When Should You Call a Residential Electrician for an Electrical Panel Upgrade?

Fri, 07 Aug 2026 16:38:14 GMT

Knowing the warning signs that point to an electrical panel upgrade can protect your home and family from serious hazards. A residential electrician can assess your panel and tell you whether repair or full replacement makes sense. Homes in Farragut, TN, often carry older wiring systems that simply were not built for today's power demands, making this a timely topic for Knox County homeowners. As more households add smart devices, home offices, and larger appliances, the gap between an aging panel's capacity and everyday electrical demand only grows wider.

Warning Signs Your Panel May Need an Upgrade

Your breaker panel needs attention when it can no longer keep up with your household's power load. Several clear warning signs may indicate it is time to call a licensed residential electrician serving Farragut, TN .

Breakers That Trip Repeatedly

A breaker that trips once is doing its job. A breaker that trips repeatedly under normal use is a sign your circuits may be overloaded. This often happens in older Farragut homes where the original panel was sized for far fewer appliances than today's households use.

Flickering or Dimming Lights

Lights that flicker or dim when you run the dishwasher or air conditioner suggest your panel is struggling to distribute power evenly. This is especially common in Knox County homes built before the 1990s, where 60-amp or 100-amp panels were standard.

A Burning Smell Near the Panel

A burning odor near your breaker box is a serious warning. It can indicate overheating wires or a failing breaker that may pose a fire risk. Do not ignore this sign. If you notice a burning smell, shut off power at the main breaker if it is safe to do so, and contact a residential electrician promptly.

Your Panel Still Uses Fuses

Fuse-based panels are outdated and may not meet current Tennessee electrical code requirements. If your home still has a fuse box rather than circuit breakers, an upgrade is likely overdue and may also be required before a home sale or insurance renewal. Some insurance providers charge higher premiums or decline coverage altogether for homes with fuse panels, since replacement fuses are harder to find and more prone to improper sizing.

You Are Adding an EV Charger or Major Appliance

Electric vehicle chargers, whole-home generators, and high-efficiency HVAC systems can require dedicated high-amp circuits. Many Farragut homes near Turkey Creek and Hardin Valley are seeing growing interest in EV chargers as new developments bring newer vehicles into the area. Your existing panel may not have the capacity to support these additions safely. A qualified residential electrician can evaluate your current service and recommend the right upgrade path. Level 2 EV chargers, for example, typically require a dedicated 240-volt circuit, which many older panels simply do not have room to add without an upgrade.

Your Panel Is 25 or More Years Old

Panels do not last forever. A unit that is 25 years old or more may have outdated components that no longer perform reliably. Age alone can be a valid reason for a professional inspection by a residential electrician.

What Does an Electrical Panel Upgrade Involve?

A panel upgrade typically means replacing an outdated or undersized breaker box with a unit that can handle your home's current and future power needs. A licensed electrician will evaluate your existing service capacity, identify any code compliance issues, pull the necessary permits, and coordinate with your local utility provider if a service upgrade is also needed. In Tennessee, electrical contractors must be licensed with the Tennessee Board for Licensing Contractors, so always verify credentials before hiring. Most residential panel upgrades can be completed in a single day, though homes requiring a service line upgrade or additional permitting may take longer. Your electrician should be able to walk you through the expected timeline and any inspection requirements before work begins.

Upgrading to a 200-amp panel is a common solution for households running multiple large appliances. If you plan to add EV charging or a solar system, your electrician may recommend planning for even greater capacity now to avoid a second upgrade later.

Choosing the Right Electrician for the Job

Not every electrical contractor has the same level of experience with panel upgrades. Ask about experience with your specific panel brand and amperage needs, and confirm that any permits and inspections will be handled as part of the project. A reputable electrician will also carry proper liability insurance and stand behind their work with a written warranty.
