demands of the past. However, with the increasing number of electrical devices and appliances in modern homes, a 100-amp panel might become inadequate.
-
Safety and Efficiency - While still safe when properly used, a 100-amp panel can become overburdened more easily, leading to potential issues like tripped breakers or overheating, which can be a safety concern.
200-AMP
-
Capacity and Power Handling - This provides significantly more capacity and is better suited for larger homes or homes with high electrical demands. It can support multiple large appliances simultaneously, such as central air conditioning systems, electric heating, hot tubs, and electric vehicle chargers.
-
Number of Circuits - More slots allows for more circuits. This means more flexibility in distributing electrical loads and the ability to add more circuits for new appliances, home additions, or renovations.
-
Room for Expansion - Whether you're planning to add new rooms, upgrade your kitchen with modern appliances, or install advanced systems like home automation, a 200-amp panel can accommodate these needs without requiring another upgrade soon.
-
Suitability for Modern Homes - Modern homes typically have higher electrical demands, making a 200-amp panel more suitable. It can handle the load of contemporary lifestyles, which include multiple large appliances, high-tech gadgets, and energy-intensive systems.
-
Safety and Efficiency - A 200-amp panel is less likely to be overburdened, which can enhance overall safety and efficiency. It can distribute electrical loads more effectively, reducing the risk of overheating and electrical fires.
