What Are Circuit Breakers and How Do They Work?
Circuit breakers are a vital part of any modern electrical system. They protect your wiring from damage and your home from electrical fires, which can be caused by issues such as:
- Short Circuits: Irregular connections between currents that can lead to dangerous conditions.
- Overcurrents: Electrical currents that are too large, which can also lead to dangerous conditions.
When the circuit breaker detects irregularities, it cuts off the current. This prevents fires, as well as damage to your wiring and appliances.

Precision Matching for Safe Power Distribution
Ongaro & Sons ensures every circuit breaker we install is perfectly matched to your home’s voltage and amperage requirements. We go beyond minimum safety standards and local codes to deliver reliable, long-lasting protection that keeps your electrical system running smoothly and safely.
Tailored Breaker Types for Complete Protection
We install the right type of circuit breaker for every application, whether it’s a standard model or an advanced GFCI or AFCI breaker. These specialized breakers guard against shocks, arcs, and faults while keeping your home fully compliant with California’s most up-to-date electrical safety regulations.
Why Breakers Trip, And What We Do About It
Circuit breakers trip to stop dangerous conditions like overloads, short circuits, or ground faults. If your breaker keeps tripping, our licensed electricians investigate and resolve the underlying issue, restoring your system’s safety and preventing future disruptions or potential fire hazards.
AC vs. DC: Know Your Home’s Power Flow
Most homes rely on Alternating Current (AC) for appliances and lighting, while Direct Current (DC) powers things like battery backups or solar equipment. Understanding both helps us properly configure your breaker panel and ensure safe, efficient power delivery throughout your home.
Circuit Breaker Replacement
Our team is proud to offer circuit breaker replacement and upgrades to our neighbors in the North Bay. Here’s how the process works:
- We will provide an in-home inspection. This allows us to determine if a circuit breaker replacement is warranted. In some instances, a panel replacement or rewiring will do.
- We’ll provide you with an up-front estimate. Our pricing is transparent. We’ll never charge you for something you don’t need, no surprise fees.
- We’ll complete the installation to the highest standards. Our electricians stick to the National Electrical Code (NEC), which is the United States standard for the safe installation and operation of electrical wiring and appliances.
Were you aware that electricians stopped installing fuse boxes in new homes built after 1960? Even if they have been modified, fuse boxes aren’t designed to meet today’s energy demands. If your older home still has a fuse box, our team of electricians can help you upgrade to a modern circuit breaker that meets your home’s energy needs.

Signs You Need Your Circuit Breaker Replaced
Circuit breakers can be expected to last between 30 to 40 years. While they have a relatively long life span, they eventually need to be replaced. Additionally, older models may not be able to handle modern electrical demands. That’s why it’s essential to schedule an electrical inspection whenever you move into a new home.
Think you might need a new circuit breaker? Besides age, here are a few signs to watch for:
- Scorching or a burning smell: This is a serious red flag. It likely means the wiring is overheating or melting from overcurrent, a potential fire hazard. Shut off your main power and call Ongaro & Sons.
- Breakers that trip constantly: This may mean a breaker is worn out or protecting an overloaded circuit. If you find yourself resetting breakers regularly, it’s time for an inspection and likely a replacement.
- A warm breaker panel: A properly functioning electrical panel should never feel hot. Warmth may be due to loose connections, internal damage, or failing components that need immediate attention.
- Buzzing or humming noises: Strange sounds from your breaker panel can indicate internal arcing or faulty breakers, often an early warning sign of serious issues.
- Flickering or dimming lights: If lights dim or flicker when appliances turn on, your breaker may be struggling to keep up, a sign it needs to be upgraded for better performance and safety.

Why Ongaro & Sons for Circuit Breaker Installation
A breaker that keeps tripping is doing its job. The question is what it is protecting you from.
Schedule Service →The cause gets found before the breaker is changed
Repeated tripping is a symptom. Replacing the breaker without finding the overloaded circuit, the damaged cable or the failing appliance removes the warning and leaves the fault.
Correct breaker for the panel and the circuit
Breakers are not universal. The wrong brand or type in a panel is a listing violation and a real hazard, and it is common in houses with a history of small fixes.
AFCI and GFCI applied where code requires
Arc fault and ground fault protection requirements have expanded. We fit what current code requires for the circuit rather than matching whatever was there.
Obsolete and recalled panels identified
Some panel brands cannot be made safe with a new breaker. If yours is one of them, we will say so rather than sell you a part.
C-10 licensed, since 1932 in the North Bay
Ongaro & Sons has held C-10 continuously alongside an active California contractors licence first issued in 1963, working across Marin, Sonoma and Napa.

Read MoreFrequently Asked Questions
Can I install a circuit breaker myself?
Installing breakers involves working inside the panel and poses shock or fire risks. Always leave this work to a licensed electrician.
Does a whole-home surge protector cover power strips and outlet surge devices?
Yes, it protects the entire system, but local outlet surge protectors still offer additional layer of protection for sensitive electronics.
How do I know what size breaker I need?
Breaker size depends on the circuit's wiring and the appliance load. An electrician calculates load capacity to ensure proper sizing and code compliance.
Should I add a breaker for new appliances?
If your panel has available capacity, a dedicated breaker can be added for appliances like electric ranges or dryers to ensure proper power and protection. However, it is not necessary if your existing circuit breaker works well and has the capacity for an updated appliance.
What’s the difference between a fuse and a circuit breaker?
Both protect your home from electrical overloads, but breakers can be reset, while fuses must be replaced. Modern homes use circuit breakers for convenience and safety.
When should I replace or install a new circuit breaker?
If your breaker trips frequently, won’t reset, or shows signs of damage or burning, it should be replaced immediately for safety.
