7 Warning Signs Your Gilbert Home Needs a Panel Upgrade
An electrical panel won’t always fail spectacularly. Often, it gives subtle warnings that it’s struggling to keep up. Recognizing these signs is crucial for preventing a hazardous failure. If you notice any of the following issues in your home, it’s time to call JLM Electric for a professional panel inspection.
Frequent Circuit Breaker Tripping: If you have to make regular trips to your panel to reset breakers, it’s a clear sign your circuits are overloaded and the panel can’t handle your home’s electrical demand.
Flickering or Dimming Lights: When your lights dim every time a large appliance like your AC unit or refrigerator kicks on, it indicates your panel is straining under the load.
You Still Have a Fuse Box: Old-fashioned fuse boxes with screw-in fuses are obsolete and were not designed for the power needs of modern homes. They lack the safety features of modern breaker panels and can be a serious fire risk.
The Panel Feels Warm or Makes Crackling/Buzzing Noises: A panel should be cool to the touch and completely silent. Any heat or audible noise is an immediate red flag for dangerous loose connections or failing components. Call for emergency service immediately.
You See Scorch Marks or Smell a Burning Odor: Any sign of burning, melting, or corrosion on or around your panel indicates dangerous arcing is occurring. This requires immediate professional attention.
You’re Planning a Major Renovation or Appliance Addition: If you’re adding a new room, a swimming pool, a hot tub, or a Level 2 EV charger, your current panel likely won’t have the capacity or the physical space to support the new circuits required.
Your Home is Over 25 Years Old: If your home was built more than 25 years ago and still has its original panel, it was likely a 60-amp or 100-amp service. The modern standard is 200 amps to safely power today’s technology.
The Hidden Danger in Arizona Homes: FPE and Zinsco Panel
A significant number of homes built in the Phoenix area, including parts of Gilbert, Mesa, and Chandler, between the 1950s and 1980s were fitted with electrical panels that are now known to be extremely dangerous. If your home has a Federal Pacific Electric (FPE) Stab-Lok panel or a GTE-Sylvania/Zinsco panel, you should have it replaced immediately.
Federal Pacific Electric (FPE) Stab-Lok Panels
These panels are notorious for having circuit breakers that fail to trip during an overload or short circuit condition. An estimated 1 in 3 of these breakers are defective. This failure means that instead of shutting off the power, the breaker allows the current to continue flowing, causing the circuit wiring to overheat and creating a severe fire hazard. Many insurance companies will not cover a home with an active FPE panel.
How to Identify: Look for a panel with the name “Federal Pacific” or “Stab-Lok” on the cover or inside. The breakers often have a distinctive red stripe across the switch.
GTE-Sylvania/Zinsco Panels
Zinsco panels have a major design flaw in how their breakers connect to the aluminum bus bar. The connection can corrode over time, leading to arcing and overheating. The breakers have also been known to melt to the bus bar, preventing them from tripping and creating a condition where power is still flowing even when the breaker is in the “off” position.
• How to Identify: Zinsco panels often have brightly colored breaker switches (red, green, blue). The brand name “Zinsco,” “GTE-Sylvania,” or “Kearney” may be on the panel.
24/7 Electrician Services – Safe and Efficient
Comprehensive Electrical Solutions for Your Home & Business
At JLM Electric, we handle all types of electrical work, from minor repairs to major installations. Our team of licensed electricians is equipped to provide safe, efficient, and code-compliant solutions for any challenge.
Main Electrical Panel Upgrades
This is our most common service. A panel upgrade, or “heavy-up,” involves increasing your home’s total electrical capacity. We will replace your old 100-amp or 150-amp panel with a new 200-amp panel (or larger, if needed).
Circuit Breaker Replacement
If you have a single breaker that is faulty, constantly tripping, or failing to reset, we can replace it without needing to replace the entire panel (unless the panel itself is obsolete or damaged).
Fuse Box to Breaker Box Conversion
If your home still operates on an old fuse box, upgrading to a modern circuit breaker panel is one of the most critical safety improvements you can make. A new breaker panel is safer, more convenient, and necessary to obtain homeowners insurance in many cases.
Subpanel Installation
If you are adding a major addition, a detached workshop, or a casita in your Queen Creek property, a subpanel is often the best solution. A subpanel is a smaller, secondary electrical panel that is fed from your main panel, providing dedicated power to a specific area of your property without overloading your main service.
The Panel Upgrade Process with JLM Electric
We make the panel upgrade process straightforward and transparent.
Free On-Site Consultation: We’ll visit your home to assess your current panel, discuss your future power needs, and determine the right size panel for your home.
Detailed, Upfront Quote: You will receive a firm, written quote detailing the full scope of work and all associated costs. There are no hidden fees.
Permitting and Utility Coordination: We handle all the necessary paperwork, pulling the required electrical permit from the City of Gilbert or Town of Queen Creek and coordinating the scheduled power disconnection and reconnection with SRP or APS.
Professional Installation: On the scheduled day, our licensed electricians will perform the full panel replacement. This is typically a full-day job during which your power will be off for several hours. We work efficiently to minimize this downtime.
City Inspection: After the installation is complete, we will coordinate with the city inspector to conduct the final inspection and ensure all work is 100% up to code.
Final Walkthrough: We’ll walk you through your new panel, explaining each circuit and answering any questions you have, ensuring you are completely satisfied with our work.
Frequently Asked Questions About Panel Upgrade
Get answers about our repair services, troubleshooting processes, response times, and common electrical issues we fix.
How much does a panel upgrade cost in Gilbert, AZ?
The cost of a main panel upgrade can range from $2,500 to $5,000 or more, depending on the size of the panel, the condition of the existing wiring, and the complexity of the job. We provide free, detailed estimates so you know the exact cost for your specific situation.
How long will my power be out during a panel upgrade?
For a standard main panel upgrade, you can expect the power to be out for approximately 4 to 8 hours. We schedule the work with the utility company to minimize this time as much as possible.
Is a 200-amp panel really necessary?
For most modern homes, yes. A 100-amp panel can be easily overwhelmed by central air conditioning, an electric vehicle charger, an electric stove, and multiple computers and TVs running at once. A 200-amp panel provides the capacity and safety margin needed for a typical family’s lifestyle.
