Electrical Panel FAQs
Your electrical panel is the heart of your home's electrical system. It safely distributes electricity throughout your home while protecting your wiring with circuit breakers. Whether you're wondering if your panel needs to be replaced, planning an upgrade, or experiencing breaker problems, this page answers the most common electrical panel questions we receive from homeowners throughout Reno, Sparks, Spanish Springs, North Valleys, Verdi, Washoe Valley, Carson City, Dayton, Fernley, and Incline Village.
Electrical Panel Basics
What is an electrical panel?
An electrical panel, sometimes called a breaker panel or load center, receives electricity from your utility company and distributes it to the individual circuits throughout your home. Every circuit in your home is protected by a circuit breaker located inside the panel.
How long do electrical panels last?
Most modern electrical panels last between 25 and 40 years. However, age alone doesn't determine whether replacement is necessary. Frequent breaker trips, corrosion, overheating, water damage, or obsolete equipment may indicate it's time for an inspection.
What does an electrical panel do?
Your panel distributes electricity safely throughout your home while protecting circuits from overloads and short circuits. If too much electricity flows through a circuit, the breaker trips to help prevent wiring damage and reduce fire risk.

How do I know if my electrical panel should be replaced?

Can I upgrade from 100 amps to 200 amps?
Yes. Many homeowners upgrade to a 200-amp service when adding larger electrical loads such as EV chargers, hot tubs, workshops, or home additions. Whether your home needs an upgrade depends on a load calculation and your future electrical needs.

How much does an electrical panel replacement cost?
The cost varies depending on the size of the service, the existing equipment, permit requirements, utility coordination, and whether additional repairs are needed. Every home is different, so we recommend scheduling a free estimate for accurate pricing.
How long does it take to replace an electrical panel?
Most residential panel replacements can be completed in one day. Larger projects or service upgrades requiring utility coordination may take longer.
Older Electrical Panels
What is a Zinsco electrical panel?
Zinsco panels were commonly installed between the 1950s and 1970s. Many electricians recommend replacing them because certain breakers have a history of failing to trip properly during an overload or short circuit.
What is a Federal Pacific (FPE) panel?
Federal Pacific Electric panels are another older brand that many homeowners choose to replace because some breakers have documented reliability concerns.
Should I replace an older electrical panel even if it still works?
Not every older panel requires immediate replacement, but obsolete panels should be evaluated by a licensed electrician. A professional inspection can determine whether your panel remains safe or whether replacement is recommended.
Breakers & Electrical Capacity
Why do my breakers keep tripping?
Repeated breaker trips usually indicate overloaded circuits, damaged wiring, faulty appliances, or failing breakers. The breaker is doing its job by shutting off power to help protect your electrical system.

Can a breaker wear out?
Yes. Like any mechanical device, circuit breakers can wear out over time. Breakers that repeatedly trip or fail to reset should be evaluated by a licensed electrician.
Can my electrical panel handle an EV charger?
Many homes can accommodate an EV charger without replacing the panel, but it depends on your existing electrical load and available capacity. A professional load calculation determines whether upgrades are necessary.
Can my electrical panel handle a hot tub?
Many hot tubs require a dedicated 240-volt circuit. Whether your existing electrical panel can support one depends on your home's electrical demand and available capacity.
